<p>A magnetic head for magneto-optical recording includes a slider sliding on a magneto-optical recording medium, a core made of a magnetic material and mounted to the slider, and a coil wound around the core. The core has an area of main magnetic pole end face of from 0.01 mm<2> to 0.039 mm<2>. The magnetic material for the core is a Mn-Zn ferrite having a Curie temperature of not less than 140 DEG C, a permeability of not less than 200 at frequency 8 MHz at temperature 25 DEG C, and an effective saturation magnetic flux density of not less than 4400 G. A magneto-optical recording apparatus includes an optical head for irradiating a magneto-optical recording medium with a light spot, and a magnetic head for applying a magnetic field to the magneto-optical recording medium. The magnetic head includes a slider being sliding on the magneto-optical recording medium, a core made of a magnetic material and mounted to the slider, and a coil wound around the core. Upon application of a voltage to the coil a modulation magnetic field is applied to a recording surface of the magneto-optical recording medium to record an information signal with maximum frequency of not less than about 8 MHz. <IMAGE></p> |
