Abstract
Test data is written in tracks of a discrete track medium by making the tracks eccentric by accessing a plurality of tracks by forcibly making a composite magnetic head eccentric under an ON track servo control. The test data written in the tracks which are pseudo-eccentric are written in the tracks with the original write sensitive width of a write head. It is possible to obtain a read characteristics profile having a peak by tracing and reading the test data while moving the composite magnetic head (read head) which is forcibly made eccentric in a radial direction.
