Patent ID: 7639577

Claim:
A method for recording data on an optical recording medium via a recording apparatus including an optical pickup unit and a controller, the method comprising: determining, via the optical pickup unit under control of the controller, whether a recording condition data for a current recording device is present on a specific area of the optical recording medium; and selectively recording, via the optical pickup unit under control of the controller, the recording condition data for the current recording device based on the determination, wherein the recording is performed if there is no recording condition data for the current recording device, said selectively recording step including: reading out, via the optical pickup unit under control of the controller, a reference recording condition information recorded on the specific area of the optical recording medium, the reference recording condition information including a reference recording power value, recording, via the optical pickup unit under control of the controller, test data while varying a recording condition with respect to the reference recording condition information, obtaining, via the controller, an optimum recording power, based on reproduction characteristics of the test data, and recording, via the optical pickup unit under control of the controller, the recording condition data for the current recording device on the specific area of the optical recording medium, the recording condition data including an identification of the current recording device, the optimum recording power and write strategy to be used or used to record main data other than the test data on the recording medium, wherein the optimum recording power and the write strategy of the recording condition data are distinguished by different recording speeds.
