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.
