DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance board for an optical disk drive for removing dust adhering to an optical head.

[0002]

2. Description of the Related Art An optical disk or a magneto-optical disk is used to record sound information, image information, computer data and programs, and the disk is set on a playback device or a playback / recording device and rotated. It is designed to receive the reflected light of the irradiated light. Since the surface of the lens body of the optical head is exposed in the internal space of the disk device, dust easily adheres to the surface, and the recording or reproduction of information is easily affected.

[0003] For this reason, conventionally, there has been proposed a method in which a brush is implanted on a substrate having substantially the same shape as a disk disk to rotate the substrate, and the brush cleans the surface of the optical head.
In such a cleaning disk of the optical head, a brush is simply implanted on the disk body, so that the apparatus side may determine that the brush is damaged and cause a reproduction error. For this reason, even if cleaning is performed normally, an error is displayed on the device side, so the user cannot judge whether the cleaning is normal or not, and a signal, music, etc. for checking the cleaning effect is recorded. It was also difficult to add value, such as doing. Even if the shape of the brush can be devised so as not to cause a reproduction error, the cleaning method during reproduction, in which the brush and lens are in contact, requires a long time and not only does not allow quick work but also overcleaning. May damage the lens.

On the other hand, there is a compact disk (hereinafter referred to as a CD) on which a check signal is recorded in order to check the performance of each device such as an amplifier or a speaker such as an AV device including the disk device. There are various check signals for adjusting the output balance between the left and right, and for checking the frequency characteristics.

[0005] A digital reproducing apparatus such as an optical disk player has a skip reproducing function. For example, if the skip button is operated during the performance of the first music piece by the music selection button, the adjacent second music piece can be quickly reproduced, and it is also possible to directly select and reproduce a distant track number. In any case, reproduction is not performed during skipping, and the lens moves to the head of the selected track number. Here, track number 1 (first song) to track number 6 (6
If a skip that secures a sufficiently large jumping space is performed, as in the case of skipping to a music piece, a cleaning member can be provided over each track having this space.
By bringing the lens into contact with the cleaning member by moving the lens during skipping, it is expected that effects such as avoidance of the reproduction error and rapid cleaning work can be obtained.

However, even in this case, there is a disadvantage that the skip is not executed unless the user forgets to perform the skip operation. In addition, although the cleaning area can be secured by arranging the cleaning member over a number of tracks, the recognition of the track number being skipped is impeded by the cleaning member, and the track number may not be skipped to the intended track number.

[0007]

SUMMARY OF THE INVENTION The present invention is based on the advantage of performing cleaning by the so-called skip operation, and it is an object of the present invention to further improve the usability and reduce the operation failure during the skip operation as much as possible. I do.

[0008]

According to the present invention , a reading area, a cleaning area D in which a cleaning member for cleaning the lens 21 of the optical head 20 is implanted in order from the inner circumference , and a check signal In the maintenance disk of the optical disk device having the recording area C, the cleaning area D is replaced with the optical disk drive.

Can be collected without causing the problem , and the usability of the user is improved . Also, the end greeting signal indicates when cleaning is completed.
By being reproduced, ensures cleaning completion to the user
Can be recognized.

[0010] The cleaning member of being formed in one track, when skip movement, the cleaning member in the checking operation of the track and track boundary of error cause and such Razz, reliable skip operation is performed.
If a skip operation is performed, the signal recorded on the board is reproduced after cleaning is completed, so a function for checking the state after cleaning by signal reproduction has been added,
Product value is improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a board body 10 according to the present invention,
It has substantially the same shape as mCD. TOC (Table of Co.) which is a reading area from the inner peripheral side
Ntents) area A, start greeting recording area B, the cleaning area D flocked member 22 is implanted as a cleaning member, the recorded check signal recording area C of the check signal, terminates greeting recording area E is different respectively It is provided independently so that it can be recognized as a single track number . Each of the areas B, D, C, and E corresponds to a track selection operation of the disk device 30, and specifically,
Correspond to the music selection buttons 1, 2, 3, and 4. In the TOC area A, the disk 10 is mounted on the disk device 30 shown in FIG.
Are recorded. When the disk 10 is set on the disk device 30, the optical head 20 in the device 30 starts reading from the TOC area A. As the disk device 30, a laser disk, a device having both of them having a reproducing function, and the like can be considered in addition to the CD player.

