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.

摘要： A record disc reproducing apparatus, which can be used for searching a desired track location rapidly, includes a pick-up device for reading data from the disc and movable in a radial direction with respect to the disc. A velocity detector detects a moving velocity of the pick-up device and produces a velocity signal corresponding to the moving velocity. An integrator integrates the velocity signal. A distance that the pick-up device should be moved is calculated according to addresses of a track presently scanned by the pick-up device and a track to be searched. A generator supplies a distance data corresponding to the distance calculated. A comparator compares the integrated velocity signal with the distance data. The pick-up device is stopped when the comparator produces an output signal.

摘要： An amplifier includes a differential amplifier which is supplied with a small amplitude signal in a normal condition and a large amplitude signal in an abnormal condition. Resistors and diodes jointly act to judge whether the differential amplifier issues a small or large amplitude signal. A small amplitude signal is amplified by a small amplitude signal-amplifying section and a large amplitude signal is amplified by a large amplitude signal-amplifying section. The large amplitude signal-amplifying section is supplied with a first source voltage B.sub.2. The small amplitude signal-amplifying section is impressed with a second source voltage B.sub.1. An output signal of the amplifier is supplied to a load A through an output terminal common to the small amplitude signal-amplifying section and large amplitude signal-amplifying section. The first and second source voltages B.sub.2, B.sub.1 are chosen to have the following relationship:B.sub.2 >B.sub.1.
