ABSTRACT:
In response to a supply of sync and re-sync mark detection failure status signals for data to be written or read, a re-sync mark detection window expanding device advances a timing of opening a re-sync mark detection window to be earlier than an instant of generation of the sync or re-sync detection success status signal, thereby improving the possibility of detection of the next re-sync mark.
