摘要

PROBLEM TO BE SOLVED: To provide a disc device capable of preventing the reduction of read quality in reproduction of a disc having undergone recording by a plurality of recording devices.SOLUTION: The disc device includes a selection unit and a reproduction unit. The selection unit reads data from a disc in a recorded region on the disc recorded by the same recording device as the recording device having recorded data to be reproduced of the disc, and selects an adjusted value obtained by adjusting a reading signal created from the reading (S250). The reproduction unit performs the adjustment with the adjusted value selected by the selection unit, and reproduces the data to be reproduced (S260 and S270).
