Title: Pcm recorder and reproducer
Inventor: TANAKA KUNIMARO
IPC: G11B20/18
Filed: 1980-04-23
Abstract: PURPOSE:To increase error correction ability, by re-recording the tracks and the tracks independent of the error correction and redundant section into the content without correction of error, if a multitrack reproducing voice channel signal produces the error beyond its correction capability. CONSTITUTION:Each PCM voice signal is recorded on tracks 2-1... and the error correction redundancy section forming the signals is recorded on the tracks 5-1, 5-2 independent of the track 2-1... allowing to correct the error of reproducing output up to 2 tracks. Further, the over-damping can be made without deterioration of signal by re-recording of the tracks 2-1... and tracks 5-1 and 5-2. On the other hand, if an error beyond the correction capability is produced at reproducing, the recording in the tracks 5-1 and 5-2 is rewritten into the frame synchronizing signal or content 17... in error, to block error correction. Thus, correction by mistake in error is not practiced and the capability of error correction is increased through interleaving, etc.
