Abstract
A rotary head type digital signal recording and reproducing apparatus plays a magnetic tape which is pre-recorded with a time division multiplexed audio signal comprising a PCM audio data and a sub-channel signal which is time division multiplexed immediately before and after the PCM audio data for each track. When carrying out an after recording of the sub-channel signal to be reproduced in a half tape speed mode, both of the rotational speed of the two magnetic heads and the tape transport speed are set identical to those at a standard tape speed mode which has a rotational speed and the tape transport speed which are twice those of the half-speed mode.
