Abstract:
A disk apparatus, comprising:a disk having a recording surface; an actuator arm with an end rotatable in a first direction from a home position located outside the recording surface of the disk so that the end is movable over the recording surface; a latch swingable between a restricted position and a release position, the latch engaging the actuator arm at the restricted position to restrict the rotation of the actuator arm in the first direction; a rotary member having a moment of inertia that is greater than that of the latch, the rotary member engaging the latch and rotating to make the latch rotate to the restricted position; a stopper for restricting the rotation of the actuator arm from the home position in a second direction opposite from the first direction; wherein at least a portion of one of the actuator arm and the stopper is elastically deformable, and when the actuator arm rotates in the second direction, the actuator arm is further rotated by elastic deformation of the portion when the actuator arm abuts the stopper; and wherein the latch has an engaging member that engages the actuator arm to make the latch rotate to the restricted position by a shock produced by the engagement, when the actuator arm is further rotated by the elastic deformation.
