Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape recording and reproducing apparatus, and more particularly to a tape recording and reproducing apparatus that records a program index on a tape, locates the beginning of a program, and displays recorded contents.

[Conventional technology]

Conventionally, this type of tape recording/playback device does not have a program information data section recorded on the tape, so when searching for the beginning of a program, the user must manually search for the program while fast forwarding or rewinding the tape. Ta.

[Problem to be solved by the invention]

The above-mentioned conventional tape recording and reproducing apparatus records only video and audio signals and does not record program vergence, so when searching for the beginning of a program, it is necessary to search for the program manually. In addition, since the content time of the recorded program and the remaining amount of tape are not known, when additional recording is performed on the tape, it is not known whether there is enough remaining tape to record the program, and the tape cannot be used effectively. be.

[Means to solve the problem]

The tape recording and reproducing apparatus according to the present invention includes an index generating section that generates index data having a program number, a program start address, an end address, and a recording speed of the first Km of audio tracks on a tape, and converts the index data into an audio signal. a rounding index modulation section that records data, an index demodulation section that reproduces and demodulates the nine indexes, an index memory section that expands the index data, a program cueing section that cues the beginning according to the memory contents, and a program and a program display section for displaying contents.

[Effect]

In this invention, by recording a program index on a tape, it is possible to locate the beginning of the program and display the recorded contents.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of a tape recording and reproducing apparatus according to the present invention. In the figure, 1 is a tape whose tape format is shown in FIG. 2, 2 is a tape running control unit that automatically rewinds the tape 1 to the beginning when the tape 1 is set, and 3 is the audio of the tape 1. a tape recording and playback section that plays back track index data;
4 is an index demodulation unit that converts the audio signal into data;
5 is an index memory section that stores index data; 6 is a program display section that displays the contents of this index data as program information and remaining tape capacity; T is an operation section that specifies the recording button and recording program number; 8 is an index memory A program cueing section reads the contents of section 5 and instructs the drive travel control section 2 to perform fast forwarding or rewinding, 9 is an index generating section that generates index data, and 10 is this index generating section. This is an index modulation section that converts the index data generated in step 9 into an audio signal.

Note that in the tape format shown in Figure 2, 11
is a tape audio track divided into an index data section 12 and a program section 13, and this index data section 12 is located at the beginning of the tape audio track 11,
Inside is the first program signal 14. 1st starting address 15
．． First end address 16. 1st speed recording speed 17th to mth
Program number 1B, mth start address 1B, mth end address 20. It is composed of the m-th recording speed 21.

Next, the operation of the tape recording/reproducing apparatus having the above configuration will be explained. First, when the tape 1 recorded in the tape format shown in FIG. 2 is set, the tape running control section 2
automatically runs tape 1 and rewinds it to the beginning of tape 1.

Then, the tape recording and reproducing section 3 reproduces the index data of the audio track in the tape 1, and the index demodulating section 4
Output to. Therefore, the index demodulation section 4 converts this audio signal into data and transfers it to the index memory section 5. The index memory section 5 stores this index data, while the program display section 6 displays the contents of this index data as program information and tape remaining amount. Next, when recording a program, the human system reads the display contents of the program display section 6 and specifies the recording button and recording program number on the operation section 7. For example, referring to FIG. 2, if up to program number nII has been recorded, and when program number n+1 is recorded, if you specify the record button on the operation unit 7 and the program number address n+1, the program start section 8 will be stored in the index memory. It reads the contents of section 5 and instructs tape running control section 2 to fast-forward υ or rewind to the end address of the nth program, and when the cue is completed, it stops and enters a recording preparation state. Here, the program is recorded via the tape recording and reproducing section 3 according to instructions from the operating section 7. When this program recording is completed, the operation section T instructs the tape running control section 2 to rewind to the n+1 index section of the tape 1.

On the other hand, the index generator 9 generates index data and outputs it to the index modulator 10.

Therefore, this index modulation section 10 converts this index data into an audio signal and outputs it to the tape recording/reproducing section 3. The tape recording and reproducing section 3 records this audio signal on the tape 1, while storing the recorded data in the index memory section 5.

Next, when playing a program, the human system reads the display contents of the program display section 6 and inputs the υ playback button and the playback program number on the operation section 7. 8.

Therefore, the program cue section 8 reads the contents of the index memory section 5, causes the tape running control section 2 to fast forward or rewind to the start address of the read program, and when the cue completion is completed, the operation section 7 is activated. The program is then played back by the tape recording/playback unit 3 via the program.

In this way, when setting the tape, the data is developed in the index memory section 5, and when the recording is completed, the index generation section 9 operates and records, thereby locating the beginning of the program.
Content display can be realized.

〔Effect of the invention〕

As explained in detail above, according to the tape recording and reproducing apparatus according to the present invention, the program number, program start address, program end address, and recording speed are recorded as index data at the beginning of the tape audio track when program recording is completed. Furthermore, by reading the index data at the beginning of the tape audio track when the tape is set, it is possible to accurately locate the beginning of the program for the next recording or playback with a very simple operation. Additionally, by displaying the index data, you can see at a glance the recording program time, the remaining amount of tape, and the tape can be used efficiently.
