Patent ID: 7379403

Claim:
A tilt adjustment apparatus to adjust a tilt of an optical pickup unit relative to an optical recording medium when the optical recording medium is loaded into a deck, comprising: a tilt adjustment button on which a tilt adjustment signal is input to perform a tilt adjustment operation, regardless of the tilt of the optical pickup unit relative to the optical recording medium; a digital signal processor to receive the tilt adjustment signal from the tilt adjustment button and output a focus control signal to control a focus of the optical recording medium and output the tilt adjustment signal; a first drive integrated circuit to receive and synthesize the tilt adjustment signal and the focus control signal from the digital signal processor and output the synthesized signal to the optical pickup unit; and a tilt adjuster to receive and synthesize the tilt adjustment signal and the focus control signal from the first drive integrated circuit and output the synthesized signal to the optical pickup, wherein when the tilt adjustment signal is input via the tilt adjustment button, the optical recording medium stops reading and an automatic tilt adjustment operation is performed.
