To do. Examples of such discs include CD (Compact Disc), DVD (Digital Versatile Disc) and Blu-ray (registered trademark) discs.
Instead of such a disk device 3, a data recording unit that reads and records data on other removable media (for example, a semiconductor memory card) may be employed.

[Configuration of control device]
The control device 4 executes the program stored in the storage device 2 and controls the operation of the data recording device 10. Such a control device 4 is configured as a circuit board and is connected to each other via a bus line, a network interface 41, a general-purpose connection interface 42, an input device interface 43, a display device interface 44, a storage device interface 45, a drive interface 46, a memory 47 and CPU 48. Signal transmission (including information input / output) between the components 41 to 48 is performed via a bus line. In the following description, the term “interface” may be abbreviated as “IF”.

The network IF 41 establishes a communication connection with a device on a network (for example, the Internet), transmits information input from the CPU 48 to the device, and outputs information received from the device to the CPU 48. Such a network IF 41 includes a wired communication module including a connector through which a communication cable can be inserted and removed, and a transmission / reception unit that transmits and receives information via the connector, and a wireless communication module that communicates with an external device wirelessly. . Examples of such a wired communication module include a wired LAN module into which a LAN (Local Area Network) cable can be inserted and removed, and examples of the wireless communication module include a wireless LAN module.

The general-purpose connection IF 42 is a general-purpose interface that can be connected to various devices such as a camera and a music player. The general-purpose connection IF 42 transmits / receives information to / from the external device and outputs information acquired from the external device to the CPU 48. Examples of the general-purpose connection IF 42 include a USB (Universal Serial Bus) interface and a Bluetooth (registered trademark) interface.

The input device IF 43 outputs an operation signal input from the input device 91 to the CPU 48 in accordance with a user input operation.
The display device IF 44 is connected to the above-described display device 92, and outputs an image signal input from the CPU 48 (an image signal corresponding to an image generated by a display control unit 482 described later) to the display device 92. An image corresponding to the image signal is displayed. Examples of such an image signal include an image signal for displaying a screen (for example, an application execution screen) indicating an operation state of the data recording apparatus 10. When an image processor such as a VDP (Video Display Processor) and a GPU (Graphics Processing Unit) is provided, the display device IF 44 outputs an image signal input from the image processor to the display device 92. To do.

The storage device IF 45 includes a connector connected to the storage device 2 described above, and a driver that controls the operation of the storage device 2 under the control of the CPU 48. Then, the storage device IF 45 acquires data of the area corresponding to the command input from the CPU 48 from the storage device 2 and outputs the data to the CPU 48. In addition, the storage device IF 45 stores data input from the CPU 48 in the storage device 2.

The drive IF 46 includes a connector connected to the disk device 3 and a driver that controls the operation of the disk device 3 under the control of the CPU 48. Then, similarly to the storage device IF 45, the drive IF 46 acquires data in the area corresponding to the command input from the CPU 48 from the disk mounted on the disk device 3 and outputs the data to the CPU 48. Further, the drive IF 46 causes the disk device 3 to record data input from the CPU 48 on the disk.

The memory 47 includes a RAM 471 and a flash memory 472.
The RAM 471 temporarily stores programs developed by the CPU 48 and data processed by the CPU 48, and functions as a work area for the CPU 48.
The flash memory 472 stores a basic control program such as BIOS (Basic Input / Output System). The contents stored in the flash memory 472 are referred to by the CPU 48.

[CPU configuration]
The CPU 48 executes the OS stored in the storage device 2 and controls the operation of the data recording device 10. In addition, the CPU 48 executes a data recording program stored in the storage device 2. This data recording program is a program for managing information indicating recorded data in addition to recording data stored in the storage device 2 on a disk.
In this embodiment, the data recording program is acquired via a network and installed in the storage device 2 in advance. However, the data recording program is distributed by a recording medium such as a semiconductor memory or a disk and installed in the storage device 2. Also good. Further, the configuration is not limited to being installed and executed, and the CPU 48 may appropriately read from a recording medium or the like and execute a data recording program.

