Abstract
A helical scanning type magnetic recording and reproducing apparatus records a signal representing recording conditions on a magnetic tape when a recording is effected thereon, together with a PCM audio signal. At the time of reproduction, reproducing conditions are controlled so as to be the same as the recording conditions on the basis of the signal representing recording conditions reproduced.
