Abstract
A servo sector address and a track address of a recording medium of a disk drive are encoded into a combined address value. The combined address value is stored in a combined address field that has fewer bits than the total bits required to uniquely encode the servo sector address and the track address. The position of a transducer head, indicated by the servo sector address and the track address, is determined by reading encoded values from two consecutive servo sectors on the recording medium and then decoding the encoded values.
