Abstract
A method and apparatus for preventing off tracking from occurring in a hard disc drive that has at least one track formed using servo signals. The method includes preventing off tracking from occurring when a hard disc drive drives a hard disc having at least one track formed by servo sectors on which servo signals are recorded, checking whether the width of the track is uneven using burst regions A, B, C, and D, the burst regions A through D being included on each servo signal, and preventing the occurrence of off tracking when the width of the track is not even. Accordingly, it is possible to prevent a potential occurrence of off tracking due to a track of an uneven width, thereby guaranteeing the reliability of a hard disc. Also, a track of uneven width with other tracks in the hard disc can be changed into a track of even width, thereby increasing the processing yield during manufacturing of the hard disc.
