Abstract
Mapping out restricted areas on at least one disk of a data storage device. The at least one disk includes overlapping tracks with a plurality of sectors for storing data. A first addressing is provided for the plurality of sectors on the at least one disk. Defective sectors of the plurality of sectors are detected and mapped out from the first addressing. A restricted area is calculated including sectors of the plurality of sectors and the restricted area is mapped out from a second addressing.
