摘要： An optical disk comprises a substrate, on one side of which a first recording layer and a second recording layer of different reflectivities are formed one on another, and a protective coating is provided on the first or second recording layer, which is farther from the substrate. For reproduction, a light beam is emitted from a single light source to the first or second recording layer through a single object lens. Based on whether the light beam is reflected from the first or second recording layer, the object lens is moved along its optical axis and focused on the recording layer to reproduce information.

摘要： A data recorded medium having a data recorded area where digital data including literary work data on literary works such as a music composition and an image is recorded, wherein identification information for identifying the recorded medium is recorded in an identification information recorded area and judging information representing presence/absence of identification information is recorded in a read-in area. The location of the digital data recorded on a recorded medium is managed by identification information for identifying the recorded medium and hence a wide variety of use such as copyings of literary work data is possible.
