Abstract
The present invention relates to an inertial latch mechanism of an actuator of a thin disk drive device. An inertial latch mechanism comprises a latch lever rotatable on a pivot from a release position to a latch position, and an inertial lever which is rotatable on a pivot and has a moment of inertia larger than that of the latch lever. The inertial lever rotates counterclockwise when a counterclockwise shock is given to the actuator, and pulls the latch lever at a first latch part by a first latch projection to move the latch lever to the latch position. The inertial lever also rotates clockwise when a clockwise shock is given to the actuator, and pushes the latch lever at a second latch part by a second latch projection to latch the actuator which has bumped against a crash stop and is reversely rotating.