FIG. 2 is a block diagram showing functional means 481 to 490 of the CPU 48 when executing the data recording program.
When executing the data recording program, the CPU 48, as shown in FIG. 2, includes a folder generation unit 481, a display control unit 482, a data writing unit 483, a record availability determination unit 484, a data extraction unit 485, a recording control. Means 486, management information generation means 487 (corresponding to the folder structure information generation means and management information generation means of the present invention), data reading means 488, reconstruction means 489, and data search means 490.
Hereinafter, functions of the respective units 481 to 490 will be described together with respective processes performed by the respective units 481 to 490.

[Processing at startup]
FIG. 3 is a flowchart showing the startup process SA.
When the OS is started or when an operation signal for executing the data recording program is input from the input device 91, the CPU 48 reads the data recording program and executes the startup processing SA shown in FIG.
In this startup process SA, first, the CPU 48 determines whether or not initialization has been completed (step SA1).

In the determination process in step SA1, for example, the folder generation unit 481 uses a folder named “library” (see FIG. 4; hereinafter referred to as “library folder”) LF in a predetermined hierarchy in the file system managed by the OS. Is already generated, and if it has been generated, it is determined that initialization has been completed. The library folder LF is a work folder where the user writes data and the like. In the present embodiment, the folder generation unit 481 determines whether or not the library folder LF has been generated immediately below the root directory indicating the storage device 2 (that is, immediately below the C drive).
Alternatively, it is determined whether or not the information indicating that the initial setting has been completed is stored in the storage device 2 (for example, the registry area) in the determination process of step SA1. It is good also as a process which determines with having been set.
If it is determined in step SA1 that the initial setting has been completed, the CPU 48 ends the startup process.

FIG. 4 is a diagram illustrating a state in which the library folder LF is generated, and FIG. 5 is a diagram illustrating a state in which the category folder CF is generated.
On the other hand, if it is determined that the initial setting has not been completed, the CPU 48 performs initial setting (step SA2). For example, the folder generation unit 481 generates the library folder LF in a predetermined hierarchy as shown in FIG. 4, and further, the name “category01” is stored in the library folder LF as shown in the left column of FIG. The attached category folder CF is generated. This category folder CF is a folder for temporarily storing data selected by the user as data to be written to the disc (data to be recorded), and for storing management information described later. Note that the library folder LF may be generated in a hierarchy set by the user. In step SA2, information indicating that the initial setting has been completed is stored in the storage device 2.
As a result, the startup process SA ends.

Such category folders CF can be added and generated according to the user's operation. However, in the present embodiment, the number of category folders CF is limited to, for example, 16 at maximum. This is a measure that takes into account that as the number of category folders CF increases, the management of the disk on which data is recorded for each category folder CF becomes complicated. However, such a restriction may not be provided.
The name of the category folder CF can be changed by the user. For example, when the data to be recorded on the disc is classified according to type, it can be changed to names such as “moving image”, “photo”, and “document” as shown in the upper right column in FIG. Further, for example, when the user classifies the data according to the owner, it can be changed to names such as “father”, “mother”, and “child” as shown in the lower right column in FIG.

[Category folder structure]
FIG. 6 is a diagram showing a folder configuration of each category folder CF after the recording of the data to be recorded is executed a plurality of times.
When the category folder CF is generated in the category folder CF, a management folder MF named “Management” is generated as shown in FIG. When the data to be recorded is stored in the category folder CF and the data is recorded on the disc, the category folder CF corresponds to the disc on which the data is recorded and is referred to by the user. Folder DF (hereinafter referred to as “disk folder”) DF is further generated.

The name of the disc folder DF includes the name of the category folder CF in which the disc folder DF is generated, a character string indicating the disc type, and the number of the disc folder DF (that is, stored in the category folder CF). A character string concatenated with a character string indicating the number of the disk on which the data is recorded is set.
For example, if the name of the category folder CF is “Movie”, the installed disc is a Blu-ray disc, and the disc folder DF number set by the serial number is “1”, the disc to be generated “Movie LBD01” is set as the name of the folder DF. Each time the disk folder DF is generated, a character string obtained by incrementing the number by 1 is set in the name of the generated disk folder DF. Note that “L” in the name means “library”.

