Abstract
An optical recording device for recording to a disk having a guide layer and a plurality of recording layers includes a controller which obtains, by calculation, logical addresses of data areas of all recording layers on the basis of physical addresses of a guide layer and recording layer information. Specifically, in treating the maximum value (last physical address) of physical addresses in the guide layer as PSN_max, recording layer information of recording layer Lx as x (x=0, 1, 2, . . . ), physical addresses corresponding to recording destination positions in the data area of recording layer Lx as PSN, and logical addresses imparted to data units recorded at recording destination positions in the data area of recording layer Lx as LSN, calculation for LSN=(PSN_max*x)+PSN . . . (1) is performed.
