Abstract
A disk apparatus includes a disk holder for holding a disk, and the disk holder is reciprocatively movable between a loading position and an unloading position. The disk apparatus further includes a motor for driving the disk at the loading position for reading or writing purposes, a power transmission mechanism for converting the rotation of the shaft of the motor into a reciprocative motion and for transmitting the reciprocative motion to the disk holder, and a switching mechanism for switching the power transmission mechanism to an inoperative state so as to prevent the power of the motor from being transmitted from the motor to the disk holder when the motor is operating to rotate the disk for reading or writing purposes.
