Abstract
In a storage medium such as a DVD+R or DVD+RW disc having a plurality of recording layers, the maximum address (i.e., the maximum physical sector number of a layer) of a user-data-recordable region (data zone) in each recording layer is recorded as physical format information in a wobbling groove. Based on the information, a recording/reproducing apparatus checks the maximum address of a data zone in each recording layer.
