Patent ID: 7480221

Claim:
An apparatus for generating control parameters for optimum write power to be used in an optical recording system to control an optical read/write head thereof to generate an optimum write laser power based on the control parameter for performing data recording on an optical recording medium, said apparatus comprising: a write voltage generating unit connected to the optical read/write head for generating a write voltage to drive the optical read/write head to correspondingly output a write laser power; a control unit connected to said write voltage generating unit for controlling said write voltage generating unit to generate a plurality of write voltages of different levels so as to drive the optical read/write head to generate different write laser powers for recording data on a plurality of continuous write intervals of the optical recording medium; and a detecting and computing unit which is connected to the optical read/write head, which is controlled by said control unit to detect a peak value, a first level, and a second level of a write reflected signal generated by each of the write intervals of the optical recording medium during recording for performing an arithmetic operation so as to obtain a first control parameter of each write interval, and which is controlled by said control unit to detect a peak value, a bottom value and a direct current level of a read reflected signal generated by each of the write intervals when being read for performing an arithmetic operation so as to obtain a second control parameter of each of the write intervals.
