The present invention relates to a data recovery technique for recovering unrecoverable data from a sector having a synchronization field damaged after formatting time or a synchronization mark that has been written improperly. The present invention may try conventional or traditional data recovery techniques first, but if these techniques are ineffective, these techniques can be bypassed in favor of an additional recovery mode. Based upon overall design parameters of a disk drive system and the recording medium format, the disk drive firmware estimates a synchronization mark starting position, analyzes the accuracy of that position and when re-synchronization has not yet occurred, the firmware makes iterative estimates within a window relative to the starting position, and analyzes these subsequent positions for accuracy as well. Once a synchronization mark is located, the data in the sector can be recovered.
A method for the recovery of data from a recording medium wherein a synchronization field is at least partially unreadable, said method comprising:
A method for the recovery of data from an unreadable sector having at least a portion of a synchronization field that is unreadable, said method comprising:
A method for the recovery of data from a recording medium, comprising:
