ABSTRACT:
A magnetic recording and playback apparatus comprises a rotary drum (5) having a center of rotation inclined to the running direction of a magnetic recording tape (7), a group of first and second channel recording heads (1,3) and a group of first and second channel playback heads (2,4) mounted on an outer periphery of the rotary drum (5) at an angular interval of substantially 90 degrees, the positions of the recording and playback heads alternating along the outer periphery. The axial distance between the recording head group and the playback head group is set to a value of approximately 7/4 times the track pitch Tp of consequently formed tracks. The first and second channel recording heads alternately form first and second tracks in sequence on the magnetic recording tape, and after the second track is formed by the second recording head, a recorded signal on the first track is outputted by being traced with the first channel playback head.
