PCT No. PCT/SE93/01126 Sec. 371 Date Aug. 12, 1994 Sec. 102(e) Date Aug. 12, 1994 PCT Filed Feb. 17, 1993 PCT Pub. No. WO93/16476 PCT Pub. Date Aug. 19, 1993.The invention relates to a read-write optical memory comprising a plurality of juxtaposed memory cells (11), each receiving a respective light beam (3). Each memory cell contains a storage medium (10), which includes a storage element (23) having stable optical states. The storage element (23) is divided into a number of memory points, and the optical state in a given memory point can be both changed and read by means of a light beam (3) directed towards the memory point. The memory can be implemented entirely without any movable mechanical parts and has a very short read-write time and an exceptionally high storage capacity. Parallel writing and reading of multibit words is possible. |
