摘要： A method of, apparatus for, and means for controlling pitch of a servowritten track on a disc in a disc drive are disclosed. The disc drive has a head for traversing over a surface of the disc. The head has a read element and a write element separated by a head element offset &Dgr;. A servowriting controller operably connected to the disc drive creates a track k by writing servo information on the disc. The servowriting controller then calculates the head element offset &Dgr; at the track k, [&Dgr;CALC(k)] and determines a skew angle &thgr; at the track k, [&thgr;(k)]. The servowriting controller adjusts a track pitch correction factor based on the &Dgr;CALC(K) and the &thgr;(k) such that the track pitch correction factor is utilized to servowrite a next track.

摘要： Many parallel tracks on a storage surface of a data handling device are arranged in a longitudinal direction. Each track has a track center comprising reference points for fine lateral positioning. Each successive pair of track centers has a succession of lateral offset distance having an average. Because there are many successive pairs of tracks, there are many average lateral offset distances defining a statistical distribution having a variance. The device includes a laterally movable transducer head and a longitudinally movable data surface. A signal is received from the transducer head while the data surface moves past the head. Many values each indicative of a lateral offset distance between a corresponding pair of lateral reference points are derived from the received signal. These offset-indicative values are used to shift at least some of the latitudinal reference points laterally so as to reduce this variance.

摘要： A method of calibrating magnetoresistive (MR) head geometry for a product head in a selfservo writing disc drive includes the steps of writing a first burst at an inner diameter of a disc surface using the write head of the product head. Next, the first burst is read using the MR read head of the product head, and a first read amplitude of the first burst is determined. From the first read amplitude of the first burst, it is determined which one of a multiple different sets of subsequent inner diameter steps to perform. Then, the one of the multiple different sets of subsequent inner diameter steps is performed to determine a read head width, a write head width, and a read-write offset between the read head and the write head.
