Abstract
It is an object of the present invention to provide a data recording apparatus which is designed to allow compatability to other recording and reproducing apparatus and is capable of readily performing the additional recording or rewriting of data. Channels ch1 and ch2 are used as a channel for video data; and channels ch3 and ch4 as a channel for audio data. During the recording of video data, the channels ch3 and ch4 are made to be null. On the other hand, during the recording of audio data, the channels ch1 and ch2 are made to be null. Accordingly, the rewriting of the recorded video data or audio data as required can be easily performed. Besides, where recording is performed only on either the channels for video data or the channels for audio data, recording areas are secured for the other channels so that after-recording (additional recording) is easily performed.
