Abstract:
A tracking method for a high speed search operation of a recording medium having a plurality of recording tracks each having first and second recording regions in which the first recording region has recorded therein a DC coefficient and a predetermined number of low-frequency AC coefficients from among a plurality of AC coefficients and the second recording region has stored therein the DC coefficient and the plurality of AC coefficients, the tracking method comprising:scanning only the coefficients recorded in the first region of a predetermined one of the recording tracks selected from among N continuous recording tracks, wherein all the coefficients recorded in the first region of the predetermined recording track are scanned; andscanning only some of the coefficients recorded in the second region of the N continuous recording tracks, wherein the only first region scanned from among the N continuous recording tracks is the first region of the predetermined recording track.
