Abstract
The structure of a magnetic head for use in a disk drive has an erase core and a read/write core which are inclined to a track of a floppy disk or disket. An erase gap and a read/write gap formed in the erase core and read/write core, respectively, each is inclined by a different angle to the longitudinal axis of the magnetic head. A shield plate is interposed between the two cores for magnetically shielding them from each other. With this configuration, the magnetic head reduces crosstalk ascribable to flux picked up by the erase core from the track.
