ABSTRACT:
Disclosed is a magnetic recording/reproduction apparatus wherein a pulse corresponding to rotation of a magnetic disk is obtained by detecting a PG yoke signal as a rotational position detection index in the disk by a PG coil as a pulse detection means, recording/reproduction control is performed by a control circuit or the like as erase recording/reproduction control means operated in accordance with the pulse, erase and recording/reproduction operations of data are performed with respect to the disk by a composite magnetic head controlled by the erase recording/reproduction control means, i.e., the composite magnetic head in which an erase gap and a read/write gap are integrally provided so as to be separated from each other in the longitudinal direction of a recording track.
