Patent ID: 8295136

Claim:
An optical recording device for recording information on an optical recording medium having a plurality of recording layers by irradiation with laser light, comprising: a target value reading unit that reads a standard target value for calibrating recording power from the optical recording medium or from within the optical recording device, the standard target value being determined in advance for each class of optical recording medium; a recording power calibration unit that calibrates the recording power by performing a test write in a recording power calibration area provided in a recording layer having an information recording area; an information recording unit that records information on the recording layer having the information recording area, by use of the recorded power calibrated by the recording power calibration unit; a recorded state discrimination unit that determines a recorded state of one or more shallower recording layers in front of the recording layer to be recorded by the information recording unit, as seen from a laser light incidence side in a position corresponding to the recording power calibration area; and a target value correction unit that corrects the standard target value to generate a corrected target value, based on a difference in a reproduced signal parameter between a first recorded state of one or more shallower recording layers in front of a recording layer in which test data is to be recorded, as seen from a laser light incidence side, and a second recorded state of the shallower recording layers, and on the recorded state as determined by the recorded state discrimination unit; wherein the recording power calibration unit calibrates the recording power by use of the corrected target value.
