Title: Method for controlling a spindle servo in optical disc device
Inventor: LEE DONG JU
IPC: G11B19/20
Filed: 2002-01-12
Abstract: PURPOSE: A method for controlling a spindle servo in an optical disk device is provided to safely stop a spindle motor rotating at a high speed without using an FG signal generator, thereby simplifying the optical disk device and reducing the manufacturing cost. CONSTITUTION: A spindle motor rotates at a high speed for normally executing a general data playback operation(S20). In the case of an emergency, a servo control unit controls a motor driving unit for cutting off driving voltage applied to the spindle motor(S21-S22). The servo control unit detects and confirms counter electromotive force generated from the spindle motor at a point that the driving voltage is cut off(S23). Break voltage and time corresponding to the counter electromotive force are retrieved and read(S24). The servo control unit controls the motor driving unit to apply the detected break voltage to the spindle motor(S25). It is confirmed whether a time count value counted by a time counter unit passes the break voltage apply time(S26). It is judged whether the rotation of the spindle motor is completely terminated(S27).
