Abstract
A signal conditioning unit processes a data signal from an optical pickup unit. The signal conditioning unit includes a single-ended channel and a dual-ended channel. One of the single-ended channel and the dual-ended channel is selected as an active channel, and a reference level of a signal in the active channel is calibrated. The signal in the active channel is adjusted within a dynamic range of a digital signal processing stage, and the data signal of the active channel is converted to a digital signal at the digital signal processing stage.
