Abstract
Write on the fly certification of magnetic media includes detecting the start of a defect. A sequence of defect matrices is written over the defect with a write element in a read-after-write head. Each defect matrix in the sequence is read with a read element in the read-after-write head. A check is made to determine if an error exists in the data read from each defect matrix. The defect is determined to extend through each defect matrix if an error exists in the read data.
