摘要： Provided are a cylindrical base, a master and a method for manufacturing a master enabling a uniform transfer of a fine pattern. A cylindrical base of a quartz glass having an internal strain in terms of birefringence of less than 70 nm/cm is used. A resist layer is deposited to an outer circumference surface of this cylindrical base, a latent image is formed on the resist layer, the latent image formed on the resist layer is developed and the pattern of the developed resist layer is used as a mask for etching to form a structure including concaves or convexes arranged in a plurality of rows on the outer circumference surface of the cylindrical base.

摘要： The present invention provides a computer-implemented method and an apparatus for manufacturing an analogue audio storage medium wherein digital audio data is converted into topographical data representing an analogue translation of the digital audio data, and a laser beam is selectively applied to a substrate to form a physical imprint of the topographical data on the surface of the substrate to create an analogue audio storage medium. The medium may be directly playable on a conventional playback device such as a record player and/or used to mould further playable mediums. The invention thereby enables more efficient manufacturing of e.g. vinyl records and consistently ensures a much higher quality of analogue audio.

摘要： A device for manufacturing an n-layered optical information carrier having an injection molding unit for manufacturing a carrier body with a first information layer, and furthermore, a first embossing unit for manufacturing a second information layer. The second information layer has an input via which information carriers can be received in the embossing unit. The embossing unit moreover has an output unit via which the coated information carriers are output. (n−2) additional embossing units are associated with the device, for manufacturing in each case an additional information layer, wherein “n” is greater than two. The respective units are linked to one another so that the n-layered information carrier is manufactured in an inline manufacturing. The (n−2) additional embossing units can be coupled to and uncoupled from the device, wherein the additional embossing units in each case have an input and an output unit.

摘要： For irradiating a layer a radiation beam is directed and focussed to a spot on the layer, relative movement of the layer relative to the lens is caused so that, successively, different portions of the layer are irradiated and an interspace between a surface of the lens nearest to the layer is maintained. Furthermore, at least a portion of the interspace through which the radiation irradiates the spot on the layer is maintained filled with a liquid, the liquid being supplied via a supply conduit. At least a portion of the liquid fills up a recess through which the radiation irradiates the spot.

摘要： A method is provided for making stamper plates for an embossing drum for embossing tape media. At least one first stamper plate is formed using a master template. The at least one first stamper plate includes first land and groove patterns that are an inverse of the master template land and groove patterns. At least one second stamper plate is formed from the at least one first stamper plate. The at least one second stamper plate includes second land and groove patterns that are an inverse of the first land and groove patterns. Furthermore, the first stamper plates and the second stamper plates have four sections arranged in a travel direction of the tape media, a first and a fourth of the four sections having land and groove patterns that are laterally mirrored with respect to each other. A first stamper plate is coupled to a second stamper plate to form part of the drum for embossing tape media.
