    摘要： A slider having leading and trailing edges is configured to fly on an airbearing above a data storage disk rotating from the leading edge to the trailing edge. Read and write heads are mounted on the slider proximate the trailing edge. An auxiliary thermal sensor is mounted on the slider, but preferably nearer the leading edge. Forward placement of the sensor allows it to sense mechanical defects before they reach the heads, thereby permitting a write inhibit operation, for example. The sensor may also be used to detect airbearing modulation. Appropriate action may be taken when unacceptable airbearing modulation is detected, such as notifying the user and/or scrubbing the slider. The sensor is preferably wider than the heads. This allows, for example, an in-situ glide test to be performed faster using the sensor. An arm electronics module is preferably configured to permit concurrent operation of the sensor and heads.

    摘要： An apparatus and method of controlling an actuator of a data storage device detect and/or correct narrowband mechanical excitations such as due to spindle bearing defects through sensing and/or rejecting disturbance frequencies associated with such narrowband mechanical excitations in an actuator control signal generated by a data storage device controller. A narrowband filter may be used to reject, from an actuator control signal generated by a data storage device controller, a disturbance frequency associated with a spindle bearing defect in a data storage device, and disposed in proximity to a zero crossover frequency associated with the data storage device controller. In addition, a peak filter disposed in a control loop of a data storage device controller may be configured to detect a spindle bearing defect in a data storage device by detecting an amplitude of a control signal in the control loop in proximity to a disturbance frequency associated with the spindle bearing defect.

    摘要： A deformable shock absorbing device for a computer apparatus or a precision apparatus is provided. An embodiment of the shock absorbing portion includes an outer disk, an inner substrate with a valve, and an elastic member therebetween, creating a cavity whose inflow or outflow is allowed by the valve. When the computer apparatus is moved away from a resting surface, the elastic membrane facilitates the inflation of the shock absorbing device with air or fluid and the device projects outwardly from the bottom surface of the computer. If the computer comes into sudden contact with the surface, the force of impact is absorbed by the shock absorbing device which deflates gradually. Thus, internal structures of the computer apparatus can be prevented from being damaged.

    摘要： In a first aspect, a disk drive includes a base and a disk assembly, including at least one data storage disk, rotatably mounted on the base. The disk drive further includes structure for defining an electrostatic discharge gap between the base and the disk assembly. For example, one or more point electrodes may be provided on the disk assembly, to define the electrostatic discharge gap relative to one or more stationary electrodes mounted on the base. Damaging electrostatic discharges through the read/write head, or at a surface of the data storage disk, may be prevented by the present invention.

    摘要： An apparatus and method reduce the transfer of vibration to and/or from a data a data transfer mechanism in a data storage device by coupling an adaptive mount responsive to an electrical stimulus to the data transfer mechanism. In one embodiment of the invention, a controller reads a signal that relates to the position error of a read/write component in a data transfer mechanism, applies an algorithm, and varies the damping of an adaptive mount coupled to the data transfer mechanism. The controller may be further configured to report an error to a host system that identifies a substandard data transfer mechanism so that such data transfer mechanism can be repaired or replaced.
