Abstract: PURPOSE: A device of compensating for a tilt is provided to measure an amount of tilt of an optical recording medium, and to perform a tilt compensation process only when the measured amount exceeds a reference tilt, thereby reducing a lead-in time while driving a tilt. CONSTITUTION: When an optical recording medium is inserted, a DSP(200) measures an amount of a tilt of the medium. If the measured amount of the tilt exceeds a reference tilt, the DSP(200) outputs a tilt compensation signal and outputs a control signal for turning on the first and second switching portions(201-1,201-3). The first switching portion(201-1) switches the tilt compensation signal on. The switched tilt compensation signal is transmitted to the first drive IC(202). The first drive IC(202) generates the tilt compensation signal, and outputs the signal to an optical pickup(203). A phase inversion portion(201-2) inverses a phase of the tilt compensation signal. The second switching portion(201-3) switches the inversed tilt compensation signal on, and outputs the signal to the second drive IC(201-4). The second drive IC(201-4) outputs the generated tile compensation signal to the optical pickup(203).
