  • Servo gain compensation in a disc drive
    Patent number: 4786990
    Abstract: Compensation for servo gain variations when connected to different magnetic heads in a disc memory drive is achieved by determining individual servo gain corrections for each magnetic head at several different selected tracks on the associated memory disc, storing the individual servo gain corrections and addressing a stored individual servo gain correction for each selected magnetic head for coupling to the servo to equalize servo gain when positioning each selected magnetic head at a selected track.
