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.

Multiple core magnetic head for magneto-optical recording apparatus

A core slider for a magnetic head is disclosed, in which occurrence of the grain detachment from the slider due to microcracks produced at the fabrication of the slider is reduced by forming a hematite thin film on the surface portion of the core slider.