As described above, one disk folder DF corresponds to one disk on which data is recorded. Therefore, in FIG. 6, the category folder CF (CF1) named “Movie” has three disk folders DF (DF1 to DF3) named “Movie LBD01”, “Movie LBD02”, and “Movie LBD03”. ) Exists in that the data stored in the category folder CF is recorded, and three discs named “Movie LBD01”, “Movie LBD02”, and “Movie LBD03” have already been generated. It shows that.

[Contents of management information]
One management information file F1 is generated in the management folder MF. In addition, when a disk folder DF is generated in the category folder CF where the management folder MF is generated, a folder information file F2 is further generated for each disk folder DF. Hereinafter, information recorded in the files F1 and F2 is referred to as management information.
The management information file F1 includes information indicating the name of each category folder CF in the library folder LF, the name of the disk folder DF in each category folder, and the directory structure of each of the folders CF and DF and the management folder MF. Contains folder configuration information. That is, the folder configuration information includes information indicating the folder configuration below the library folder LF.

Such a management information file F1 is generated in each management folder MF in each category folder CF, but the folder configuration information of each management information file F1 is the same. For this reason, for example, when a category folder CF under the library folder LF is added, changed, or deleted, and when a disk folder DF in the category folder CF is added, changed, or deleted, it is provided in each category folder CF. The contents of the management information file F1 are updated.

In the folder information file F2, information indicating data recorded on the disc further corresponding to the disc folder DF corresponding to the folder information file F2 is recorded.
Specifically, in FIG. 6, the folder information file F2 indicated as “moving image LBD01 information file” in the category folder CF1 corresponds to the disk folder DF1 named “moving image LBD01” and “ Information indicating the data recorded on the disk named “MOVIE LBD01” is recorded. Similarly, information indicating the data recorded on the disc corresponding to the disc folder DF2 is recorded in the folder information file F2 named “moving image LBD02 information file”.
Examples of information recorded in the folder information file F2 include the directory configuration, name, size, creation date / time, update date / time, and date / time recorded on the disc, of data (folders and files) recorded on the corresponding disc. Can be mentioned.

[Processing during data recording]
Next, a data recording process executed when data is recorded on the disc will be described.
When recording data to be recorded on a disc, it is necessary to specify the data to be recorded for the category folder CF. Such designation of data is performed by storing the data in the category folder CF in the runtime screen (see FIG. 11) by an operation such as drag and drop, for example. If the stored data is a shortcut file, data whose location is specified by the shortcut file is a recording target.
Here, in the present embodiment, the runtime screen is not always displayed during the execution of the data recording program, but is displayed according to a user operation. This is because the data recording program is a resident program that is executed when the OS is started, and displays a runtime screen as necessary. However, the present invention is not limited to this, and a data recording program may be executed in accordance with a user operation, and a runtime screen may be displayed along with the data recording program.

Then, the designated data to be recorded is written and stored in the corresponding category folder CF by the data writing means 483, and when a predetermined condition is satisfied, the data recording process is executed in the background. The
Here, when a predetermined condition is satisfied, for example, when an operation for executing recording on a disc is performed by a user, a latest disc or a new disc (unrecorded disc) described later is loaded. Or a case where the current time has reached a preset time.
In the following description, a case where a user operation is performed and a data recording process is executed will be described. Note that the category folder CF in which the recording target data is stored is referred to as a target category folder CF.

FIG. 7 is a flowchart showing the data recording process SB.
In the data recording process SB, as shown in FIG. 7, first, the record enable / disable determining unit 484 determines whether or not a disk is loaded in the disk device 3 (step SB1).
If it is determined in step SB1 that the disk is not loaded, the CPU 48 waits until a disk is loaded.

On the other hand, if it is determined in step SB1 that the disc is loaded, the record availability determination unit 484 determines whether the disc is a disc capable of recording data to be recorded in the target category folder CF. Determine (step SB2).
The recordable disc here refers to the newest disc (hereinafter may be abbreviated as “latest disc”) or a new disc (blank disc) among discs in which data of the target category folder has been recorded in the past. Point to. Even if it is a new disc, a disc that is determined not to be a recordable disc in the determination process in step SB5 described later is treated as a non-recordable disc.

