Abstract
Method and apparatus for improving the operational response of a disc drive. Compensation routines are performed to adjust disc drive parameters in accordance with existing environmental conditions during an idle mode of operation of the drive. At such time that a selected, uninterrupted amount of time passes since the most recently performed disc drive operation, the disc drive enters the idle mode and performs a predetermined sequence of the compensation routines, after which the disc drive performs dithering in which heads of the disc drive are positioned about various locations with respect to the corresponding discs of the disc drive. A compensation table is provided setting forth the predetermined sequence of the compensation routines and the table is reordered so that the compensation routines are subsequently performed in a different sequence.
