20090116367 | FERROELECTRIC RECORD CARRIER, ITS METHOD OF MANUFACTURE AND MICRO-TIP RECORDING SYSTEM INCORPORATING SAME - The present invention relates to a data record carrier of the type with ferroelectric memory layer, its method of manufacture and a micro-tip recording system incorporating same. The invention applies in particular to computer-based or multimedia applications requiring high memory capacities. A record carrier according to the invention comprises a substrate, a counter-electrode deposited on the substrate and intended to cooperate with an electrode of a data reading and/or writing device, and at least one ferroelectric memory layer which is able to store these data and which exhibits a first face in close contact with said counter-electrode. According to the invention, the counter-electrode is made of a substance comprising a carbonaceous material chosen from the group consisting of carbon in the form of graphite or amorphous diamond, the carbides of a metallic or non-metallic element with the exclusion of ionic carbides, and their mixtures. | 05-07-2009 |

20090173929 | DATA MEMORY, WRITABLE AND READABLE BY MICROTIPS, WHICH HAS A WELL STRUCTURE, AND MANUFACTURING METHOD - The invention relates to data storage memories, that can be written and read by using at least one write or read microtip which comes near to a point zone to be written or to be read on the surface of a substrate, either in order to change the physical state of this zone, when writing or erasing, or in order to determine the physical state of the zone, when reading, the data stored in the zone being defined by the physical state of the zone. The surface of the substrate is subdivided into a set of individual islands ( | 07-09-2009 |
20090175153 | Electrical-Effect Data Recording Medium that Includes a Localized Electrical Conduction Layer - An electrical-effect data recording medium is preferably formed by a successive stacking of a protective layer, a localized electrical conduction layer, a recording layer, a thin layer forming an electrode and a substrate. The localized electrical conduction layer is formed by a low electrical conductivity material, in which inclusions having a higher electrical conductivity than that of the material are dispersed. The inclusions can be oblong or spherical in shape and the material presents a non-linear electrical conduction. | 07-09-2009 |