As will be described in detail later, the disc on which data is recorded in the recording process SD included in the data recording process SB includes the management information file F1 including information indicating the folder structure in the target category folder CF. The folder information file F2 stored in the target category folder CF is written. For this reason, for example, by comparing the management information indicated by the file F2 stored in the target category folder CF with the management information indicated by each file F2 recorded on the disc, the loaded disc is the latest. It can be determined whether or not it is a disk.

If it is determined in the determination process of step SB2 that the loaded disk is not a disk capable of recording data to be recorded, the CPU 48 returns the process to step SB1 and waits for the loading of the recordable disk.
On the other hand, if it is determined in the determination process that the loaded disk is a disk capable of recording data to be recorded, the recording control unit 486 determines whether or not the disk is a new disk. (Step SB3).
If it is determined in step SB3 that the loaded disk is not a new disk (that is, the latest disk), the CPU 48 shifts the process to the recording process SD.

On the other hand, if it is determined in the determination process of step SB3 that the loaded disk is a new disk, the display control means 482 displays "Do you want to use this disk for recording category folder data?" And a selection screen including an option for selecting one of “target category folder name” (which may be plural) and “no” is displayed (step SB4).
Based on the item selected on this selection screen, the record enable / disable determining unit 484 determines whether the data to be recorded can be recorded on a new disc (step SB5).

If it is determined in the determination process of step SB5 that data is not recorded on the loaded new disc, the currently loaded new disc is stored as a non-recordable disc until the disc is removed. Then, the CPU 48 shifts the processing to step SB1 and waits for the mounting of a recordable disc.
On the other hand, if it is determined in the determination process of step SB5 that data is to be recorded on the loaded new disk, the CPU 48 shifts the process to the registration process SC. The registration process SC will be described in detail later.

When it is determined in the determination process of step SB3 that the loaded disk is not a new disk, or when the registration process SC is completed, the CPU 48 executes the recording process SD. By this recording process SD, data is recorded on the loaded disc. The recording process SD will be described in detail later.
Then, after the recording process SD ends, the recording control unit 486 determines whether or not all of the data designated by the user has been recorded on the disc (step SB6).

If it is determined in step SB6 that there is data not recorded on the disc, the CPU 48 shifts the processing to step SB1 and waits for a new disc to be mounted.
On the other hand, if it is determined in the determination process of step SB6 that all the designated data has been recorded on the disc, the data recording process SB is terminated.

[registration process]
FIG. 8 is a flowchart showing the registration process SC.
The registration process SC is a process for registering a new disk as the latest disk.
In the registration process SC, as shown in FIG. 8, first, the folder generation unit 481 generates the disk folder DF named as described above in the target category folder CF (step SC1).

Next, the management information generation means 487 generates management information (step SC2).
Specifically, the management information generating unit 487 generates folder configuration information of a layer below the library folder LF with the new disk folder DF being added in step SC1. As described above, this folder configuration information is information recorded in the management information file F1. Further, the management information generating unit 487 generates information indicating data to be recorded on the disk, that is, information recorded in the folder information file F2. However, since data is not recorded on the loaded disc at the present time, it is generated without recording data.

Thereafter, the recording control means 486 records the management information generated in step SC2 on a new disc (step SC3). As a result, the disk becomes the latest disk.
Here, the recording control unit 486 sets the volume name (volume label) related to the name of the category folder CF or the disk folder DF to the disk, and records the generated management information. For example, when the name of the target category folder CF is “Category01” and the first disc related to the category folder CF, the volume name of the disc is set to “LBD_Category01_Disc001”. Further, when the name of the disk folder DF corresponding to the disk is “moving image LBD01”, the volume name may be the same as the name. Information indicating the relationship between such a volume name and the corresponding disk folder DF is recorded in the management information file F1 stored in the management folder MF.

Then, the management information generation unit 487 updates the contents of the management information file F1 and the folder information file F2 stored in the management folder MF of the storage device 2 with the generated management information (step SC4).
Thus, the registration process SC ends.

