Abstract:
An inertial latch mechanism for latching an actuator in a disk drive device at a rest position when a shock is given to said disk drive device comprising:a latch lever rotatable on a first pivot between an actuator release position where the latch lever is not in contact with the actuator and an actuator latch position where the latch lever is in contact with the actuator; andan inertial lever rotatable on a second pivot, and having a moment of inertia about the second pivot which is larger than a moment of inertia of the latch lever about the first pivot, the inertial lever rotatable in a first direction from the actuator release position to contact the latch lever and move the latch lever to the actuator latch position and the inertial lever rotatable in a second direction from the actuator release position to contact the latch lever and move the latch lever to the actuator latch position.
