摘要：An apparatus for reproducing information recorded on an optical disc which can favorably accomplish a time base correction for a read signal in a simple configuration. Also, the apparatus precisely removes jitter components produced when a driving signal is supplied to a spindle motor. The apparatus has a spindle motor for rotating an optical disc, a pickup for optically reading a recorded signal on the optical disc to generate a read signal corresponding to the recorded signal, and an A/D converter for digitizing the read signal to reproduced an encoded signal. The apparatus is provided with a controller for supplying the spindle motor with driving power. The controller has an unnecessary component removing filter for removing high frequency components from the motor driving power.
