Abstract:
A latch system for use in a disc drive, the latch comprising a latch arm for engaging a transducer support arm of the disc drive to substantially prevent movement of the transducer support arm of said drive away from a landing zone on a disc a vane coupled to said latch arm for moving said latch arm with movement of said vane, said vane being located at a distance from the center of said disc of the disc drive greater than the radius of the disc, rotation of the disc generating wind pressing against the vane to move the vane away from the disc and causing the engagement portion to disengage from the vane arm, the disc drive further comprising a pin extending from said transducer support arm, said transducer support arm and said latch moving in planes parallel to said disc so that said latch engages said pin to hold said transducer support arm in said landing zone, andwherein said pin is formed with a varying radius perpendicular to the plane of said latch and is rotatable in said support arm, so that said pin takes up any tolerances between a parking position of said wind vane and latch and said landing zone position for transducer arm.
