Abstract
According to an embodiment, a disk device includes a latch mechanism configured to retract a head on a distal end portion of an actuator to a ramp mechanism and latch a ferromagnetic member disposed on the actuator on the side of a motor coil by a latch magnet, a shaft protruding from that part of a base of the disk device which is located near the latch mechanism, and a rotary lever pivotably mounted on the shaft. The rotary lever includes a first arm on the disk side being extended over the disk so that the rotary lever is rotated by a pressure of airflow produced as the disk rotates, and a second arm on the latch magnet side configured to move as the rotary lever is rotated by the airflow pressure, to weaken magnetic coupling between the latch magnet and the ferromagnetic member.

A disk device comprising:
- a latch configured to retract a head on a distal end portion of an actuator to a ramp near the outer periphery of a disk and to latch a ferromagnet on the actuator on the side of a motor coil by a latch magnet;
- a shaft protruding from a base of the disk device near the latch;
- a rotary lever configured to pivot on the shaft, the rotary lever comprising a first arm on the disk side extending over the disk in such a manner that the rotary lever is rotated by a pressure of airflow due to rotation of the disk;
- and
- a second arm on the latch magnet side configured to move as the rotary lever is rotated by the airflow pressure, and to weaken magnetic coupling between the latch magnet and the ferromagnet.
