摘要： A disc-shaped optical data recording medium has a signal recording layer for reading and/or writing data using light, and a 10 μm to 200 μm thick transparent protective layer disposed over the signal recording layer. The optical data recording medium includes a protrusion projecting from a surface of the transparent protective layer on a light-incidence surface side to which light is emitted to the signal recording layer. The protrusion is disposed in an area between a center hole and a clamping area where the optical data recording medium is held when reading and/or writing data in the signal recording layer.

摘要： An optical information recording medium has tolerance to warping. The optical information recording medium includes at least one information recording layer on a main surface of a substrate and a light-transmitting layer. The substrate includes a clamp area and an information recording area in accordance with the information recording layer. In the light-transmitting layer, the average thickness of a second area corresponding to the clamp area is thinner than the average thickness of a first area corresponding to the information recording area.

摘要： An optical disc manufacturing method suppresses thickness variation in intermediate layers disposed between any two data recording layers to achieve an intermediate layer of uniform thickness. A substrate having a center hole and data recording layer is first prepared. This center hole is then plugged with a capping member and a resin material is dripped from above the center hole while spinning the substrate around its center hole to coat the data recording layer with the resin by a spin coating method. The capping member is then removed. Then, a stamper having a groove or lands and pits on its surface is prepared. The groove or lands and pits side of the stamper is then pressed into the resin material on the substrate, and the resin is then cured to form an intermediate layer. The stamper is then separated from the substrate to leave a data recording layer in the surface of the intermediate layer with a groove or land-and-pit pattern corresponding to the groove or lands and pits in the stamper.
