20110137064 | METHACRYLATE-BOUND PHOTOISOMERIZABLE CHROMOPHORE, METHODS FOR ITS SYNTHESIS - The invention discloses novel dicyanostilbene derivatives bound to a methacrylic moiety that can serve as an active chromophore in a 3-dimensional optical memory, processes for its synthesis and its intermediates. | 06-09-2011 |
20100290332 | OPTICAL DATA CARRIER WITH REFERENCE LAYER - An optical information carrier is presented. The information carrier comprises at least one active layer for recording/reading data in/from as a result of one- or multi-photon interaction; and at least one reference layer structure associated with said at least one active layer. The reference layer structure comprises at least one dielectric material and is different from that of the active layer in its optical properties with respect to one- or multi-photon interaction. Detection of light returned from the reference layer structure allows to control a process of focusing an optical beam onto an addressed recording plane in the active layer during at least one of the recording and reading processes. | 11-18-2010 |
20100002555 | CONTROL SIGNAL FOR THREE DIMENSIONAL OPTICAL DATA STORAGE - A method is presented for use in determining a degree of quality of a multi-layer optical data carrier in its at least partially recorded state. Predetermined first data is provided being indicative of a qualified, at least partially recorded multi-layer optical data carrier. This data corresponds to an optical response obtainable from a specific data carrier under predetermined conditions of an optical scan of the rotating data carrier. A data carrier being qualified is scanned by at least one optical beam under said predetermined conditions of the scan, and a first control signal from the data carrier is detected and data indicative of the detected control signal is generated. The so generated data is processed to determine a relation with said predetermined data. The determined relation is used for determining a degree of quality of said scanned data carrier. | 01-07-2010 |
20090310473 | OPTICAL DATA CARRIER AND METHOD FOR READING/RECORDING DATA THEREIN - An optical data carrier is presented. The data carrier comprises at least one recording layer, at least one non-recording layer, and at least one reflective interface. The recording layer is made of a material having a fluorescent property variable on occurrence of multi-photon absorption resulted from an optical beam, and has a thickness for recording therein data in the form of a three-dimensional pattern of spaced-apart recording regions arranged in a plurality of recording planes. The at least one non-recording layer interfaces with the recording layer on, respectively, at least one of upper and lower surfaces of the recording layer The non-recording layer has a fluorescent property different from that of the recording layer, and has a predetermined thickness selected to be equal or larger than a focal depth of an optical system producing the optical beam incidence onto the data carrier. The at least one reflective interface comprises at least one reference layer having a reflecting property. The at least reflective layer is formed on the other surface of the at least one non-recording layer, respectively, such that the non-recording layer in sandwiched between the reference layer and the recording layer. | 12-17-2009 |
20090310464 | THREE-DIMENSIONAL OPTICAL INFORMATION CARRIER - An optical data carrier is presented comprising first and second recordable media located in at least one first portion and at least one second portion of the data carrier, respectively. These first and second recordable media differ from each other in a storage capacity and a data recording rate. | 12-17-2009 |
20090290464 | Data Protection in an Optical Data Carrier - An optical data carrier is presented being configured to provide protection for data recordable therein from environmental effects. The optical data carrier comprises recordable media having an outer surface and an inner data volume in which data is to be recorded, said data volume being spaced from said outer surface a certain minimal distance D, a region of the recordable media surrounding the data volume providing at least optical protection for said data volume. | 11-26-2009 |
