Apparatus for preventing damage of actuator coil in optical disc system and method for the same

摘要

An apparatus to prevent damage of an actuator coil installed in a pickup and a method for the same. The method includes: generating a servo control signal from focus and tracking error signals generated from an optical pickup; detecting a peak value of the generated servo control signal; determining whether or not an oscillation status of the focus/tracking error signal by comparing the peak value of the servo control signal to a threshold value; and if it is determined that the servo control signal is in the oscillation status for a predetermined time, cutting off a servo operation for a predetermined time by generating a servo off command
