Patent ID: 7203034

Claim:
A rotary disk storage device comprising: a housing; a rotary disk recording medium having a recording area, at least a partial area of the recording medium being formed of an electrically conductive material; an actuator suspension assembly to which a head/slider is attached and which includes a voice coil motor, said actuator suspension assembly being adapted to operate in such a manner that said head/slider moves between a retracted position and said recording area centrally about a pivot shaft supported by said housing; an eddy-current magnet disposed in proximity to a surface of the area of said rotary disk recording medium which area is formed of the electrically conductive material, said eddy-current magnet having a magnetic pole opposed to a surface of said rotary disk recording medium; a movable structure which releases said actuator suspension assembly restrained in said retracted position, said release being carried out by utilizing a force of an eddy current exerted on said eddy-current magnet which eddy current is produced in said rotary disk recording medium by said magnetic pole; and a biasing structure which, when said rotary disk recording medium is rotating at a predetermined number of revolutions or less or is at a standstill, imparts a biasing force to said latch member to turn the latch member to said restraint range, wherein said biasing structure includes a stator magnet of said voice coil motor.
