Abstract
In a disk apparatus, a movable-base position sensing switch ( ) is provided such that the sensing switch is turned from ON state into OFF state at a time a turntable ( ) of a movable base ( ) is separated from a clamper ( ) during movement of the movable base ( ) to an unclamped position. A motor ( ) is controlled ( , S -S ) so that a driving force of the motor is used to move a tray and/or to move the movable base through a drive device. The motor is actuated in a first direction to move the movable base to the unclamped position for a first period from the time the position sensing switch is turned into OFF state. The motor is actuated in a reverse direction for a second period from an end of the first period. The driving of the motor is stopped for a third period from an end of the second period. The motor is actuated in the first direction from an end of the third period such that the tray is moved to the disk-change position.
