Abstract
A read circuit for a disc player or the like is provided that can achieve a high-speed data recovery, which can be varied by increasing only a clock speed. The read circuit can include a control signal generating unit receiving a radio frequency signal detected from a disc and outputting first and second control signals to an external circuit and outputting first and second output signals. A level compensating unit receives the first output signal from the control signal generating unit and feeds back a level compensation control signal to the control signal generating unit. A gain compensating unit receives the second output signal from the control signal generating unit to feed back a gain compensation control signal to the control signal generating unit to compensate a gain of the control signal generating unit. A timing control unit receives the second output signal from the control signal generating unit and feeds back a timing control signal to the control signal generating unit.
