摘要： Disc recording and/or reproducing apparatus comprising: an optical pickup unit (42) movable across the inner and outer peripheries of a disc (205, 214) on which information signals are pre- recorded or are to be recorded, a magnetic head (45) facing the optical pickup unit with the disc in-between to apply an external magnetic field to the disc; a disc loading section (30) to load a disc cartridge (201, 211) rotatably housing the disc; a cartridge holder (26) removably to hold the disc cartridge (201, 211) therein, the cartridge holder (26) being supported by the disc loading section (30) for movement in a direction of shifting the disc cartridge (201, 211) towards and away from the disc loading section (30), and a magnetic head supporting member (44) arranged for movement across the inner and outer peripheries of the disc (201, 211) loaded on the disc loading section (30) along with the optical pickup unit (42), the magnetic head supporting member (44) supporting the magnetic head (45) for movement between a first position in which the magnetic head (45) is proximate to the disc (201, 211) and a second position in which the magnetic head (45) is spaced apart from the disc (201, 211).
