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.
An optical recording device for recording to a disk that has at least one guide layer with a guide track where physical address information is recorded, and multiple recording layers where data is recorded according to the guide track, said optical recording device having a physical address playback part that obtains the physical address information from the guide track in the guide layer, as well as a control part that uses the obtained physical address information and information identifying each of the recording layers to calculate a logical address to be assigned to each data recorded to the recording layer.
A method of recording to a disk having at least one guide layer with a guide track where physical address information is recorded, and multiple recording layers where data is recorded according to the guide track, said optical recording method comprising:
