Profile: | The CEA is a scientific and technical research organisation specialised in nuclear, civil and defence activities, new energy technologies, and information and health systems. Its ability to relate fundamental research and valorisation in the industrial environment enables it to play a leading role in innovation. The CEA has nearly 15,000 employees in 10 sites throughout France. Located in Grenoble, the CEA’s LETI laboratory is a leading actor in European research and development of microelectronics and microtechnologies. It has 900 employees. With 160 patents filed per year, 30 start-up companies created or currently being created, 180 partners, and 350 contracts signed per year, it is one of the privileged partners of the industrial community. It was the instigator of the innovation project for micro and nanotechnologies (Minatec) and is also one of its main partners. The Optronics and Multimedia Laboratory is working on various storage technologies in seeking to develop media with a capacity as high as several hundreds of GB or even TB: • Holography allowing very high capacities to be reached by recording data through the volume of the medium and not just on its surface. • Near-field optics where the marks that are used to record the information have dimensions 5 to 8 times smaller than the wavelength of the light that is used for writing and reading. • Micropoint recording that uses a microscopic sized metallic point to record marks with dimensions of around 10 to 20 nanometres (a millionth of a millimetre) using an electric current. The laboratory has a set of models and codes enabling it to design these systems and the equipment needed to produce and test the storage media. In co-operation with THOMSON-DTB, we have developed nomad archiving solutions that use miniature (3 cm in diameter) and high capacity (5 Gb) disks. These are extremely competitive as the materials that are used have a non-linear behaviour during photon irradiance. Finally, at Leti, we are developing robust archiving solutions for the “100 Gb for a 100 years” concept using new inorganic materials and innovative formatting processes. |
