Abstract
A method is provided for correcting a write defect in a data storage apparatus comprising a storage medium. The method comprises reading information from a track of the storage medium in which a write defect occurs, calculating a number of error-corrected error correction code symbols in sectors of the track based on the read information, determining a number of sectors on which write defect correction is to be performed by comparing the calculated number of error-corrected error correction code symbols with a threshold, and performing a rewrite operation on the track, beginning at a starting sector determined by the number of sectors on which write defect correction is to be performed.
