摘要： A data storage medium is provided which is suitable for production or replication by moulding, casting, embossing or a similar process against a tool. The data storage medium comprises an optically sensitive layer at or adjacent to one surface of the medium, said one surface of the medium comprising a plurality of topographical features or structures disposed in a regularly repeating pattern, said pattern being free from undercutting so that the medium can be produced and/or replicated by molding, casting, embossing or similar process against a tool. The optically sensitive layer is preferably overcoated with a thin film of a metallic material which conforms to the topography of said surface.

摘要： A data storage medium is provided which is suitable for production or replication by moulding, casting, embossing or a similar process against a tool. The data storage medium has a surface or a surface region which is strongly absorbent of at least a predetermined band of wavelengths of electromagnetic radiation. The surface or surface region includes a layer of a material which undergoes a large volume change or degradation and has a regular, sinuous textured surface pattern which is free from undercutting. The textured surface pattern is coated with a thin film of platinum or a platinum alloy, the thickness of the overcoating preferably being such as to give no more than 10% transmission of incident radiation.A method of storing information on such a data storage medium is also disclosed. The data storage medium may be prepared in blank form for use as the consumer desires, or it may be pre-recorded in part or in entirety.

摘要： Optical data storage members in which the guard bands present between data-carrying tracks of conventional data storage members are used to carry information recorded in a manner which avoids the danger of cross-talk between adjacent tracks. One preferred arrangement consists of an optical data storage member comprising an optically recordable surface having a plurality of tracks in which information may be recorded in analogue or digital form, the tracks being of a first type in which the material constituting the track is sensitive to radiation of a first predetermined characteristic and a second type in which the material thereof is sensitive to radiation of a second predetermined characteristic, wherein tracks of the first type alternate across the surface of the second type. The tracks may be constituted by a surface region (1,2,3,4,5) carrying a plurality of closely spaced grooves (11,12,13,14,15), the grooves of one track being orthogonally directed with respect to those of its adjacent tracks. The predetermined radiation characteristic can be the polarization state of the incident radiation.

摘要： In a method of manufacturing a diffraction grating, the grating-bearing surface of a master grating is coated with a release agent, and a rigid substrate has a layer of ultravoilet sensitive liquid resin applied thereto before bringing the master grating and the substrate together to trap a film of the liquid resin therebetween, whereafter the liquid resin is cured by exposure to ultraviolet light through the master grating and the master grating and resin-profiled substrate are separated prior to completion of the diffraction grating by deposition of a thin metal film on the resin-profiled surface of the substrate.

摘要： An improved optical data storage medium is reponsive to incident electromagnetic radiation, and the surface or a surface region of the medium includes a layer of heat sensitive material which has a textured surface pattern in the form of a regular array of grooves or protuberances, the dimensions of the surface features which constitute said textured surface pattern being in the sub-micron range. The textured surface pattern is overcoated with a thin film of an alloy, said alloy comprising (1) a first component which is at least one of ruthenium, rhodium, palladium, osmium, iridium and platinum; and (2) at least one other metallic element, preferably from Groups Va, VIa, VIIa, and Ib of the Periodic Table of elements according to Mendeleev.The preferred alloy compositions for such data storage media contain platinum and tungsten. Specific alloy compositions based on platinum/tungsten are also provided, as is the use of certain alloy compositions in providing an overcoating layer for optical data storage media.

摘要： A method of reducing the surface noise of optical disk products of the type having a surface relief pattern is disclosed. In one embodiment, an adherent layer is applied to the substrate of the disk before it is coated with the recording material layer. In another embodiment, a polymeric replica produced from a master disk is treated by spin coating or dipping in a weak solvent which serves to smooth out microscopic roughness thereby removing surface irregularities. In a third embodiment, a metal coated replica is subjected to an electropolishing operation which again serves to remove a small amount of metal material, preferentially from "high spots".

摘要： A pre-formatted optical data storage member is described in which format zones are generated by the provision in the surface of the optical medium of a "moth-eye" structure, i.e. regular surface pattern in the form of an arrangement of grooves or protuberances. The pitch and depth of the pattern is such that when irradiated with illumination of predetermined optical characteristics, the format zones display a reflectivity substantially lower than that of the remainder of the optical storage member. Methods of producing optical data storage members with such pre-formatting are also described.
