Abstract
An apparatus for determining an information record medium is provided. The apparatus includes an emitting device, a light receiving device and a determining device. The emitting device respectively emits a plurality of light beams whose wave lengths are different from each other. Then, the light receiving device receives respective reflection lights from an information record medium of the emitted respective light beams, and outputs light reception signals respectively corresponding to the received reflection lights. After that, the determining device determines a type of the information record medium in accordance with a ratio between the outputted respective light reception signals.
