摘要

Provided is a recording device (101) for recording record data onto a recording medium (11) that includes a guide layer (12) and a plurality of recording layers (13) and has a management area (130) in which user domain information for specifying a user domain (UD) and buffer area information for specifying a buffer area (BA) are recorded as track management information (131). The recording device (101) includes: a generation means (111) that generates management information; and a recording means (102, 103, 111) that projects a recording/reproducing laser beam (LB2) to the recording layers while carrying out tracking control using a return beam of a guide laser beam (LB1) on the basis of the management information so as to record the record data onto the recording layers.
