Patent ID: 8547812

Claim:
An optical disc device, comprising: an optical pickup part for performing a focus search on an optical-disc recording medium once the optical-disc recording medium has been mounted in the optical disc device; a determination circuit part for determining a type of the mounted optical-disc recording medium on the basis of results of the focus search; an optical-output-setting circuit part for setting in the optical pickup part, when the determination circuit part has determined that the mounted optical-disc recording medium is a multilayer optical-disc recording medium having three or more recording layers, a playback power for an optical-disc recording medium being of a specification identical to the multilayer optical-disc recording medium and having one or two recording layers; and a playback-controlling circuit part for using a playback operation at the playback power set by the optical-output-setting circuit part to read optical disc information from the mounted optical-disc recording medium, the optical disc information indicating the type of the mounted optical-disc recording medium.
