Abstract
A disk drive including a disk storing a defect log including one or more defect records, wherein each of the defect records comprises record fields, and a controller configured to determine a match for a reference defect record by at least selecting one or more record fields of the reference defect record as search fields, setting the search fields in the reference defect record, generating a mask record comprising mask fields corresponding to the record fields, setting a first bit value for each bit in the mask fields corresponding to the search fields and a second bit value for each bit in the mask fields which do not correspond to the search fields, selecting a defect record from the defect log, generating an intermediate result by performing a first logic operation, and generating a matching result by performing a second logic operation.
