ABSTRACT:
Two magnetic heads having different azimuth angles are mounted on a cylindrical rotary drum. The data is recorded on the magnetic tape by means of the magnetic heads mounted on the rotary drum. When recording, a frame is composed of one track formed by one magnetic head, and another track formed by the other magnetic head. The data is recorded in the unit of one frame. When reproducing, one track is read by one magnetic head, and the other track is read by the other magnetic head. Plural sets of data to compose one frame are stored in the memory, when reproducing in the normal direction, as the addresses are specified for each set of data. The data stored in the memory is read out from the memory as the addresses are specified so as to be output in a predetermined sequence. When reproducing in the reverse direction, the data stored in the memory is read out of the memory as the addresses are specified so as to be output in the reverse sequence of the output sequence of the data of reproduction in the normal direction.
