Abstract
A method for adjusting the frequency response of a servo loop is provided that positions a servo head at a nominal position over a medium and determines the frequency response of the servo loop. A compensation gain is determined at the nominal position such that when the compensation gain is combined with the servo loop's frequency response, the compensation gain causes the frequency response to approach a desired frequency response. In addition, a servo loop and a disc drive with such compensation gain are provided.
