ABSTRACT:
In a magnetic head apparatus that generates a strong magnetic field of magneto-optical recording or the like, a joint assembly of main and side cores is fitted into an accommodating groove formed in a ceramic slider, and a bobbin having a coil wound around it is fitted onto the main core. Further, a back core is fastened to the main and side coils. An electrical insulating layer extending along the dimension of the magnetic path is formed in the main core to divide conductive region by the sections of the main core. Thus, the eddy current generated along a dimension perpendicular to the magnetic path is suppressed, whereby the core loss is mitigated and the quantity of heat generated in the core is reduced.
