ABSTRACT:
A read/write head for use with bit-patterned media detects write synchronization errors between a write clock and the bit-patterned media. In particular, the read/write head writes data to the bit-patterned media using a write clock. The data is then read from the bit-patterned media and used to detect write synchronization errors between the write clock and the location of bit-islands on the bit-patterned media. Based on detected write synchronization errors, the phase associated with the write clock is modified to align the write clock with the location of bit-islands on the bit-patterned media.
