摘要： A data storage medium 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 heat sensitive or radiation-sensitive material which has a textured surface pattern the pitch of which is smaller than the shortest wavelength of the predetermined band of wavelengths, and the depth (peak-to-trough) of which is at least 100 nm. The surface pattern is free from undercutting, and can comprise an array of protuberances or one or more sets of grooves (which may be intersecting). The textured surface is of high opacity or absorbance at least at, and just below, the surface which in use is to be exposed to writing radiation. A filled plastics material, e.g. PVC filled with carbon black, may be used. Alternatively, a layer of a dye polymer may be used. A tool for use in producing such a data storage medium, and methods of using the tool, are 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 optical data storage member with tracks of the second type. The tracks may be constituted by a surface region (1, 2, 3, 4, 5) carrying a plurality of closedly 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 polarisation state of the incident radiation.

摘要： An optical data storage medium for use in an optical read/write system using an optical read wavelength of W, the medium including a textured region having raised areas and depressed areas disposed in a regular array with a period (pitch) not greater than W and a depth (peak-to-trough) in the range 10 to 1,000 nanometers. The medium comprises a substrate (1) and a regular array of zones of magneto-optic material (3) disposed at least over the peaks and troughs of the surface texture and conforming to the surface texture. In many embodiments, there is also a layer or a regular array of zones of an optically reflective material (2). In one embodiment, the texture is shallow, being generally in the range 10 to 120 nanometers. In a second embodiment, the depth of the texture is at least one tenth of the value of W. In any of the embodiments, there may be a dielectric layer over the top of the structure. The texture can take the form of a grating, or of crossed gratings, or be defined between an array of protuberances; structures with sinusoidal, square-wave (top-hat) or saw-tooth profile are advantageous.

摘要： A method of optical data storage which comprises encoding data into a code of order M, where M is an integer of (3) or greater, and writing the encoded data onto a receptive optical data storage medium using a laser system capable of generating (M-1) distinguishable pits in the surface of the receptive optical data storage medium. With such a method, the resultant data storage medium contains M different states, these being the lands together with the (M-1) pit states. The invention may be practiced using a plurality of lasers in order to generate the (M-1) pit states; alternatively, a single adjustable laser may be employed, e.g. one in which the intensity and/or wavelength and/or polarisation state of the laser beam may be modulated. A writing system for effecting optical recordings is also disclosed, this system including a semi-conductor laser under control of an electronic circuit arranged to ensure that the current flowing through the semi-conductor laser is always greater than the threshold current at which light is emitted.
