Patent ID: 7898932

Claim:
An optical disc recording device in which an optical disc is provided, the optical disc having a sector structure comprising a header region at which address information is previously recorded, and a data recording region for recording data, wherein the header region comprises a plurality of address regions, wherein the address information comprises an address mark section at which an address mark indicating the start of the address information is recorded, and an address section for recording an address, the address information being recorded in each of the plurality of address regions, wherein the data recording region comprises a first recorded data non-referring region, a recorded data referring region, and a second recorded data non-referring region, and wherein the data is recorded into the data recording region by irradiating laser pulses to the data recording region of the optical disc, the optical disc recording device comprising: an address mark detecting unit for detecting the address mark recorded in the address mark section of each of the plurality of address regions for a particular sector; a data recording determining unit for determining a period for recording data into the data recording region of the particular sector based on a timing of detecting the address mark recorded in each of the plurality of address regions for the particular sector; a test light emission pattern generating unit for generating test recording data for determining an irradiation power of the laser pulses; and a data recording unit for recording the data into the recorded data referring region, wherein it is determined whether or not to output the test recording data to the first recorded data non-referring region according to the timing of detecting the address mark recorded in each of the plurality of address regions for the particular sector.
