Abstract
The present invention relates to an apparatus for recording a digitized signal. If a recording apparatus is switched from a recording mode to a non-recording mode and then switched from the non-recording mode to a recording mode, there is produced a portion between two records where the records are not continuous. When such a portion is reproduced, abnormal data come to be reproduced because of existence of discontinuity between the prior and subsequent data. And, if a digital audio signal is similarly recorded, it follows that an abnormal sound is generated when such a portion is reproduced. Then, by recording an anti-format signal in the discontinuous portion, the reproduction of abnormal data or generation of abnormal sound can be prevented from occurring.
