摘要： The invention is directed toward techniques for creating molded substrates for use in various different data storage media. The molded substrates have improved thickness profiles that can improve media quality, and in some cases facilitate higher data storage densities. In many cases, the improved thickness profile is a thickness profile that has improved flatness. Mechanical flatness or optical flatness can be achieved. In particular, optical flatness is desirable for substrates used in holographic data storage media having a sandwiched construction.

摘要： An optical disk exhibiting no detrimental thickness increase (edge wedge effect) that arises at the outer diameter of an optical disk substrate during an injection molding manufacturing process, and an apparatus and method for making such a disk. The optical disk of the present invention is designed for use with an optical disk player, especially where the data on the optical disk is stored air incident. This optical disk includes a disk substrate made from a molded polymeric material. The disk substrate has a first major surface, a second major surface, and an outer edge. The first major surface of the optical disk includes a data region having an intermediate portion and an outer portion. The outer portion extends to the outer edge of the optical disk. The disk substrate has a thickness defined by the distance between the first major surface and the second major surface. The optical disk also includes an information layer covering the data region. In the present invention, the thickness of the intermediate portion of the data region is substantially equal to the thickness of the outer portion of the data region such that the outer portion of the data region is capable of being used by the optical disk player.

摘要： Imperfections in the surface of information carrying discs, such as video discs, are avoided by an improved process of manufacture. A bead of photopolymerizable mass is moved between two surfaces, one of which is a patterned surface and the other is a surface to which the photopolymerizable mass will bond upon polymerizing. By moving the liquid mass across the patterned surface, air within the pattern is removed by the leading edge of the bead, reducing imperfections.

摘要： In one embodiment, the invention is directed to a manufacturing process for optical data storage disks that makes use of a check disk very early in the production cycle. The check disk can be replicated directly from the master without destroying the master. The check disk may then be tested in order to validate the pattern created on the master. In some cases, the check disk may be delivered to customers, allowing the customers to verify the check disk. Once the check disk has been verified, the master can be used to create one or more stampers, which can be used in a mass production process for creating optical data storage disks. However, if the check disk is defective or otherwise not acceptable, the production cycle can be halted prior to creating any stampers. In this manner, the invention can be used to avoid creation of defective stampers or other defective mass production tools.

摘要： The invention is directed toward techniques for stamping optical data storage disks. A master is first created to include several distinct information regions etched upon a master surface. The master is then used to create one or more stampers. The stampers include a number of distinct stamper regions in locations corresponding to locations of the distinct information regions on the master. The stamper is then used to create a number of first replica disks that include distinct replicated regions. The distinct replicated regions are removed from the first replica disks to define second disks.

摘要： Disclosed is a stamper assembly for forming an optical data storage disk in a disk molding process. The stamper assembly includes a block element having a first major surface, and a stamper member having a first major surface and an opposite, second major surface. The first major surface of the stamper member is adapted to contact a disk molding material for forming an optical data storage disk in a disk molding process. The stamper assembly further includes a medium for securing the stamper member to the block element, such that substantially the entire second major surface of the stamper member is affixed to the first major surface of the block element. This arrangement prevents relative movement between the stamper member and the block element. This substantially reduces stamper member wear and increases the useful production lifetime of the stamper assembly. The stamper assembly is useable in a mold assembly either by itself or with another like stamper assembly to form either single-sided or double-sided optical data storage disks.
