Abstract
Formatting is applied only to a local area which is a part of the entire recordable area of a rewritable disk and which does not include portions where a lead-in area and a lead-out area are to be formed. In other words, only the required minimum area is formatted. The formatted area is extended afterwards as required. Thus, disk formatting is shortened.
