摘要： Disclosed is a disc-shaped recording medium manufacturing method capable of making it difficult to leave the cutting wastage produced upon forming a notch for exfoliating a stamper on a disc-shaped substrate in the case of adopting a stamper-based transfer method, and surely forming the notch to improve a manufacturing yield. This disc-shaped recording medium manufacturing method is that a spacer layer having recording faces on both surfaces thereof is formed between the disc-shaped substrate and the stamper, a notch is formed in the vicinity of an outer peripheral edge of the stamper by a rotary blade of a circle cutter, and the stamper is exfoliated through the notch while the spacer layer stays on the disc-shaped substrate.

摘要： A surface treatment of a light transmissive layer by spin coating is carried out in a simple way at low cost. When a light transmissive layer is to be formed by spin coating, the transfer of an information recording layer is carried out using a resin stamper having a convex portion in an outer peripheral portion. At the same time, an inclined plane (concave portion) is formed on the side of a substrate (member on which transfer is performed). As a result, coating is achieved in such a manner that a raise in the outer peripheral portion is prevented from being noticeable.

摘要： Improved techniques for forming a reflective layer of an optical disc are provided. One improvement includes forming the reflective layer over an information layer of the disc by utilizing a metallizer and a masking device having an angled lip configured to align to an outer edge of the information layer. The masking device allows the applied reflective layer to extend to the outer diameter edge of the information layer, and shields plasma generated by the metallizer from reaching internal components of the metallizer. The masking device may include a pusher having a spring mechanism attached to an inner masking portion of the masking device. When the disc and the pusher are brought into relative contact with each other by application of a first force to at least one of the masking device and the disc towards the other, the pusher is spring-loaded and is pushed up into a recess of the inner masking portion, and when the first force is removed, the spring-loaded force of the pusher pushes the disc away from the masking device.

摘要： An optical recording medium has a phase-change recording layer containing Sb and Te as essential elements therefor, to which is added at least one element selected from the group consisting of Ag, Au, Cu, Zn, B, Al, Ga, In, Si, Ge, Sn, Pb, N, P, Bi, La, Ce, Gd, and Tb, the recording layer being capable of assuming an amorphous phase changed from a crystalline phase by the application of a laser beam thereto, thereby optically recording information. Recording marks are formed in the recording medium by converting a light emission wave of laser beam into a recording pulse train comprising a plurality of on-pulses and off-pulses, with a recording frequency being continuously changed corresponding to the location of each of the recording marks in the radial direction of said recording medium. A recording apparatus has laser beam driving circuit means, signal generation means, and signal transmission means for achieving the above recording method.
