2. Description of the Related Art Digital audio tape deck TO
The handling of C character information is defined by the subcode format of the digital audio tape deck. The outline of this format is to record character information using a pack area in a subcode, and there are the following two types.

[0003] (1) is character information in the TOC pack,
It is written in the head start ID (S-ID) portion (normal program number (PNO) = 1) on the magnetic tape, and can collectively record character information of the entire magnetic tape and character information of each music. (2) is a character (character pack) for each song, and each song head (S
-ID) portion or one that can be recorded continuously, and can record character information for the song.

As described above, in the related art, there is a type in which a character pack is provided for each song, and this character information is displayed when an S-ID cueing instruction is issued.

[0005] In a digital audio tape deck capable of recording, reproducing and operating TOC character information, in the case of a self-recording magnetic tape (user tape), the Technical Report of the Electronic Industries Association of Japan (EIAJ CPR-2302).

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments. FIG.
FIG. 2 is a block diagram showing a configuration of an embodiment of the present invention.

An analog signal for recording is input to an A / D converter 1 and converted into digital data, and the converted digital data is sent to a signal processing circuit 2. The signal processing circuit 2 which has received the digital data performs predetermined signal processing such as addition and modulation of an error correction code, and together with the sub-code information such as S-ID and character information input from the key input device 9, the RF amplifier. The signal is sent to the digital audio tape deck 5 and amplified on the magnetic tape via the magnetic head in the mechanism 4 of the digital audio tape deck.

When a reproduction instruction is received, the signal recorded on the magnetic tape is picked up by the magnetic head in the mechanism 4 of the digital audio tape deck and transmitted to the RF amplifier 5 for amplification. The amplified signal is sent to the signal processing circuit 2, which performs predetermined signal processing such as demodulation and error correction in the signal processing circuit 2. The signal-processed reproduced digital data is sent to the D / A converter 3. Convert to analog signal and output.

The reproduced subcode information is sent to the control microcomputer 7 and displayed on the display device 10 based on each information.

On the other hand, the servo circuit 6 controls the drum in the mechanism 4 of the digital audio tape deck under the control of the control microcomputer 7 in accordance with instructions such as recording, reproduction, fast forward and rewind set by the key input device 9. Each motor such as a motor and a capstan motor is driven.

On the other hand, the memory 8 temporarily stores information such as TOC character information input by the key input device 9,
As in the case of the input analog signal, it is read out for recording in the subcode area on the magnetic tape. Further, information such as TOC character information read from a magnetic tape at the time of reproduction is temporarily stored and read for display or the like.

Here, the control microcomputer 7 reads out all the TOC information corresponding to the head start ID on the magnetic tape read from the magnetic tape and stores the TOC information in the memory 8. The character information corresponding to the music number of the reproduced music is determined and stored in the memory 8.
And reading means 7-2 for converting the read character information into character information for display and sending the converted character information to the display device 10.

In this embodiment configured as described above, at the time of reproduction, the TO
All the C information is read from the magnetic tape by the magnetic head under the control of the control microcomputer 7 and stored in the memory 8 by the storage means 7-1 of the control microcomputer 7.

From the TOC information, the position of the S-ID in the entire magnetic tape, the character information corresponding to the PNO, and the like are known.
The character information corresponding to NO is read by the reading means 7-2 under the control of the control microcomputer 7, and the read character information is converted by the conversion means 7-3 of the control microcomputer 7 into the display character information. And transmitted to the display device 10. In the display device 10 that has received the character information for display, the character corresponding to the character information read from the memory 8 is displayed.
Will be displayed.

When the user designates the PNO with the key input device 10, the control microcomputer 7 determines that the PNO has been specified, and the key input device 10 is controlled under the control of the control microcomputer 7.
The character information corresponding to the PNO specified by is read from the memory 8 and the character corresponding to the character information is displayed on the display device 10.

Further, during the renumbering operation, the subcode information on each S-ID is rewritten, and at the same time, the corresponding character information is read from the memory 8 under the control of the control microcomputer 7. By recording the character pack as a character pack on a magnetic tape, the character pack can be recorded, reproduced and operated as a result. The magnetic tape on which the character pack is recorded as described above can display at least the display of the character corresponding to the character information of the currently reproduced song on the display device 10 without performing the operation of reading the TOC information. .

When the TOC character information is set by the user using the key input device 9, the same part of the set character information corresponding to each music is also recorded on the S-ID of the music. As a result, the S
-The character information recorded on the ID may be read, and the character corresponding to the read character information may be displayed.
