APPARATUS AND METHOD FOR COMPENSATING TRACKING ACTUATOR SENSITIVITY |
摘要 |
PURPOSE: A device for compensating for sensitivity of a tracking actuator and a method thereof are provided to accurately print images printed on a label surface of an LSD(Light Scribe Disc) at a fixed track interval. CONSTITUTION: A memory(20) stores a function value of a quadratic equation. The function value is for compensating for sensitivity of a tracking actuator per a focus location of an optical pickup. A microcomputer(15) checks a focus location of an optical pickup while a label is printed on an LSD. The microcomputer substitutes the checked value with the function value of the quadratic equation. The microcomputer compensates for sensitivity of a tracking actuator.
