Abstract
PURPOSE: To secure the rerecording of the signals with every channel by inserting the necessary signal between the different channels of the signals which are multiplied in time division in ouder to form the recording signals and then recording these signals through the rotary head.
CONSTITUTION: The audio signal of each channel undergoes the PCM modulation through A/D converters 9AW9D to obtain PCM signals SAWSD. The time axis of the PCM signal is compressed by increasing the reading clock frequency for memories 10A W10D higher than the writing frequency, and the ample signal and the synchronous signal are added to the data via mixer circuit 12 to obtain recording signal SR. This signal SR is recorded through rotary magnetic heads 3a and 3b. Thus the multi-channel signal can be recorded, furthermore enabling both erasion and rerecording for and optional among the multiple channels.
