摘要： An optical disc for use as a compact disc, an optical video disc, or the like has a disc substrate of a light-transmissive material such as polycarbonate, PMMA, or the like. The disc substrate has a pattern of pits and lands formed as representing an information signal on at least one surface thereof. A thin reflective layer of a-corrosion-resistant metallic material such as an alloy of Fe, Ni, and Co is deposited on the disc substrate over the pattern of pits and lands. The optical disc is relatively inexpensive to manufacture as no protective layer needs to be deposited on the reflective layer and is also highly resistant to loss of performance with aging because the reflective layer is made of a corrosion-resistant metallic material.
摘要翻译： 用作光盘的光盘，光学视频盘等具有诸如聚碳酸酯，PMMA等的透光材料的盘基片。 盘基片具有在其至少一个表面上形成为表示信息信号的凹坑和平台的图案。 在凹坑和焊盘的图案上，在光盘基板上沉积耐腐蚀金属材料的薄反射层，例如Fe，Ni和Co的合金。 光盘的制造相对便宜，因为不需要在反射层上沉积保护层，并且由于反射层由耐腐蚀金属材料制成，所以它也具有耐老化性能的高性能。

摘要： A molding and film forming apparatus 700 molds a disc substrate from a stamper 330 formed from an optical disc disc-master 320 and forms a coating film, for example, a reflective film onto the disc substrate, thereby forming a recorded optical disc 360. A postscript apparatus 200 writes postscript information once onto an optical disc 340 formed by the molding and film forming apparatus 700. As postscript information, a laser beam is irradiated to a predetermined interval of the optical disc 340, a portion which is detected as a pit is formed, and an optical disc 350 on which postscript information 420 has been recorded is formed. Identification information which enables each optical disc 340 to be identified can be postscribed. The postscript information is recorded in a conventional format and the postscript information can be reproduced by an existing reproducing apparatus.

摘要： In a process of manufacturing a disc master, a stamper, a disc substrate, and an optical disc, separation performance between the stamper and the disc substrate and maintenance of satisfactory signal characteristics after the optical disc is manufactured are taken into consideration in the step of manufacturing the disc master. In the disc master, a boundary portion between a recessed portion and a non-recessed portion includes a small protrusion which protrudes from a flat surface of the non-recessed portion. The shape of the disc master is inversely transferred to the stamper, and the shape of the stamper is inversely transferred to the disc substrate. The separation performance is improved and the signal characteristics are maintained due to the shape of the boundary portion.
