摘要： A disk drive is disclosed comprising an enclosure, a disk, a head actuated radially over the disk, a spindle motor for rotating the disk, and a ratchet arm having a base end connected to the enclosure of the disk drive and a wind vane extending from the base end adjacent the disk. The ratchet arm engages the disk when the disk is not rotating, and the ratchet arm disengages from the disk due to windage pushing on the wind vane, the windage generated by the disk rotating at an angular velocity greater than a threshold.

摘要： A transducer suspension for a drive system has a beam which is bendable in a vertical direction for holding the transducer adjacent to the media, but is torsionally stiff for quicker access times and reduced noise and errors. This inherently contradictory performance occurs by joining a laterally elongated brace which is torsionally stiff about its elongated dimension across a pair of laterally disposed strips to cause the strips to flex in unison, allowing bending but reducing torsional motion in the suspension about an axis which is substantially perpendicular to the torsionally stiff axis of the brace. The torsionally stiff brace may take the form of a tube having a rectangular, triangular or circular cross-section, and may be formed of material cut from the suspension to define the hinge strips. The brace may have reduced longitudinal dimensions at the connections to the strips to further filter torsional versus bending vibrations. A plurality of braces joined to hinge portions may also occur in a single suspension for increased effect.

摘要： A disk drive is disclosed comprising a disk, a head actuated radially over the disk, and a spindle motor for rotating the disk. The spindle motor comprises a stator having at least one stator coil wrapped around a stator tooth. The spindle motor further comprises a hub rotated by the stator when current is applied to the stator coil, and a locking spring arm having a fixed base. The locking spring arm engages the hub when no current is applied to the stator coil, and the locking spring arm disengages from the hub when current applied to the stator coil generates a magnetic flux which pulls the locking spring arm away from the hub.
