A method for generating an index pulse with an index pattern in a hard disk drive, is disclosed including the steps of: (a) reading out and searching for a plurality of index patterns from a magnetic disk which previously stores patterns of sequential correlations in an index pattern domain of a servo domain of one sector; (b) detecting whether the plurality of index patterns read and searched in the step (a) are sequential; (c) detecting whether the index pattern is for the first sector, using the sequential correlation of the sectors, if the index patterns are sequential in the step (b); and (d) transmitting an index pulse generating signal to a gate array to thereby generate an index pulse, if the first sector is detected in the step (c).
