RECORDING MEDIUM, RECORDING DEVICE, RECORDING METHOD, AND COMPUTER PROGRAM

摘要

A recording medium (100) includes a first recording layer (L0) containing a first area and a second recording layer (L1) containing a second area. A second end of the second area is located at a position of the area portion of the second recording layer corresponding to a first end of the first area shifted toward the first end at least by a tolerance length indicating the tolerance range of a relative positional shift between an address to be defined at a predetermined position on the first recording layer and an address associated with a predetermined position on the second recording layer, or the first end of the second area is located at the position of the area portion of the second recording layer corresponding to the first end of the first area shifted at least by the tolerance length toward the second end.
