摘要： A disk centering apparatus includes a disk table member and a movable member. An inner circumferential portion of the disk table member is secured to an upper portion of a motor shaft. An outer circumferential portion of a greater diameter is disposed lower than an upper surface of and concentrically with the inner circumferential portion and has an upper surface for receiving a disk thereon. Connecting portions extend radially outwardly from the inner circumferential portion. The movable member includes a supported shaft portion mounted for sliding movement on the motor shaft and disposed lower than the disk table member. A guiding portion is provided adjacent an outer surface side of the supported shaft portion and includes a guiding inclined portion formed at an upper portion thereof and a diameter greater than the inner circumference portion. The movable member is biased upwardly in a direction of the motor shaft.

摘要： A recording and/or reproducing apparatus for a magneto-optical recording medium housed within a disc cartridge. The recording and/or reproducing unit includes a magnetic head for applying a perpendicular magnetic field to the magneto-optical recording medium. A transporting unit includes a holding section for holding the inserted disc cartridge and a pair of cam members for moving the holding section in horizontal and vertical directions in a casing. The cam members are moved a first horizontal displacement as a result of insertion of the disc cartridge and set a driving unit into an operating state. The cam members cause the holding section to be moved in the horizontal direction by a second horizontal displacement of the cam members. The cam members cause the holding section to be loaded on the recording and/or reproducing unit by a third horizontal displacement continuous with the second horizontal displacement.

摘要： A recording and/or reproducing apparatus for a magneto optical recording medium housed within a disc cartridge includes a casing, a recording and/or reproducing unit, a transporting unit and a driving unit. The casing includes an opening for introducing and ejecting the disc cartridge. The recording and/or reproducing unit includes a magnetic head for applying a perpendicular magnetic field on the magneto-optical recording medium and is housed within the casing. The transporting unit loads the disc cartridge inserted via the opening on the recording and/or reproducing unit. The transporting unit includes a holding section for holding the inserted disc cartridge and a pair of cam members for moving the holding section in the horizontal direction in the casing and in the vertical direction in the casing in continuation to the movement in the horizontal direction. The driving unit causes the cam members to be moved in the horizontal direction in the casing. The cam members are moved in a first direction as a result of insertion of the disc cartridge and set the driving unit into operating states as a result of insertion of the disc cartridge. The cam members cause the holding section to be moved in the horizontal direction by a movement of the cam members in a second horizontal direction consecutive to the movement in the first horizontal direction by the driving unit. The cam members cause the holding section to be loaded on the recording and/or reproducing unit by a movement of the cam members in a third horizontal direction consecutive to the movement in the second horizontal direction by the driving unit.
