Abstract
Audio signals are recorded on recording tracks of a disk shaped recording medium in a predetermined schedule for making establishment of an associated track information table easier and allowing after recording of audio signals with respect to each video signal. In addition, selective or entire erasure of video signals and associated audio signals is automatically performed when one of the recording tracks recording one of the video signals or the associated audio signals is ordered to be erased.
