Temperature compensation method for laser power of an optical disk drive

[0018]The technologies and methods used to achieve the above objects of the invention are exemplified in the following preferred embodiments with accompanying drawings.

[0019]Referring to FIG. 2, a linear-fitting power curve of a temperature compensation method for laser power according to a preferred embodiment of the invention is shown. The invention obtains the optical disk drive linear-fitting power curve by use of practical measuring and curve fitting. Firstly, an optical disc drive is tested at different temperatures. In the present embodiment of the invention, the temperatures 35° C., 40° C., 45° C., 50° C., 55° C., and 60° C. are used as examples. When the optical disk drive is controlled to operate at a particular temperature and a plurality of different voltages (or currents) are respectively inputted to the laser diode, an output of laser power corresponding to each input voltage is detected and the testing result is recorded, and several test points are formed on the coordin
