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.

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 method to at least temporarily replace air with an alternative gas in a first disk drive having a breather filter port is disclosed. A first disk drive is placed in a chamber, which is then evacuated to establish a sub-ambient chamber air pressure. Air bleeds out of the first disk drive through its breather filter port during a first period, until an internal pressure within the first disk drive reaches a reduced internal air pressure that is less than one third the first disk drive's initial internal air pressure. The chamber is then filled with the alternative gas. The alternative gas bleeds into the first disk drive through the breather filter port during a second period, until the internal pressure within the first disk drive reaches a restored internal gas pressure that is in the range 0.5 to 1.25 times the initial internal air pressure.

摘要： A disk drive includes a disk drive housing having a breather hole and a separate leak testing hole, both the breather hole and the leak testing hole being formed through the disk drive housing, and a drive sub-component attached to a surface of the disk drive housing so as to form an interface between the sub-component and the surface of the housing. The interface defines an interface outer perimeter and a sealed airflow testing channel in fluid communication only with the leak testing hole to enable a non-destructive detection of leaks at the interface. The airflow testing channel may be disposed within the interface outer perimeter.

摘要： Disclosed herein are disk drive spindle motors and disk drives using same that include one of more structures that function as travel limit stops that are designed to transfer the load created by a shock impulse to non-essential mechanical features and bypass the bearing structures, thereby keeping the load imposed thereon by the shock impulse below damaging levels. The spindle motor may also include one or more compliant members between the bearing structures and facing surfaces. Such compliant members may be combined with pre-load keepers that preload the bearings by axially compressing the compliant members.

摘要： A disk drive includes a disk drive base, a spindle motor, a first disk and a disk clamp. The rotary hub of the spindle motor includes a generally cylindrically-shaped hub wall and a hub flange including an inner annular surface adjacent to the hub wall, an outer annular surface and a flange land portion integrally formed with the hub flange. The land portion is positioned between the annular surfaces and defines a disk contact surface projecting above the annular surfaces, the disk contact surface being substantially centered on the hub flange. The first disk is supported by the disk contact surface to form a clearance between the annular surfaces and the first disk. A second disk may be coupled to the spindle motor and an annular disk spacer may be positioned between the disks. The annular disk spacer includes a first spacer surface facing the first disk and a second spacer surface facing the second disk. The first and second spacer surfaces each comprise an inner annular spacer surface adjacent to the hub wall, an outer annular spacer and a spacer land portion integrally formed with the spacer and positioned between the annular spacer surfaces to define a spacer-to-disk contact surface that projects from the annular spacer surfaces to form a clearance between a respective disk and respective annular surfaces. The disk clamp for applies a clamping force to the first and second disks that is substantially centered on each spacer-to-disk contact surface and on the disk contact surface.
