    Abstract: A method and apparatus for compensating for head-to-disk contact-induced disturbances in a hard disk drive is disclosed. The method includes determining topographical variations across a surface of a disk during the manufacturing or operation of the hard disk drive. Error signal variations that occur as a result of head-to-disk contact-induced disturbances resulting from the topographical variations are recorded. Current to a voice coil motor in the hard disk drive is varied to correct for the contact-induced disturbances before they occur.

    Abstract: A dual-stage actuator disk drive has calibration tracks located in a nondata band, and uses a secondary-actuator failure detection and calibration test run by the servo control processor. The calibration tracks contain a pattern of pre-written magnetized test blocks. The test is run with the primary actuator biased against a crash stop, which enables the read head to access the calibration tracks. The servo control processor generates a test signal to the secondary actuator and receives a calibration signal from the read head as the read head detects the test blocks in the calibration tracks. The test comprises two measurements: a measurement of the secondary actuator static characteristics, and a measurement of the secondary actuator dynamic characteristics.

    Abstract: A data recording disk drive has a plurality of capacitive sensors, each sensor facing a surface of an associated disk, a capacitance sensing circuit for converting the sensed capacitance to a voltage representative of the distance between the sensor and the disk surface, and a feedforward controller that receives the voltage signal. The feedforward controller has a transfer function with gain and phase characteristics designed to match the transfer function from the out-of-plane disk vibration to the position of the read/write head while accounting for the effects of the sensor dynamics and the dynamics of the actuator. The output from the feedforward controller is combined with the output from the disk drive's servo feedback controller so that the effects of disk vibration on track misregistration of the head are removed from the control signal to the actuator.

    Abstract: A communication method for retrieving stored data from an MWD tool, through an antenna used for conventional EM data telemetry. The method comprises establishing electrical contact between a surface transceiver and an EM data telemetry antenna upon retrieval to the surface. The MWD tool then transfers data through the antenna, the data being received by the surface transceiver. Also provided is an electrical isolation connector subassembly comprising an electrically insulative coating to electrically isolate the splitsub components, thereby forming the antenna for data transfer and EM data telemetry.
