ABSTRACT:
A spindle motor controlling apparatus having a motor driving device, a motor speed controlling device, a MICOM and an image processing device uses a horizontal synchronization comparing device which detects a horizontal synchronization signal of the image processing device and compares the detected synchronization signal with a reference synchronization signal and applies the compared signal to the MICOM. The motor driving device further includes a switching part for providing power according to the control signal of the MICOM to the spindle motor.
