Description

technical field

[0001] One aspect of the present invention relates to an optical recording device, and more particularly, to a technique capable of reducing deviation and increasing speed of an Optimum Power Calibration operation. Background technique

[0002] In an optical recording / reproducing apparatus, it is important to record information on an optical recording medium using an irradiation beam with precise power. Due to the environment of all recording media and recording equipment combined and the influence of equipment-to-equipment deviations, such precise power cannot be provided basically all the time (for example, by pre-recording on the disc)

[0003] Therefore, in order to find the optimal optical power suitable for the recording operation, the optical recording / reproducing device generally performs an Optimum Power Calibration (Optimum PowerCalibration) operation in a test area of ​​an optical disc inserted therein to detect the optimal optical power (Popt), an...
