  • Method for following data tracks in a disc drive using an improved thermal calibration method
    Patent number: 5424885
    Abstract: A method for following data tracks on data surfaces of a disc drive by organizing the data tracks in concentric cylinders including servo tracks on a dedicated servo surface and following servo tracks with a servo transducer that is offset from the servo track to align selected data transducers with the data tracks. To measure the offset for each data surface, a calibration correction track is written to one data surface while a track on the servo surface is followed and the correction track is read by a thermal calibration circuit while following the servo track with an offset to obtain a calibration correction indicative of electronic offsets in the thermal calibration circuit.
