Description

  The present invention relates to a disk device in which a disk is held on the side of an upper lid having a clamper and the disk is rotated by rotating the upper lid.

  In the conventional disk device, the disk is held and rotated by a turntable and a clamper. However, the turntable and the clamper have a problem that the disc may run out only by holding the central portion of the disc. In addition, even when the disk is eccentric, there is a problem that surface deflection occurs in the disk.

  The first prior art is shown in FIG. This conventional turntable includes a shaft (not shown) 104 provided on the outer periphery of a turntable 102 on which an information recording medium 103 is placed and driven to rotate, and a weight 107 under the turntable. A clamp claw 106 having a claw portion 106 a that presses the outer peripheral portion of the information recording medium 103 is rotatably attached to the claw portion due to centrifugal force acting on the weight 107 accompanying the rotation of the turntable 102. The configuration is such that 106 a rotates in the clamping direction and presses the outer peripheral portion of the information recording medium 103. (For example, refer to Patent Document 1).

However, this is because the information recording medium 103 is rotated by the lower turntable 102 and not from the upper side.
