    摘要： A device for manufacturing an n-layered optical information carrier having an injection molding unit for manufacturing a carrier body with a first information layer, and furthermore, a first embossing unit for manufacturing a second information layer. The second information layer has an input via which information carriers can be received in the embossing unit. The embossing unit moreover has an output unit via which the coated information carriers are output. (n−2) additional embossing units are associated with the device, for manufacturing in each case an additional information layer, wherein “n” is greater than two. The respective units are linked to one another so that the n-layered information carrier is manufactured in an inline manufacturing. The (n−2) additional embossing units can be coupled to and uncoupled from the device, wherein the additional embossing units in each case have an input and an output unit.

    摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

    摘要： The invention relates to an optical storage medium comprising below an entrance face (EF) a higher recording stack (ST0) comprising a higher recording layer (L0) and at least a lower recording stack (ST1), said lower recording stack (ST1) being recorded or read back by a radiation beam (4) entering into the optical storage medium through the entrance face (EF) with a wavelength (λ), focused on said lower recording stack (ST1) and transmitted through the higher recording stack (ST0), a recording of the higher recording layer (L0) causing an optical thickness variation between recorded and unrecorded areas of said first recording layer (L0), which is included into the range [0.03λ, 0.125λ].

    摘要： A multi-layer recording medium is constituted by guide layer-equipped optical disks having a plurality of recording layers and guide layers are integrated by bonding said disks to one another so as to produce a double-sided disk, both sides of which may be used for recording. With regards to the lead-in areas for the guide layers of the guide layer-equipped optical disks for both sides, single-sided disks and double-sided disks are identified, and face-management information for identifying the side surfaces in the case of a double-sided disk is recorded in advance in said lead-in areas using wobbles or the like. As a result, the likelihood of the occurrence of defective products caused by the inability to read the face information can be reduced.
