摘要： A system and method for overcoming adhesion between media and a surface of a storage device in contact with the media. A storage device comprises a media velocity detector and a media drive motor controller. The media velocity detector detects storage media velocity as torque is applied to a storage media. The media drive motor controller causes a media drive motor to apply acceleration torque to the storage media. If the media velocity detector detects no increase in media velocity as acceleration torque is applied to the storage media, then the media drive motor controller causes the media drive motor to apply a torque pulse to the storage media.

摘要： An improved method and apparatus for performing seek and track follow operations in a disc drive provides time varying acceleration profile and track position trajectory signals which have the same time duration and which are developed as a function of seek length. These signals are successively simultaneously sampled at the same points in time. The sampled acceleration profile and track position trajectory signals from the same points in time are simultaneously applied as a feed forward signal and a position reference signal, respectively, in the disc drive to position a magnetic head at a selected track. During a seek operation, each actual track position signal and subtrack position signal from the transducer is compared with an existing sampled track position trajectory signal. At the end of the seek movement, track following continues under the control of the subtrack position signals.

摘要： Improvements are realized in magnetic disc drives in minimizing servo gain variations from one head to another and in differing track offset positions by providing servo code patterns and methods of fabricating such patterns in which magnetic heads of differing widths overlap the same amount of servo code and in which servo gain variations in track offset positions are minimized by maintaining servo code overlap by the magnetic heads relatively constant up to substantially one-half track offsets of magnetic head.

摘要： Compensation for servo gain variations when connected to different magnetic heads in a disc memory drive is achieved by determining individual servo gain corrections for each magnetic head at several different selected tracks on the associated memory disc, storing the individual servo gain corrections and addressing a stored individual servo gain correction for each selected magnetic head for coupling to the servo to equalize servo gain when positioning each selected magnetic head at a selected track.
