摘要： An optical data storage system utilizes optical fibers for transfer of information to and from storage media. The storage media comprise magneto-optical storage disks. The optical fibers are low-birefringence optical fibers. As compared with conventional approaches, a polarization state conveyed by the optical fiber is accurately reproduced with reduced noise. Various noise reduction techniques are provided by substantially decreasing or eliminating spurious reflections (or the effects thereof) at end faces and of an optical fiber. In particular, various techniques, such as index matching, a cover slip method, laser modulation, or angle polishing, may be used to eliminate spurious reflections (or the effects thereof) at the front end face of the optical fiber. Various techniques, such as angle cleaving, index matching, or multi-mode fiber splicing, may be used to eliminate spurious reflections (or the effects thereof) at the back end face of the optical fiber.

摘要： A magnetic disk has a layered configuration comprising a recordable layer (110) and a reflective layer (112). Laser-stimulated recording takes place by a magnetic head (102) that obstructs the laser beam for a minor portion. The converging laser beam traverses the recording layer and gets reflected at the reflective layer, whereupon it reaches its focus in the recordable layer. The head gets only a fraction of the radiation. This enables to keep the head's temperature well within control.

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. The medium comprises a substrate; a layer or a plurality of zones of magneto-optic material; and a layer or a plurality of zones of an optically reflective material (which may or may not be the same as and/or constituted by the magneto-optic material). The magneto-optic material is disposed so as to be accessible to incident optical radiation. In one embodiment, the texture is shallow, being generally in the range 10 to 50 nanometers. In a second embodiment, the depth of the texture is at least one tenth of the value of W. 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 forming an image and a radiation-sensitive medium suitable for carrying an image. 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 polarisation 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.
