| The memory disc (1) comprises at least one substrate base disc (2) and a screening disc (7), arranged at a distance from the latter. Both discs are produced from plastic by means of a mould (10) in an injection-moulding or transfer-moulding process. The discs are connected to each other, at least in the outer peripheral region, by being welded together by means of moulded-on webs. The substrate base disc (2) has an information layer (4) and, in the region thereof, a microstructure, which is taken over from a mould (10) which is provided at least in the outer region with depressions (16) for forming the webs (5). The depressions (16) in the mould, or in a negative electroplate used for producing the mould, are created by means of high-energy radiation focused to a certain depth below the surface of the mould or of the electroplate, by melting and vaporising the material of the mould or electroplate. <IMAGE> | ||||||

| There is disclosed an organic optical recording medium with high data storage density, high data rates and long data archival capabilities, useful as a medium for recording a variety of information or pictures.In a preferred embodiment, the optical recording medium according to the present invention comprises a substrate, a reflective layer, a charge-generating layer containing at least one charge-generating material, a charge-transferring layer containing at least one charge-transferring material, a recording layer containing at least one electric field-discoloring element, a plurality of spacers, an air layer and a protective layer.A laser beam is absorbed to the charge-generating material contained in the charge-generating layer, to generate charges, which are subsequently transferred to the surface of the recording layer by the charge-transferring layer.With the influence of the charge generated, the illuminated area having the charges puts on a color different from that in the other areas. In readout of the recorded information, a laser beam of lesser intensity is scanned across the recorded medium. The erasure of the recorded data is carried out by discharging the charges generated on the surface of the recording layer. As a result, the erasure in the optical recording medium is performed much simpler. | ||||||

| Disclosed is an optical disk used as a recording medium of the type described as an air-sandwiched structure including two disk-shaped substrates, which are secured to each other by way of an inner and outer plastic spacer. Together, the two substrates and the inner and outer spacer define a closed inner space, and at least one inner surface of one of the two substrates is provided with a light-sensitive recording layer. Typically, such a recording layer is sensitive to high energy light such as that from a laser beam. Each of the disk-shaped substrates includes a central hole of equal size and shape, wherein the inner spacer is ring-shaped and is positioned with its central opening coaxial with the holes in the substrates. The improvement resides in that the inside diameter of the central hole of the inner spacer is larger than the diameter of the holes of the substrates, and in that a recessed seat is provided by recessed portions formed on both substrates adjacent to and around the holes of each substrate, for precisely fitting and aligning the inner spacer to both disk-shaped substrates. Such a structure ensures accurate positioning of the optical disk on a drive spindle without interference of excess adhesive used in securing the inner spacer to the substrates, as well as to ensure that the recording medium can be rotated with high precision. | ||||||

| An optical information recording disk is formed by a pair of disk-like substrates with an inner and an outer annular spacer member disposed therebetween. The inner spacer member supports an inner circumferential portion of each of the disk-like substrates, and the outer spacer member supports an outer circumferential portion of each of the disk-like substrates. The spacer members and substrates thus define an interior space. The spacer members and substrates are fixed together by means of a thermosetting adhesive agent. A notched portion is formed in at least one of the space members so as to communicate the interior of the disk with the ambient atmosphere. Thus, during heating of the disk for purposes of joining the substrates and spacers by hardening the adhesive agent, air in the interior space in the disk can escape through the notched portion. After heating, the notched portion is filled with a sealing member such as a solid member or another adhesive agent. | ||||||

| In the optical memory device of this invention, an annular information recording area is formed on one surface of a disc-shaped subplate which is rotatable about a center hole. Information is recorded on, or read from, the circular or spiral track of the information recording area, the track being centered on the center hole. On the same surface of the subplate is formed a position signal area of the same material as that of the information recording area, but at a different position from the information recording area. As the device is rotated, the time when the position signal area passes a given point may be detected and used as a reference, so that the location within the track of recording or reproducing information can be determined. | ||||||
