An apparatus and method for controlling spindle motor of compact disc utilizing appliance are disclosed, in which the spindle motor is controlled early to meet a rotation speed on a target track, in a rough search, so that a phase locked loop (PLL) servo is normally operated, immediately after the search, thereby enabling the time required in accessing information to be reduced. The apparatus includes a device for detecting the rotation speed of the spindle motor. In the search mode, the frequency corresponding to the detected rotation speed of the spindle motor is compared with a reference frequency corresponding to a rotation speed on the target track. A signal indicative of the comparison result is differentially amplified, to control the spindle motor to correspond to the rotation speed on the target track, in the search mode. After a compact disc has been loaded, the rotation speed in a track corresponding to a reference position at which a reference value is set is detected, so that the inherent deviation in constant linear velocity is calculated, based on the reference value, and corrected upon calculating the number of tracks.
