Abstract
PURPOSE: To perform recording and reproducing simultaneously to facilitate phase check by supplying sound phrases of respective halves of coaxial circles of a magnetic disc alternately to plural time base change memories.
CONSTITUTION: A recording signal is supplied to time base change memories 3a and 3b alternagely after A/D conversion in 2 and is subjected to time base compression and is recorded onto magnetic disc 5 alternately. In this case, the recording signal is written onto time base change memory 6a or 6b simultaneously while the head of disc 5 scans the half circumference of a coaxial circle track, and outputs of memories 6a and 6b switched synchronously with switching of memories 3a and 3b are subjected to D/A conversion in 8 and are reproduced. Consequently, signal reproducing can be performed at the almost same time as the recording time, and the recording phrase for every half circumference can be cheked.