After reading the TOC area A, the optical head 20 moves to the greeting recording area B which is the first track,
A message that informs the user of how to handle the board 10 is reproduced.

[0013] Specifically, "Thank you for purchasing XX. This time, pressing the music selection button 3 will clean the optical head of the disc playback device used by the customer." The message is reproduced, and the user is notified of the correspondence between the music selection button 31 in the disk device 30 used by the user and the function of the board 10, and the skipping cleaning is executed by pressing the music selection button. I'm trying to get it.

Here, if the user does not operate the music selection button 31, the operation automatically shifts to the second track. The cleaning area D, which is the second track, has a sound area D1 and a silent area D2 on which a message indicating that cleaning is started is recorded.
A flocked body 22 having a width of 0.6 mm, a length of about 8 mm, and a height of about 8 mm is planted on a track on which a silent portion signal is recorded, with a radiation direction as a longitudinal direction, and a tip of the flocked body 22. Abuts on the surface of the lens 21. (FIG. 3
reference)

Since it is desirable to perform lens cleaning by jumping over the second track, the user may
In order to prevent the track from continuing to be reproduced, a message (skip prompt signal) for skipping for cleaning is recorded in the sound portion D1 on the inner peripheral side of the cleaning area D. The user is prompted by this message to select the music selection button 3 again.

In the check signal recording area C serving as the third track, a system check signal capable of judging whether or not the system is correctly connected, a high-frequency and low-frequency reproduction limit check, and the like can be provided. Signals and the like are recorded. Finally, a message indicating that the reproduction of the check signal has been completed is reproduced.

By selecting the music selection button 3, the reproduction signal recorded in the check signal recording area C, which is the third track, is reproduced by jumping over the track (second track) in the cleaning area D. The end greeting recorded in the end greeting sentence recording area E that will be the next track if left as it is
The sentence is played. Optical head 20 is in cleaning area D
When the lens 21 jumps over, the lens 21 moves in the radial direction while contacting the flocked body 22 rotating at a high speed, and the lens cleaning is completed.

The lens 21 and the flocked body 22 come into contact with each other without performing the operation of jumping the cleaning area D, and the cleaning is executed. In this case, the optical head 20
Sequentially follow the silent portion D2 of the cleaning area D, so that the cleaning time is longer than in the case of the jump.

When a user uses the maintenance panel 10 of the optical disk device having the above configuration,
First, the board 10 is set on the disk device 30. Board 1
0 is set, and if the user does nothing, the TO
First, the start greeting text recording area B of the first track is reproduced by the signal recorded in the C area A. The user selects the music selection button 31 of the disk device 30 according to the reproduction content.
Select If left as it is, cleaning for a long time is started in the cleaning area D of the second track, but a reminder signal to skip the second track, such as "press the music selection button 3", is recorded in the first track. Therefore, long-term cleaning is avoided. In addition, since the skip prompt signal is also recorded in the sound section D1 in the second track, the user can avoid the cleaning for a long time even if the user performs continuous reproduction by mistake. In any case, the skip to the third track can be executed, so that the skip prompt signal may be recorded on at least one of them.

In the selected third track, a sound for checking and the like is reproduced, and the user can perform a system check and a capability check of the AV device or the like in use.

The operation of each of the other music selection buttons is as shown in FIG. As shown in the above embodiment, according to the present invention, since the reproduction signal recording area C is provided as a separate track on the outer peripheral side of the cleaning area D, the cleaning effect of the flocked body 22 can be continuously and immediately performed. It can be confirmed by the reproduction of the file. Thus, the check signal can be used for checking the cleaning effect.

Further, the cleaning of the board surface of the check signal recording area is also simplified since there is no obstruction such as the flocked body 22 on the outer periphery. In this embodiment, the check signal always passes through the cleaning area when reproduced, so that the cleaning function is linked to the reproduction operation. (See Fig. 4)

In the above embodiment, a CD has been mainly described. However, as an optical disk, there are a laser disk, a magneto-optical disk, etc. in addition to a CD, and not only for music and video, but also for computer data and program recording. Including. In addition, as a cleaning body of the optical head, a method of generating a flow velocity of air in addition to the above-described flocked body and blowing off dust by wind pressure may be considered.
