Abstract

PURPOSE: To eliminate the need to seek a substitute sector by providing the substitute sector on the same track.
CONSTITUTION: Substitute sector (n) for defective sector (n-1) on a magnetic disc, etc., is provided on the same track. As a result, there is no need to seek the substitute sector provided on another track after sector (n-1) arrives and even if several defective sectors reside, lowering of write and read performance can be prevented.
