RECORDING DEVICE, RECORDING METHOD, AND COMPUTER PROGRAM

摘要

A recording apparatus (200) is provided with: a recording device (352) for recording record information onto a recording medium (100), provided with: (i) a first recording layer (L0) which is irradiated with the laser light (LB) to thereby record therein the record information and which has a first area (109) in which the record information is recorded; and (ii) a second recording layer (L1) which is irradiated with the laser light through the first recording layer to thereby record therein the record information and which has a second area (114) whose edge on an inner circumferential side corresponds to an edge on an outer circumferential side of the first area; and controlling device (354) for controlling the recording device to pre-record pre-information, into an area portion of the first area, other than an area portion having a size corresponding to a tolerance length, which indicates an acceptable range of a relative position shift between an address which is defined on the predetermined position in the first recording layer and an address which is related to the predetermined position in the second recording layer, with the edge on the outer circumferential side of the first area as a starting point.
