Estimating the term…
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 Δ. 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 Δ at the track k, [ΔCALC(k)] and determines a skew angle θ at the track k, [θ(k)]. The servowriting controller adjusts a track pitch correction factor based on the ΔCALC(K) and the θ(k) such that the track pitch correction factor is utilized to servowrite a next track.
A method of controlling a track pitch on a disc in a disc drive, wherein the disc drive has a head for traversing over a surface of the disc, the method comprising steps of:
An apparatus for controlling pitch of a track on a disc in a disc drive, wherein the disc drive has a head, for traversing over a surface of the disc, that has a read element and a write element separated by a head element offset Δ, the apparatus comprising:
