Abstract
A method for optimizing a write offset margin includes the steps of writing test data on a recording medium along a track defined thereon by a head, reading the test data from the recording medium by the head while changing an offset of the head with respect to the track, determining a maximum offset that provides agreement between the test data written into the recording medium along the track by the head and the test data read out from the recording medium by the head along the track, and setting a write offset margin for the magnetic disk based upon the maximum offset.
