发明名称 Sliding type magnetic head for magneto-optical recording
摘要 A magnetic head for magneto-optical recording comprises a head body (32) having a sliding portion (37) which causes a head element to come in sliding contact with a magneto-optical disc (1). The sliding portion (37) is disposed on an inner periphery of the magneto-optical disc (1) relative to a central magnetic pole core (14a) of the head element so that, even when the central magnetic pole core 14a is located at an outer peripheral point (A) of the magneto-optical disc (1), the sliding portion (37) can be prevented from hitting a bump portion formed on the outer periphery of the magneto-optical disc (1). Thus, in the sliding type magnetic head for magneto-optical recording, a utilization factor of a reliable recording and reproducing region of the magneto-optical disc (1) can be improved.
