Patent ID: 7995436

Claim:
A recording device for performing recording supporting an optical disk-shaped recording medium having a laminated structure including a first recording layer and a second recording layer, said recording device comprising: a recording section configured to record data in said first recording layer and said second recording layer by irradiating the optical disk-shaped recording medium with laser light; a recording control section configured to control said recording section so as to perform recording in said first recording layer first and next perform recording in said second recording layer when the recording is performed sequentially on the optical disk-shaped recording medium; a pseudo defect area setting section configured to, when a real defect area is detected in the first recording layer while said recording section is recording data in said first recording layer, set a pseudo defect area in said second recording layer, said pseudo defect area including a corresponding area corresponding to the detected real defect area in the first recording layer in physical positional relation, a first margin area continuing from a start position of the corresponding area to a first boundary position and a second margin area continuing from an end position of the corresponding area to a second boundary position, the first and second margin areas being set such that, when the second recording layer corresponding to the first and second boundary positions is irradiated with a laser spot in a focused state, the real defect area is not irradiated with the laser spot; and a defect registering section configured to register said real defect area and said pseudo defect area as a defect area; wherein said recording control section controls the recording section so as to prevent data recording from being performed in a defect area registered by said defect registering section.
