| description | PROBLEM TO BE SOLVED: To provide a computer readable storage medium on which a computer program is recorded for making a computer carry out the control of the power of a laser beam used in texturing a disk. SOLUTION: An optical system for providing textured spots in an annular portion of the disk includes a laser directed at a beamsplitter to split the laser beam into two beams having approximately power. The two beams are directed along parallel paths through a power control optics block to expose simultaneously both sides of the disk to be textured. The power level of each of these two beams is controlled by a program which operates in a teach mode to develop look up table describing laser beam power as a function of a signal driving an attenuator, in a set point mode setting this driving signal to provide a certain laser beam power, in a run mode controlling this power through a feedback loop, and in a display mode showing laser beam power as a function of time. |
