Patent ID: 7385886

Claim:
An optical disk drive, which controls a spindle motor, comprising: a pickup reading data from a disk and outputting the read data in the form of a radio frequency signal; a radio frequency signal processor generating at least one of a tracking error signal and a focusing error signal from the radio frequency signal; a servo processor operating at least one of a tracking servo and a focusing servo based on at least one of the tracking error signal and the focusing error signal; a level detector detecting a level of the generated tracking error signal; a motor processor providing a motor driving voltage; a spindle motor rotating the disk at a speed corresponding to the motor driving voltage supplied from the motor processor; a reproducing stop request part outputting a reproducing stop request signal to stop the disk; and a main controller performing at least one function including stopping the tracking servo on receipt of the reproducing stop request signal, supplying the spindle motor with a brake driving voltage to stop the spindle motor, and stopping the focusing servo if a brake level of the generated tracking error signal detected after the brake driving voltage is supplied is equal to or less than a predetermined stop threshold tracking error signal value, wherein the main controller controls the motor processor to supply the spindle motor with the brake driving voltage in proportion to a predetermined gain for a predetermined time when the tracking servo is stopped.
