Patent ID: 7382707

Claim:
A recording apparatus for an optical disk drive, comprising: a driver being capable of controlling the rotation speed of the optical disk drive; a temperature sensor connected to an optical pickup head of the optical disk drive for generating a temperature signal of the optical disk drive; a microprocessor, comprising: a detection mechanism for detecting the temperature signal and the write power of the driver as determination indices; a recording termination control mechanism for stopping recording if at least one of the determination indices exceeds a preset threshold value; and a recording speed adjustment mechanism for setting parameters with a lower rotation speed if at least one of the determination indices exceeds the preset threshold value; and a maximal write power estimation mechanism for checking the maximum value of write power during the recoding process according to the result of optimal power calibration (OPC); and a digital signal processor for converting the parameters with the lower rotation speed into a driving signal that instructs the driver to decrease the rotation speed of the optical disk drive.
