In a latch release apparatus and method, a latch mechanism holds an actuator with a high shock resistance. Two or more magnetic members are arranged in a latch component so as to concentrate a magnetic force for easy rotation of the latch component. The effect of the magnetic force in a direction perpendicular to the direction of rotation of the magnetic members becomes smaller, reducing the friction force at the rotational center of the latch.

Method and apparatus for information recording and reproducing using an air force latch mechanism

In a latch mechanism that holds an actuator with a high shock resistance two or more magnetic members are arranged in a latch component, which generates a weaker attraction force but a more easy rotation of the latch component. The structure concentrates a magnetic force in order to rotate the latch component effectively. The effect of the magnetic force in a direction perpendicular to the direction of rotation of the magnetic members becomes smaller and a friction force at the rotation center of the latch is reduced.
