ABSTRACT:
A method of reproducing data by performing error correction on data read from a recording medium. The method includes reading a sync pattern, checking if the sync pattern has been read, recovering data following the sync pattern when the sync pattern has not been read, and performing the error correction on the recovered data. The data following the sync pattern is recovered in the error correction, which makes it easier to lengthen the time width of a detection window setting signal for detecting the sync pattern.
