Abstract
An inertial latch for preventing an actuator arm, which is a component of a disk apparatus, from flying out from an unloading position because of an external shock. The actuator arm cannot be prevented from flying out from the unloading position because of repulsion produced when the actuator arm crashes against a stopper, by operation other than an external shock. A latch, for engaging with a point end portion of the actuator arm to prevent the actuator arm from flying out, is provided with a sensing protrusion 16e. When the actuator arm crashes against an outer crash stop, the shock causes the latch to rotate and engage with the actuator arm, whereby the actuator arm is prevented from flying out.
