ABSTRACT:
A magnetic recording/reproducing apparatus in which at least two recording and reproducing magnetic heads are mounted on a rotatable cylinder with an angular distnce of 180.degree. therebetween, wherein audio signals having undergone a pulse code modulation are recorded on record tracks slanted relative to the longitudinal direction of a magnetic tape wrapped around the rotatable cylinder. The record track is divided trackwise into a plurality of channels. The audio signals are recorded on the channel basis. The magnetic tape is transported in a forward or backward direction while recording or reproduction is conducted. The rotatable cylinder has mounted thereon a first erasing head rendered operative when the magnetic tape is transported in the forward direction and a second erasing head operative when the magnetic tape is transported in the backward direction for erasing only the audio signal of a given channel on the record track.
