摘要

An apparatus for detecting a probe position error includes a position error extracting unit extracting probe position errors from signals detected by a probe; a position error adding unit calculating the probe position errors in units of a predetermined time; and a signal processing unit storing a past probe position error calculated by the position error extracting unit and generating a probe position error by processing the past probe position error and a current probe position error. An apparatus for tracking data includes a scanner moving a data storage medium; a probe detecting the signals from a data storage medium; an error detector detecting probe position errors in a half-period of an error extracting signal by applying the error extracting signal used to extract the probe position errors to the signal detected by the probe; and a compensator compensating for the probe position errors detected by the error detector.
