Magnetic head for magneto-optical recording and magneto-optical

Abstract

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 a main magnetic pole end face of from 0.01 mm.sup.2 to 0.039 mm.sup.2. The magnetic material for the core is a Mn--Zn ferrite having a Curie temperature of not less than 140.degree. C., a permeability of not less than 200 at frequency 8 MHz at temperature 25.degree. 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 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 a maximum frequency of not less than about 8 MHz.
