摘要： A method of forming an image and a radiation-sensitive medium suitable for carrying an image is disclosed. The medium comprises a substrate having a surface structure comprising grooves with a depth of 20 to 100 nanometers. At or close to the surface structure there is a layer of radiation-responsive material which is such that irradiation of selected parts of the structure with radiation of a predetermined polarization causes radiation to be absorbed at the irradiated parts of the surface so that corresponding areas of the radiation-responsive layer are affected in a way which makes such areas distinguishable from the remaining, non-irradiated areas of the radiation-responsive layer. An image and/or data may be stored in such a medium in analogue, digital or pictorial form, or in a combination of any two or all three of these forms. The invention also provides primary and secondary pre-formed data carrying media, the secondary media being replicated from the primary media. A primary pre-formed data carrying medium is formed by selectively irradiating a radiation-sensitive medium of the invention so as to form an image representative of a predetermined amount of data.

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： Apparatus for measuring displacement comprises a member, such as a reading head, which carries a stepped index diffraction grating (14) and is movable with respect to a reflective scale grating (16). The head also carries a source (10) and lens for directing light on to the index grating and then on to the scale grating for reflection to the index grating, with the resultant Moire bands detected by a photodetector (18) on the reading head. In order to determine the phase separation or offset, and to avoid high sensitivity thereof to the spacing between the gratings, the index grating (14) has a square-stepped profile resulting in graded, increasing thickness. Alternatively, a conventional index grating may be employed in conjunction with a stepped profile optical element interposed between the two gratings.

摘要： A position detector is provided for detecting the relative movement of first and second members which are mounted for relative movement along a measuring path. One of the members comprises a magnetic field generator for generating a magnetic field and the other member comprises first and second conductors which are inductively coupled to said magnetic field generator. The arrangement of the first and second conductors and the magnetic field generator is such that output signals are generated in a first and second receive circuits whose position varies with the relative movement between the two members. In addition to carrying information relating to the relative position between the two members, the signals induced in the receive circuits also comprise information defining the relative orientation of the two movable members, and by suitable processing of the received signals the relative orientation of the two members can also be determined. In a preferred form of the invention, the system operates to define the relative position and orientation of the two movable members in first and second directions from which the relative orientation of the two members in a plane containing the two directions can be determined. The signals induced in the receive circuits can also be processed to give an indication of the gap between the two circuits and to provide an indication of the full relative orientation of the two members.

摘要： This application discloses a method of recognizing and/or locating preselected categories of articles, which comprises applying to the articles a plurality of magnetic elements in predetermined associations (e.g. with predetermined numbers of magnetic elements and with predetermined spacings between said elements), whereby when the articles are caused to move relative to a predetermined interrogating magnetic field, each particular association of magnetic elements gives rise to a magnetic signature whereby the article or category of article carrying each of the predetermined associations can be recognized and/or located. A series of tags or markers for use in such a method, as well as a system for determining the location and/or identity of an article within an article conveying network, are also disclosed. Typically, one of such a series of tags will have a plurality of magnetic elements (2, 3, 4, 5, 6, 7, 8, 9, 10) whose individual magnetic characteristics, and whose number, shape, location and orientation on a substrate, determine the individual character of the magnetic response of the tag. By varying one or more of these parameters, a large family of magnetically individually recognizable tags can be generated.

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 method for manufacturing a 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 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 pattern is further coated with a thin film of a high-opacity material, e.g. gold, the thickness of the overcoating preferably being such as to give no more than 10% transmission of incident radiation.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 prerecorded in part or in entirety.
