摘要： A data storage system has a disk having a first, second and third zone. The first zone has rough texturing to prevent stiction between a slider at rest and the disk. The second zone has intermediate texturing to prevent stiction when a moving slider is in contact with the disk. The third zone has a smooth texture and is used for data recording. A control unit moves the slider between the zones as appropriate on power up and power down of the system. The system has an actuator latch having a bias device. The bias device allows the slider to be positioned between the first and second zones by selective energizing of the actuator while in the latched position.

摘要： A hard disk drive utilizes a spacer ring at its inner diameter to load and unload the read/write heads. During relatively small shock events, the actuator is retained relative to the disk through a circumferential groove in the spacer ring. A complementary protrusion on the load/unload tab extends from the actuator into the groove to complete the retention. A tribological coating on the spacer ring and/or protrusion significantly reduces wear therebetween. However, during large shock events an inertial latch is used by the system to hold the actuator in place.

摘要： A disk drive suspension has a longitudinal axis that defines inner and outer edges of the suspension. A flexure having a head gimbal assembly is aligned with the axis and spring-loaded to the suspension. A single limiter extends from the flexure through an opening in the suspension to hook to the suspension. The limiter limits the planar separation between the flexure and the suspension. The limiter is offset from the axis such that it is located much closer to the inner edge. During the unloading of the suspension from the disk, a tab on the suspension engages a ramp to begin to lift the suspension away from the disk. As the suspension is lifted, the flexure and head gimbal assembly have limited planar separation from the suspension due to the limiter. Since the limiter is offset from the axis, the surface of the head gimbal assembly is skewed relative to the disk. The offset limiter reduces the chance of the hub-side edge of the slider contacting the disk surface, since the limiter lifts the slider from hub side. For the same reason, the rim-side edge of the slider comes off the disk last, thus increasing the chance of contacting the disk at that point.

摘要： A hard disk drive contains magnetic disks which are accessed by a series of pivotable arms. Each arm has a pair of flexible, cantilevered suspensions and a head gimbal assembly with a magnetic read/write head secured to each suspension. A tab extends from and forms part of the end of each head gimbal assembly. The hard disk drive also has a stationary cam member located near the outer edges of the disks. The cam member has a series of rigid cantilevered fingers with contoured surfaces. Each surface has three spaced-apart detents with a recess located between each adjacent pair of detents. The second recess on each surface has a lubricant-filled reservoir. For the majority of its operation, the drive pivots the arms between an operational range adjacent to the disks, and a park position in the first recess when the drive is not in use. The tabs slide along the support surfaces of the fingers when the arms move to the retracted position. At selected intervals, the support surfaces of the fingers may be lubricated by briefly moving the arms to a lube position with the tabs in the second recess. The small amount of lubricant applied to the tabs is sufficient to relubricate the support surfaces of the fingers as the tabs slide on the fingers for a number of cycles.

摘要： A method for measuring the clearance of a slider over a rotating disk by inducing a collision between the slider and the disk is described. After the normal flying height of the slider is established, the slider is driven into a collision with the rotating disk surface by applying a DC or AC voltage between the slider and the disk. The clearance data can be extracted from the induced collision by measuring a parameter, such as the change in the amplitude of the readback signal from the magnetic sensor, which is related to fly-height at the normal fly-height and at the disk surface. The two data points can then be used to derive the clearance. One embodiment uses a single beam interferometer to derive the vibrational displacement of the collision event.

摘要： An active damping control for a disk drive includes an i.d. crash stop and an o.d. crash stop which constrain the motion of an actuator arm. Each crash stop includes an inner core manufactured from a material that generates current when mechanically strained. The inner core of each crash stop is connected to a circuit that includes an energy dissipating element that dissipates energy received from either crash stop. Thus, when the actuator arm collides with either crash stop, the rebound of the actuator arm off the crash stop is minimized.
