Abstract
Apparatus and method of recording and reproducing data using a disk to record musical performance data. Data related to the music and start times for each piece of music are recorded onto a table of contents section of the disk and the operation is controlled according to this data. Therefore, wasteful reproduction operation is avoided when there exists non-recorded areas between pieces of music or when a piece of music shorter than the initial piece of music is recorded overlapped thereon, enabling the music to be favorably reproduced. In carrying out the (sound) recording operation, furthermore, the non-recorded areas can quickly be found.
