Abstract
A record disc reproducing apparatus, which can be used for searching for a desired track location rapidly, including a pick-up device for reading data from the disc and which is movable is a radial direction with respect to the disc and a driver for driving the pick-up device radially with respect to the disc. The moving velocity of the pick-up device is detected and used to produce a velocity signal corresponding to the moving velocity. A kick signal is generated to energize the driver and is controlled so that the velocity signal approaches a predetermined reference velocity value. During track seeking the apparatus eliminates or removes the effects of phase compensation used during reproduction.
