摘要： An invention disclosed includes a layer number obtaining section (222) for determining which information storage layer (L1) has been accessed and a layer type identifying section (223) for identifying a type of the information storage layer (L1) determined by the layer number obtaining section (222). With the configuration, even in a case where an information recording and reproducing apparatus accesses an information storage layer different from an intended information storage layer by false operation or the like, it is still possible to dissolve mismatching between a recording or reproduction control scheme being set up and a recording or reproduction control scheme suitable for the information storage layer thus accessed.

摘要： An optical information recording medium (1) includes, on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a cover layer (10) provided in a position farthest from the substrate (50). The RE layer (40) is an information recording layer provided in a position farthest from the light transmitting layer and also is a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier determination as compared to an information recording format used in the layer allowing only readout of information by use of light irradiation.Therefore, it becomes easy to check a disc type in a recording/reproducing device and one recording/reproducing device can be shared with other types of optical disks. Further, disk production becomes easy. In addition, it becomes possible to obtain an optical information recording medium that makes it possible to replace outdated data in the ROM layer by recording, in the RE layer, updated data obtained at the time when net connection can be established.

摘要： There is provided a storage layer (13) between storage layers (11), (15). The storage layer (13) produces a relatively large spherical aberration for a protection layer thickness error. Information is written to or read from the storage layer (13) with a beam of light having a second wavelength. Information is written to or read from the storage layers (11), (15) with a beam of light having a first wavelength (longer than the second wavelength). Accordingly, a multi-format optical storage medium is realized on which information can be recorded or reproduced with a single objective lens. Also, an optical pickup is realized which is capable of recording or reproducing information on the multi-format optical storage medium.
