Abstract
A tilt adjusting apparatus including a digital signal processor, a first drive integrated circuit, and a tilt adjuster. When an optical recording medium is loaded into a deck, the digital signal processor outputs a focus control signal to control a focus of an optical recording medium, measures a tilt with respect to the optical recording medium, and outputs a tilt adjustment signal and a switch control signal so as to adjust the tilt. The first drive integrated circuit either synthesizes the tilt adjustment signal and the focus control signal or receives only the focus control signal according to the switch control signal and then outputs the synthesized signal or the focus control signal to the optical pickup. The tilt adjuster synthesizes the tilt adjustment signal output from the first drive integrated circuit and the focus control signal and then outputs the synthesized signal to the optical pickup.
