The title or broadcast station name is sequentially and temporarily stored, and is controlled to be recorded on a disk.

Since the recording start track is 3 in S13, it is checked in S14 whether the title of the third track has been input. Since the title of the third track has not been input, the process proceeds to S16. Since the third track is not the track at the end of recording in S16, the process proceeds to S17 and the track is incremented to the fourth track. Returning again to S14, it is checked whether the title of the fourth track has been input.
Since the title of the fourth track has been input, the process proceeds to S15, and the title stored in the title memory 14 in the fourth track is transferred to the disk recording / reproducing circuit 8 as the title of the unit information. Thereafter, when the last sixth track is obtained by repeating S14 to S17, the process proceeds to S18.

Since the recording start track is 3 in S18, it is checked in S19 whether the title of the third track has been input. Since the title of the third track has not been input, the process proceeds to S20, where the broadcast station name selected in the broadcast station name memory for the third track is transferred to the disc recording / reproducing circuit as the title of the unit information, and the process proceeds to S21. 3 in S21
Since the track No. is not the track at the end of recording, S2
The process moves to 2 and the track is incremented to the 4th track.

Returning to step S19, it is checked whether the title of track 4 has been input. Since the title of the fourth track has been input, the process proceeds to S21. After that, by repeating steps S19 to S22, if the final sixth track is reached, step S23 is executed.
Then, the contents of the UTOC in the buffer memory 9 are recorded on the disk. As described above, according to the recording / reproducing apparatus of the third embodiment, since only the input title is stored in the title memory, the memory for the name of the broadcast station to be recorded can be saved. Since the management means subtracts only the number of characters of the input title from the free area at the start of recording, it is possible to allocate all the capacity of the free area to the input title, and it is possible to allocate more titles. You will be able to enter. However, since the title of each unit information of the recorded disc is recorded with priority given to the input title, if the title recording area of the disc becomes full during title recording, the track in which no title is input Does not record the broadcast station name as the title of the unit information.

Note that the broadcast station memory in the above description is
The broadcast station name may be registered in advance, or the user may be allowed to freely register the broadcast station name later. In the above description, the MD has been described as a recording medium for recording the unit information of the broadcast program and the title of the unit information. However, the information of such a broadcast program is recorded, and the information of the divided information is recorded. If the recording medium has an area for recording a title, a DVD
Other recording media such as disks and tapes may be used.
