摘要:
A magneto-optical disc recording and/or reproducing apparatus comprises a disc cartridge loading portion (1) on which a disc cartridge (201) housing a magneto-optical disc (202) is loaded; a disc rotary drive means (2) for rotating the magneto-optical disc (202); an optical pickup (4) which is moved in a radial direction of the magneto-optical disc (202) for recording and/or reproducing informational signals on and from the magneto-optical disc (202); magnetic field generating means (5) which is disposed in a position opposite to the optical pickup (4) with respect to the magneto-optical disc (202) and is moved in a radial direction of the magneto-optical disc in synchronization with the movement of the optical pickup (4) in a radial direction of the magneto-optical disc (202) for recording informational signals on the magneto-optical disc together with the optical pickup (4); lifting means (21-24) for moving said magnetic field generating means (5) toward and away from the surface of the magneto-optical disc (202) perpendicular thereto; loading means for loading said disc cartridge upon said cartridge loading portion (1) and for loading the magneto-optical disc (202) housed in the disc cartridge (201) upon said disc rotary drive means (2), whereby said magnetic field generating means (5) is moved from a position remote from the magneto-optical disc (202) to a position close to the magneto-optical disc (202) by said lifting means (23) in association with the loading operation of said disc cartridge (201) upon said cartridge loading portion (1) by said loading means.
