Abstract

PROBLEM TO BE SOLVED: To perform a useful display at the time of track editing by displaying information of a track name, corresponding to a selected track number. SOLUTION: When a track of an editing object is selected by a key matrix 7, a TNO is selected and displayed on the display 8 by a system controller 5, based on key input information from the matrix 7. At this time, track name character string information, corresponding to the selected TNO, is read out of the memory 6 in a UTOC area sector information stored in the memory 6, and is simultaneously displayed together with the TNO on the display 8 by the system controller 5. Thus, since the discrimination of a track to be the editing object can be performed not only by the value of that TNO but confirming the relevant track name character string information recorded in the UTOC area, operational convenience is enhanced.

Reference numeral 7 denotes a key matrix which receives an instruction from a user's key operation and controls the system controller 5 to control normal reproduction, recording, pause, stop, search, etc., read and write to the memory 6, request display on the display 8, etc. Perform

Next, the operation based on the above configuration will be described.
UTOC of sector format used in MD
In the area sector 0, management information of recorded music data, TNO, etc. are recorded, and in the UTOC area sector 1, character information of a disc / track name, etc. are recorded. Therefore, when reproducing the MD, the music data is reproduced based on the address information of the program area in which the music data for each TNO described in the UTOC area sector 0 is recorded, and at the same time, the music data is reproduced in the UTOC area sector 1. The contents can be displayed on the display 8 based on the information of the track name and the disc name corresponding to each TNO.

On the other hand, at the time of recording on the MD, the start and end address information of the music information recorded in the program area is recorded in the UTOC area sector 0 in association with the TNO, and the input disc track name information is recorded in the UTOC. It is recorded in the area sector 1 in association with TNO.
