ABSTRACT:
An A/V signal region for A/V signals and an audio signal region for only audio signals of the A/V signals are disposed on a record medium of a HDD. When the audio signals and the video signals of the A/V signals are independently edited, the A/V signal region is sought from the audio signal region. Each channel of the audio signals in the audio signal region is sought. Thereafter, the A/V signal region is sought. Since the number of sectors of the audio signals is smaller than that of the video signals and thereby the track width of the audio signal region is smaller than that of the A/V signal region, the seek distance in the region is small. Thus, the seek time can be decreased. When the edit point of an audio signal is the same as the edit point of a video signal or when an A/V signal is successively reproduced, only the A/V signal region is used. Thus, the A/V signal can be reproduced at very high speed.
