摘要： An optical disk device for correctly positioning on a turntable, an optical disk composed of two optical disks glued together, regardless of how poorly they are attached together. The device includes the turntable, on which the optical disk is placed, a disk holding part onto which a mounting hole of the optical disk is fitted, and a clamping member, which is provided on part of the circumferential surface in the disk holding part, is free to move in the radial direction of the disk holding part, and is impelled radially outward. The clamping member is formed in a mountain shape by two sloping faces and a sloping faces meet. The tip is beveled to a shape such that the tip makes a surface contact with the optical disk when the optical disk is mounted on the turntable.

摘要： In a disc apparatus using a disc as an information recording medium, a vibration caused by an uneven distribution of weight of a rotational member can be prevented. A motor for rotating a turntable of the disc apparatus has a rotor. A plurality of weights are provided in the rotor, the weights being displaced by a vibration generated in the motor due to a rotation of the rotor. The plurality of weights are rotatably provided in an annular space having a center coinciding with a rotational axis of the rotor.

摘要： An optical disc storage system (10) includes an optical disc (12) having a data surface (70) and a transducing element (30) adjacent the data surface (70). An actuator (22) coupled to the transducing element (30) positions the transducing element (30) relative to the data surface (70). The system (10) includes a spindle motor (90) and a controller (34) coupled to the transducing element (30), the actuator (22) and the spindle motor (90) for reading and writing information on the data surface (70). A hub insert (72) is coupled to the optical disc (12) and has a stiffness which is greater than a stiffness of the optical disc (12). An attachment mechanism (94, 96, 98) couples the hub insert (72) to the spindle motor (90) and stress due to the attachment mechanism (94, 96, 98) remains substantially in the hub insert (72) to thereby limit stress applied to the optical disc (12) and the resultant distortion of the optical disc (12).

摘要： A disk player includes comprises a magazine and a player portion. When a disk is played, the magazine is loaded in the player portion. A plurality of plates on which disks are to be put are stacked in the magazine. Each of the plates can be separated from each other by not sliding but moving upward and downward. In this separated state, a pickup arm which is equipped with a pickup and a chucking mechanism enters a portion between the plates. After the entrance, the plates in steps above the selected disk further rise, and the plate on which the selected disk falls. By the fall, the selected disk is put on a disk table in the chucking mechanism. Thereafter, a claw member protrudes from the disk table, to clamp the selected disk through a center hole of the selected disk. The necessity of a member for rotatably pressing the selected disk from above is eliminated. Consequently, the disk player can be made thin.
