Method of determining and applying adaptive track zero position and disc drive using the same
A method of determining, and an apparatus to determine, a track zero position of a disc in a disc drive, the method including seeking, sequentially, in units of predetermined numbers of tracks, outwardly from a designed track zero position to a predetermined critical track position of the disc; determining whether track following is performed normally during the seeking; and determining an actual track zero position by shifting the designed track zero position inward by a predetermined number of tracks in response to the track following not performing normally, and determining the actual track zero position to be the designed track position in response to the track following performing normally.