FIG. 9 is a flowchart showing the recording process SD.
The recording process SD is a process for recording data to be recorded on a disc.
In this recording process SD, as shown in FIG. 9, first, the data extraction unit 485 acquires the free capacity (capacity in which data can be recorded) of the loaded disc, and the data to be recorded (designated by the shortcut file). Data having a size that fits in the free space is extracted (step SD1). At this time, if the total amount of data to be recorded is less than the free space, all the data to be recorded is extracted by the data extraction unit 485. If the total amount of data to be recorded exceeds the free space, the user can select data extracted from the data to be recorded as data to be recorded on the loaded disc. Good.

In step SD1, if data has already been recorded on the loaded disc, the data extraction means 485 determines whether a folder and file having the same name as the data exists in the data to be recorded. If a folder and a file having the same name exist, the data extraction unit 485 executes data extraction by a method selected in advance for the folder and file. As such a method, any one of “not record”, “record with another name”, and “overwrite” can be cited.
Data for which “not record” is selected is not extracted as data to be recorded, and for data for which “record with another name” is selected, the data is changed after the name is changed. Extracted. Data for which “overwrite” is selected is extracted as data to be recorded, and the same name data recorded on the disc is overwritten.

Next, the recording permission / inhibition determining means 484 determines whether or not data reading and writing by the storage device 2 are frequently performed (step SD2).
When it is determined in the determination process of step SD2 that data reading and writing are frequently occurring, the record availability determination unit 484 determines that the frequency of data reading and writing falls below a predetermined threshold. The determination process is repeated. When the storage device 2 frequently reads and writes data, if the recording process is performed, access to the storage device 2 is further increased, and a foreground processing delay occurs. For this reason, the foreground process is prevented from being affected by waiting for the execution of the recording process SD performed in the background.
In this embodiment, the access frequency of the storage device 2 is determined at the start of recording. However, monitoring is also performed during data recording on the disk, and it is determined that the access frequency exceeds the threshold value. The recording may be interrupted at a point in time. Further, the same processing may be performed during the execution of the data extraction processing (step SD1 described above) in which access to the recording device 2 occurs frequently.

On the other hand, if it is determined in step SD2 that the reading and writing of data does not occur frequently, the recording control means 486 outputs the extracted data to the disk device 3, and the data is recorded on the disk. (Step SD3).
Next, the management information generation unit 487 generates the above-described management information (step SD4).
Specifically, the management information generation unit 487 generates folder configuration information in a layer below the current library folder LF. As described above, this folder configuration information is information recorded in the management information file F1. Further, the management information generating unit 487 generates information indicating data recorded on the disc, that is, information recorded in the folder information file F2.

Then, the recording control means 486 records the management information generated in step SD4 on the disc on which the recording target data is recorded (step SD5). When management information is already recorded on the disc, the management information is overwritten with the management information generated in step SD4.

Further, the management information generation means 487 updates the contents of the management information file F1 and the folder information file F2 stored in the management folder MF with the generated management information (step SD6). For example, if the folder information file F2 corresponding to the corresponding disk folder DF already exists, the management information generating unit 487 adds information indicating the recorded data to the contents of the folder information file F2. Then, the contents of the folder information file F2 are updated.

Thereafter, the recording control means 486 deletes the data extracted in step SC1 and recorded on the disc from the target category folder CF (step SD7). If the shortcut file is stored in the target category folder CF, the shortcut file is deleted instead of the data specified by the shortcut file. For this reason, the data specified by the shortcut file is not deleted.
Further, the display control means 482 displays the name of the disc folder DF corresponding to the recorded disc, and a message for entering the name and storing the disc (step SD8). At this time, if data to be recorded remains in the target category folder CF, this is displayed.

Thus, the recording process ends. If it is determined in the determination process in step SB6 that all the designated data has been recorded on the disc, the data recording process SB is terminated.
In the data recording timeline SB, data that is not recorded on the disc by being selected by the user or the like remains stored in the category folder CF, and the reason why the data is not recorded. Is recorded as a log in the management folder MF of the target category folder CF.

