ABSTRACT:
A magnetic recording and playback apparatus using a magnetic head disposed on a rotating drum for forming oblique recording tracks in succession on a magnetic tape to record or playback serial data along the same, has a tracking control for controlling the height of the magnetic head in the direction perpendicular to the length of the recording track. A speed control is included for controlling the rotating speed of the rotating drum and/or the traveling speed of the magnetic tape in accordance with the bit transfer rate of the serial data so that the magnetic tape travels one reference track pitch while the rotating drum makes an integer number of rotations. A processor is included for compressing the serial data along the time base so that the serial data is recorded while the magnetic head scans the recording track.
