Abstract
A recording device for performing recording supporting an optical disk-shaped recording medium having a laminated structure includes a first recording layer and a second recording layer. The recording device includes: a recording section configured to record data in the first recording layer and the second recording layer by irradiating the optical disk-shaped recording medium with laser light; a recording control section configured to control the recording section so as to perform recording in the first recording layer first and next perform recording in the second recording layer when the recording is performed sequentially on the optical disk-shaped recording medium; a pseudo defect area setting section configured to set a pseudo defect area in the second recording layer; and a defect registering section configured to register the real defect area and the pseudo defect area as a defect area.