[Information display processing]
Next, processing when the disk folder DF is opened and a runtime screen will be described.
FIG. 10 is a flowchart showing the information display process SE. FIG. 11 is a diagram illustrating an example of the reference area RR included in the screen when the data recording program is executed. FIG. 11 shows the reference area RR in a state where the disc folder DF3 named “moving image LBD03” is opened in the category folder CF1.
When an operation for opening the runtime screen is performed during the execution of the data recording program, the information display process SE shown in FIG. 10 is executed, whereby the runtime screen including the reference region RR shown in FIG. 11 is displayed. . The reference area RR includes a hierarchical display area RR1 located on the left side and a detailed display area RR2 located on the right side.

Specifically, in the information display process SE, first, the display control means 482 reads the management information file F1 generated in the management folder MF of any category folder CF (step SE1), and the category in the library folder LF is read. An image indicating the folder CF is displayed in the hierarchical display area RR1 (step SE2).
In this hierarchy display area RR1, all category folders CF in the library folder LF and disk folders DF generated in the category folder CF selected by the user are displayed by hierarchy. By specifying data to be recorded in this category folder CF by a drag-and-drop operation, a path specifying operation, or the like, the above-described data recording process SB can be executed. Note that the management folder MF is not displayed in the hierarchy display area RR1.

After step SE2, the display control means 482 determines whether any of the displayed disk folders DF has been selected by the user (step SE3).
If it is determined in step SE3 that the disk folder DF is not selected, the display control unit 482 repeatedly executes the determination process in step SE3. Note that when an operation for closing the runtime screen is performed, the runtime screen is closed, and when an ending operation is performed, the data recording program ends.

On the other hand, if it is determined in step SE3 that the disc folder DF has been selected, the display control means 482 reads the folder information file F2 corresponding to the selected disc folder DF (step SE4).
Then, the display control means 482 displays information indicating data recorded on a disc corresponding to the selected disc folder DF (hereinafter also referred to as “corresponding disc”) based on the contents of the folder information file F2. It is displayed in the detail display area RR2 (step SE5).

In the detail display area RR2, information indicating data recorded on the corresponding disc is displayed as shown in FIG.
For example, when the disk folder DF3 named “Movie LBD03” is selected, the display control unit 482 displays the folder information file named “Movie LBD03 information file” in the management folder MF located in the same hierarchy. Read F2. Then, the display control means 482 displays information indicating the data recorded on the disc corresponding to the disc folder DF3 in the detailed display area RR2 based on the contents of the folder information file F2.

The detailed display area RR2 in FIG. 11 displays the names of folders and files, the update date and time, and the recording date and time. By scrolling the detailed display area RR2 left and right, the size and creation of the folder and file are displayed. The date and time can also be confirmed.
When the folder displayed in the detail display area RR2 is selected, information indicating folders and files in the folder is further displayed.
In such a disk folder DF, as described above, no data is actually stored. That is, information displayed in the detailed display area RR2 when the disk folder DF is selected is virtually displayed by the information display process SD.

Thereafter, the data reading means 488 determines whether or not an operation for executing the file displayed in the detail display area RR2 has been performed (step SE6).
If it is determined in step SE6 that the operation for executing the displayed file has been performed, the data reading unit 488 determines whether or not a corresponding disk is loaded (step SE7).
In the determination process of step SE7, for example, the data reading unit 488 compares the name of the selected disk folder DF with the volume name of the mounted disk, or is the same as the disk folder DF. By comparing the management information recorded in the management folder MF in the hierarchy with the management information recorded in the loaded disc, it is determined whether or not the disc corresponding to the disc folder DF is loaded. .

If it is determined in step SE7 that the corresponding disk is not loaded, the display control means 482 displays a message indicating that the corresponding disk needs to be inserted (step SE8). At this time, the volume name and number of the corresponding disk, the name of the selected disk folder DF, and the like may be displayed together.
On the other hand, if it is determined in step SE7 that the corresponding disk is mounted, the data reading unit 488 reads the corresponding file from the disk and executes the file (step SE9). Thereafter, the CPU 48 returns the process to step SE6.

If it is determined in step SE6 that the operation for executing the displayed file has not been performed, the data reading means 488 determines whether or not an operation for closing the runtime screen has been performed (step SE10).
If it is determined in step SE10 that the operation is not performed, the CPU 48 returns the process to step SE6.
On the other hand, if it is determined in step SE10 that the operation has been performed, the CPU 48 ends the information display process SD.
As described above, since actual data is not stored in the disk folder DF, virtual files in the folder DF cannot be directly executed without going through the execution screen of the data recording program. It is configured.

