摘要： A disc drive is provided which incorporates a rotatable actuator which is mounted to a base of the disc drive through a pivot mechanism. The actuator positioning is controlled by a servo system and during track following operations, the actuator arm is caused to move. In one embodiment, the servo tracks incorporated in the disc drive are distorted when written in by the injection of a sinusoidal signal. In another form, the disc containing the servo information is caused to rotate about an axis which is offset from the disc axis. A method of creating a servo track is also disclosed.

摘要： Apparatus and method for mounting a disc drive with vertical and horizontal compressible elements and for stabilizing the disc drive during use. Shock mounts are affixed to a horizontal surface (i.e. parallel to a data surface) of the disc drive, slowing vertical shock pulses transmitted from the frame to the disc drive. Recessed vertical surfaces are formed on sides of the housing to accommodate additional dampeners, which slow horizontal shock pulses while reducing operating vibration.

摘要： An apparatus for unloading a moveable member comprises a ramp structure with an inclined surface. A lift tab of the moveable member advances along the ramp structure to the inclined surface while pivoting about a pivot point to undergo an increase in elevation above a base surface. The inclined surface has a slope determined in relation to angular deflection of the lift tab induced by said increase in elevation. Preferably, the slope of the inclined surface substantially matches an angle of the lift tab when the lift tab is disposed on the inclined surface. The inclined surface preferably constitutes a parking surface, and the ramp structure further preferably comprises an entry/exit ramp surface and a latch surface along which the lift tab travels to reach the parking surface. The moveable member preferably comprises a flexible suspension which supports a transducer adjacent a data storage medium in a data storage device.

摘要： An actuator control system for a two-stage actuator system of a disc drive has a first, or primary, stage actuator consisting of a voice coil motor that positions the head relative to a disc and a microactuator that alters the actuator system without operation of the voice coil motor. A control loop includes a controller responsive to seek commands to operate the voice coil motor, thereby moving the head relative to the disc. An active damping circuit is coupled to the head to operate the microactuator to damp resonance modes of the actuator system.

摘要： The shock absorber apparatus for a disc drive is a molded polymeric enclosure adapted to receive and retain a disc drive. One preferred embodiment of the present invention has a shock absorbing material of a first thickness adjacent a critical region of the drive and a second thickness of shock absorbing material adjacent a non-critical region of the disc drive. The first thickness is greater than the second thickness in order to absorb a greater shock load to protect the critical region of the disc drive.

摘要： A disc drive includes a transducer having a separate element for writing information and a separate element for reading information to and from the disc. In a disc drive designated to read and write long sequential records, the track misregistration budget is reduced to account for previously written tracks not being encroached on one side. An initial track is written. Subsequent tracks are written after a seek in one direction. The subsequent track is written so that the initially written track is overwritten to one side and leaves a track having a width substantially equal to the width of the read element. Records can be written into data bands of a selected number of tracks. A guard band is left between groups of data bands so that data on tracks in subsequent data bands are not overwritten.
