MAGNETO-OPTICAL DISK RECORDING APPARATUS

摘要

Magneto-optical recording apparatus (10) comprising an optical head (22) shiftable in the diametrical direction of a magneto-optical disc (2) and capable of irradiating a light beam onto the magneto-optical disc (2), and a magnetic head (20) disposed to be mutually opposite to the optical head (22) with the magneto-optical disc (2) interposed therebetween, and capable of applying a magnetic field to the magneto-optical disc (2) while being shifted in the diametrical direction of the magneto-optical disc, (2) wherein the magnetic head (20) is shiftable in the diametrical direction of the magneto-optical disc together with the optical head (20). The magnetic head (20) comprises an E-shaped core and a coil wound around a centre core element thereof, and the E-shaped core is so formed that the sectional length of the centre core element in one direction (y) extending toward two side elements of the core is equal to or shorter than the sectional length in the direction (x) orthogonal thereto. The magnetic head (20) is so disposed that the orthogonal direction (y) of its core is coincident with the diametrical direction of the magneto-optical disc (2).
