Abstract
A servo system for controlling the position of a read/write head over a rotating data disk is disclosed. The servo system includes the addition of a compensation scheme to the feedback loop that causes the open loop gain of the servo to increase only in a very narrow spectrum of its operating bandwidth. In a preferred embodiment, the compensation takes the form of a second order digital filter combined with a proportional-integral-differential phase compensation filter in the feedback loop of an embedded servo system for a digital data disk drive.
