    摘要: A recording apparatus capable of recording an optical disk obtained by adhering two substrates having predetermined curvatures with the convex surfaces of the substrates being adhered, wherein a light source irradiates light through an optical set to the optical disk via a converging lens. Plural light detectors are provided for photoelectrically converting reflection light from the data recording surface of the optical disk and returning through the optical set to output respective signals corresponding to a difference in distance between the lens and the data recording surface, a difference between the center of a light beam spot formed at a focal point position of the lens in a center of either one of a track and a pit line on the data recording surface, and a degree of tilt of the data recording surface. Lens movement mechanisms are provided to move the lens perpendicular and parallel to the data recording surface and to cancel the tilt. The signal recording on the disk is reproduced and output from the apparatus.

    摘要: An improved substrate and stamper holder and method of forming substrates are disclosed. According to a preferred embodiment of the invention, a substrate for a DVD has a moat with a capillary barrier shape. Under one embodiment, the moat has a region with an abrupt outer diameter transition. One embodiment has the outer diameter transition at approximately at a right angle relative to a registering surface of the substrate. Another embodiment of the invention provides a wider moats. The improvements reduce the likelihood of resin wicking past the moats.

    摘要: Method and apparatus for producing a bonded composite disk including a first and a second disk component which are bonded together, using a mold including a first mold half having first concentric elements whose axial end faces cooperate with an annular information-bearing stamper or an annular blank stamper, to provide a first molding surface, and a second mold half having a second concentric elements whose axial end faces provide a second molding surface cooperating with the first molding surface to define a cavity for forming each of the first and second disk components. The diameters of first annular boundaries between the end faces of the adjacent first concentric elements are different from those of second annular boundaries between the end faces of the adjacent second concentric elements, and the first disk component formed with the information-bearing stamper set on the first mold half is bonded at a first bonding surface formed by the first molding surface to a second bonding surface of the second disk component that is formed by the second molding surface with the blank stamper set on the first mold half.
