    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: To access data on a storage medium, at least three servo stripes simultaneously recorded in a servo track are read. The at least three servo stripes have different orientations on the servo track. An indication of a lateral position of a storage medium access head with respect to the servo track is generated based on reading the at least three servo stripes.

    摘要: The system and method for normalizing the amplitude of servo code derived signals in a disc drive, includes an improved embedded servo code format of separate magnetic dibit fields, recorded in half track steps. One magnetic dibit field is an automatic gain control field in which the magnetic head sees the same amount of magnetic dibit regardless of its position with respect to the track. A fast settling AGC loop responding to signals from the AGC field, produces a gain adjust signal while the magnetic head is still in the AGC field, which is used to normalize the amplitude of all following servo code and data code signals in that sector. The cycle of automatic gain control is repeated for each track in each sector. A sector mark following the AGC field has a magnetic dibit pattern which is fault tolerant. It is transduced in three parts to minimize error in its detection and identification and provides a timing reference for servo signals which follow. A defect dibit is recorded if the following servo gap is found to be defective during manufacture so that the next servo gap may be ignored. A track position servo code field provides signals for track following.
