摘要： There is provided a disk drive including first and second sliding members (69, 71) made to slide in synchronization with each other, a sliding-member movement driving mechanism (70) to move the first sliding member (69) and have the second sliding member (71) slide in synchronization with the sliding of the first sliding member (69), and a shock absorbing mechanism (83) interposed between the first and second sliding members (69, 71). The shock absorbing mechanism (83) includes a shock absorbing member (84) to absorb a difference in movement between the first and second sliding members (69, 71), caused by an external force to the optical disk brought into or to outside a housing (3) through a disk slot (21) in a direction opposite to the direction in which the optical disk (2) is loaded or ejected when the first sliding member (69) is moved by the sliding-member movement driving mechanism (70)

摘要： There is provided a disk drive in which a base lifting mechanism (93) makes a first disk chucking operation to place an optical disk (2) on a disk mount (27) by elevating at least a base (31) to a disk chucking position, lowers the base (31) to an intermediate position between the disk chucking position and a disk releasing position so that a disk rotation driving mechanism (28) spins the optical disk (2) which will thus take another phase, elevates the base (31) to the disk chucking position again, and makes a second disk chucking operation to place the optical disk (2) on the disk mount (27). Thus, the optical disk can positively be chucked onto the disk mount.
