ABSTRACT:
In a magneto-optical recording apparatus, a magnetic head is employed so as to perform vertical, or perpendicular magnetic recording. The magnetic head is constructed of a slider and a plurality of magnetic cores symmetrically positioned with respect to an axis of a magnetic recording medium. Each of the magnetic cores includes a main core, a return path core, and a gap.
