Abstract

The disk apparatus of the present invention comprises an actuator (3) holding a head (5) and having an engagement finger portion (45), and an inertia latch lever (11) rotatably supported near the outer peripheral portion of a disk (2) while keeping a weight balance and having a hook (43) capable of engaging the finger portion (45) of the actuator (3). The hook (43) of the inertia latch lever (11) engages the finger portion (45) of the actuator (3) at the time of non-operation. At the time of operation, the inertia latch lever (11) is rotated by airflow generated by the rotation of the disk (2) to disengage the hook (43) from the finger portion (45).
