PURPOSE:To give no damage to a recording surface of a disk by a supporting means even when an oscillation is applied to a moving disk, by providing an inclined surface for guiding the moving disk between a case engaging means and a turntable. CONSTITUTION:An engaging member 62 is rotatably supported by a fixed base 80 through a shaft 74 and a bearing 63, and engages with an engaging hole 13 of a case 2. When a disk holding mechanism is moved in a direction of X2, a roller 103 provided to a sliding member 102 of the disk holding mechanism 90 abuts on an inclined surface of an abutting member 43 and the sliding member 102 operates in a direction of Y1 and the disk holding mechanism 90 does not hold the disk. Under this condition, the disk is held by an mounting ring 133 at a center section. 4Thereafter, when by an operation of a cam unit 160, the mounting ring 133 is lowered, the disk is mounted on a turntable 130. |
