Method for generating control parameters for optimum write power and apparatus therefor

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.
