Abstract
An optical disc recording device includes a data acquisition unit configured to acquire bitmap data corresponding to image information, an address information acquisition unit configured to acquire address information set in wobbles of an optical disc by wobble synchronization from the optical disc, a recording position determining unit configured to determine a recording position on the optical disc for recording the bitmap data using the address information, and a mark recording unit configured to form a recording mark corresponding to the bitmap data on the information recording track of the optical disc by applying a light beam having recording power to the recording position on the optical disc.
Claims12
An optical disc recording device for forming image information on a recording surface of a disc-shaped recording target medium, comprising:
- a data acquisition unit configured to acquire bitmap data corresponding to the image information;
- an address information acquisition unit configured to acquire, by wobble synchronization, from an optical disc that is the recording target medium and in which an information recording track has wobbles, address information set in the wobbles;
- a recording position determining unit configured to determine a recording position on the optical disc for recording the bitmap data using the address information;
- and
- a mark recording unit configured to form a recording mark corresponding to the bitmap data on the information recording track of the optical disc by applying a light beam having recording power to the recording position on the optical disc.
An optical disc recording method for forming image information on a recording surface of a disc-shaped recording target medium by an optical disc recording device, the method comprising:
- acquiring bitmap data corresponding to the image information;
- acquiring, by wobble synchronization, from an optical disc that is the recording target medium and in which an information recording track has wobbles, address information that is set in the wobbles;
- determining recording a position on the optical disc for recording the bitmap data using the address information;
- and
- forming a recording mark corresponding to the bitmap data on the information recording track of the optical disc by applying a light beam having recording power to the recording positions on the optical disc.