[Rebuild process]
FIG. 12 is a flowchart showing the reconstruction process SF.
The data recording apparatus 10 can reconstruct the folder structure of the library folder LF by executing the reconstruction process SF shown in FIG. 12 after mounting the disk on which the data is recorded. Such a reconstruction process SF is performed, for example, when a data recording program is newly executed by another data recording apparatus 10.
In the reconstruction process SF, first, the reconstruction unit 489 reads management information from the loaded disk (step SF1).
Thereafter, the reconstruction unit 489 generates a category folder CF in the library folder LF based on the folder configuration information included in the read management information (step SF2). Then, the reconstruction unit 489 generates a management folder MF in the category folder CF (step SF3).

Thereafter, the reconstruction unit 489 generates a disk folder DF having a name indicated by the read management information in the category folder CF corresponding to the loaded disk (step SF4). The category folder CF to which the mounted disc corresponds can be determined based on, for example, the volume name of the disc and management information recorded on the disc.

Then, the reconstruction unit 489 saves the management information file F1 among the read management information in the management folder MF of each category folder CF, and stores the folder information file F2 in the category folder CF corresponding to the disc. Save in the management folder MF (step SF5).
Thus, the reconstruction process SF ends.

In such a reconstruction process SF, a folder below the library folder LF is generated based on the management information recorded on the disk, so that the disk is required to be the latest disk. This is because when the folder configuration is reconstructed based on the management information recorded on the old disc that is not the latest disc, only the folder configuration at the time when the management information is recorded can be reproduced.
On the other hand, by using the latest disk, the folder structure in the library folder LF can be reproduced.

In the reconstruction process SF in the present embodiment, the disk folder DF is generated only in the category folder CF corresponding to the loaded disk, and the folder information file F2 is stored in the management folder MF of the category folder CF. However, the present invention is not limited to this, and if the folder information files F2 of all category folders CF in the library folder LF are recorded on the disc, the disk folders DF and folder information files F2 of all category folders CF are reconstructed. Is possible.
However, if all these information is recorded on the disc, the recording capacity of the disc is reduced. Therefore, in the present embodiment, as described above, the folder information file F2 to be recorded is limited, and the reconstructed disc folder DF is restricted.

[Search processing]
FIG. 13 is a flowchart showing the search process SG.
In the above data recording processing SB, data recorded in the disc among the data stored in the category folder CF is automatically deleted from the category folder CF. Therefore, when searching for the location of the data, the OS Cannot use the search function. On the other hand, the data recording apparatus 10 that is executing the data recording program can execute a search process SG for searching for the location of the recorded data.
In this search process SG, as shown in FIG. 13, first, the data search means 490 acquires the search conditions input by the user (step SG1). As such a search condition, a condition corresponding to information recorded in the folder information file F2 (the above-described data name, size, creation date / time, update date / time and recording date / time) can be mentioned.

Further, the data search means 490 reads the management information recorded in the management folder MF of each category folder CF (step SG2).
Next, the data search means 490 compares the read management information with the acquired search condition, and extracts data that matches the search condition (step SG3).
Thereafter, the data search means 490 further extracts information indicating the extracted data, the names of the category folder CF and the disk folder DF indicating the location of the data, and the names of the disks corresponding to the disk folder DF. Then, the display control means 482 displays these pieces of information as search results (step SG4).
As a result, the user can grasp which disk folder DF of the data to be searched is opened to obtain information on the data and on which disk the data is recorded.

[Effects of First Embodiment]
According to the data recording system 1 according to the present embodiment described above, the following operational effects can be obtained.
(1) In the data recording system 1, the recording control unit 486 deletes data recorded on a disc that is a kind of removable media from data to be recorded stored in the category folder CF. According to this, since the data recorded on the disk is deleted from the storage device 2, it is possible to suppress an unnecessary increase in the free capacity of the storage device 2. In particular, when data to be recorded is stored in the category folder CF by movement, the free space of the storage device 2 can be increased by deleting the data.

