摘要： A highly reliable optical disk apparatus adapted to record and reproduce the information in and from plural types of optical disks is disclosed. An acquisition unit acquires a predetermined signal from the reflected light obtained by radiating a predetermined laser on each of the optical disks. A comparator compares the waveform of the signal acquired by the acquisition unit with the comparative waveform of the signal stored in a memory beforehand and obtained from the radiated laser corresponding to the optical disk. An identification unit identifies the type of the optical disk based on the result of comparison by the comparator.

摘要： A multi-layer disc medium includes two or more reproducing or recording and reproducing layers. One or more layers have a layer information area portion formed by at least a part of a circular path extending circumferentially of the layer. The circular paths have a center coincident with a center axis of rotation of the disc medium and are at substantially identical radial positions from the center axis of rotation of the disc medium. Layer information capable of identifying a layer concerned is disposed on at least the part of the circular path on the layer. By reading the layer information at an inter-layer transference, verification of an accessed layer can be performed simply and quickly, leading to a simple and quick inter-layer transference.

Further, it becomes possible to provide a manufacturing method capable of manufacturing a highly reliable light-emitting device and comprising the steps of forming a resist layer on a light-emitting element wafer having a plurality of light-emitting surfaces, masking portions of the resist layer just above the light-emitting surfaces, removing the resist layer except the masked portions, and shaping the resist layer into lenses.
