摘要： An optical recording disc comprises a first bonding recess formed near an outside surface of an optical recording disc in a bonding boundary portion between a cylindrical hub and a transparent disc substrate, a disc member bonded with said transparent disc substrate through said cylindrical hub, and a second bonding recess formed near the outside surface of said optical recording disc in a bonding boundary portion between said cylindrical hub and said disc member. Accordingly, said optical recording disc can prevent remainder of a bonding material for bonding a pair of said transparent disc substrates or said transparent disc substrate and said disc member together from pushing out of the outside surface of the optical recording disc, resulting in that focusing for reading and writing an information signal can be properly performed.

摘要： A disc-shaped information carrier (1) is formed by welding two injection-moulded plastics discs concentrically to each other (1A, 1B), which discs are manufactured by means of a method comprising the manufacture of a matrix (9), which matrix is formed with recesses (6) which form projections (5A, 5B) on the disc during injection-moulding and which are fused to the facing disc during welding. Said recesses are formed in the matrix by pressing an indenter pin (7) having a pointed end (8) into the matrix surface, to form locally pit-shaped recesses each surrounded by a ridge (11) of displaced material, which ridge has a volume which is substantially equal to the volume of the pit-shaped recess, so that during injection-moulding the disc is provided with a corresponding pin-shaped projection which is surrounded by a groove (12) which can receive the volume of that part of the pin which is melted during welding.

摘要： A holographic data storage medium is provided, which includes a first substrate; a second substrate which has a dimension larger than that of the first substrate; and a holographic-recording layer which is provided between the first substrate and the second substrate; wherein the second substrate has a support portion which is disposed outside the first substrate and which is supported by the recording/reading apparatus. The holographic data storage medium makes it possible to realize the miniaturization and the optimization of the structure of the holographic data storage medium having an outer edge portion to be held in a recording/reading apparatus and to record and reconstruct information more correctly.