(2) The folder generation means 481 generates a category folder CF in the library folder LF. The data to be recorded is stored in the category folder CF, and a disc on which the data to be recorded is recorded is generated for each category folder CF. According to this, since a disk is generated for each category of the data, it is possible to easily manage the data and the disk.

(3) Folder configuration information is recorded on the disc together with data to be recorded. Then, the reconstructing unit 489 can reconstruct the folder structure based on the folder structure information in the newly generated library folder LF by executing the restructuring process SF. Therefore, when the new storage device 2 is mounted on the data recording device 10 or when the data recording device 10 itself is newly provided, the folder structure of the library folder LF used in the past can be reproduced.

(4) The management information generating unit 487 generates management information indicating data recorded on the disc, and the management information is recorded on the disc on which the data is recorded. At this time, all the folder information files F2 stored in the management folder MF of the target category folder CF are recorded on the disc. Then, the reconstruction unit 489 stores the management information read from the disk in the management folder MF of the corresponding category folder CF when reconstructing the folder structure of the library folder LF. According to this, the information indicating the data recorded on the disc from the category folder CF including the data previously saved in the category folder CF is saved in the storage device 2. Therefore, the folder structure of the latest library folder LF and the state of the category folder CF can be reproduced.

(5) When it is determined by the recordability determination means 484 that the disk loaded in the disk device 3 is the latest disk or a new disk (excluding non-recordable disks), the recording control means 486 The data to be recorded is recorded on the disc.
Here, when the folder configuration in the library folder LF (including the lower folders of the category folder CF) is changed, the folder configuration information included in the management information is changed. That is, when the number of discs on which data is recorded increases, the disc folder DF increases, the folder configuration is changed, and the folder configuration information is also changed. Therefore, when data is recorded on a disc that is not a new disc and not the latest disc, and the reconstruction process SE using the disc is performed, the latest folder configuration and management information (files F1, F2) are stored. ) Cannot be rebuilt.
On the other hand, by making it possible to record data only on a new disc or the latest disc, the folder configuration and management information of the latest library folder can be appropriately reproduced in the new library folder LF.

(6) The display control means 482 refers to the folder information file F2 stored in the management folder MF of the category folder CF, and corresponds to the file F2 and is recorded on the disk corresponding to the disk folder DF. The information indicating is displayed. According to this, the data recorded on the disc can be confirmed without mounting the disc. Thereby, the usability of the data recording system 1 can be improved.

(7) When the disk folder DF located in the category folder CF is selected on the data recording program execution screen, the display control means 482 displays information indicating data recorded on the disk corresponding to the disk folder DF. It is displayed in the detail display area RR2. According to this, since the recorded data is displayed by being classified for each disk, it is possible to easily grasp which data is recorded on which disk.

(8) Information for identifying the disk corresponding to the disk folder DF (for example, the name of the corresponding disk folder DF, the disk number, and the volume name) is stored in the management information file F1 in which a part of the management information is recorded. Is recorded. According to this, by displaying the information by the display control means 482, it is possible to easily grasp on which disk the data desired by the user is recorded.

(9) When the user sets the data search condition, the data search means 490 refers to the management information and searches for data that matches the search condition, and the display control means 482 displays the search result. Let According to this, it is possible to record user-desired data on which disk without performing an operation of selecting each disk folder DF and displaying information indicating data recorded on the disk corresponding to the disk folder DF. You can easily grasp what is being done.

(10) The recording control means 486 records data to be recorded on the disc when an operation for recording data is performed by the user. According to this, when there are a plurality of data (folders and files) to be recorded, it is not necessary to perform the operation of saving the data in the category folder CF at a time, and the data can be recorded on the disc at a timing desired by the user. Can be implemented. As described above, the recording control unit 486 stores the data to be recorded in the category folder CF, and when the latest disk or a new disk is loaded in the disk device 3 or is set in advance. The recording target data may be recorded on the disc when the current time reaches the time. In the former case, if the disc is loaded, the data can be automatically recorded on the disc when the data is stored in the category folder CF. In the latter case, data can be automatically recorded without the user being aware of it.
