Abstract

1376936 Data storage SIEMENS AG 19 Nov 1971 [21 Dec 1970] 53757/71 Heading G4A [Also in Division G2] A holographic data storage system comprises a storage plate containing a plurality of subsidiary holograms each storing an elementary piece of information and means comprising one or more sources of coherent light of the same frequency, the means being arranged in operation to superimpose the elementary pieces of information from two or more subsidiary holograms during read-out to produce a composite piece of information. An array of holograms is read by a laser beam. The read-out detector has a storage action with a time constant greater than the time required to read-out all the elementary pieces of information forming a desired composite piece of information. Alternatively several laser beams may be provided to project several subsidiary holograms simultaneously on to a detector to provide the desired composite piece of information. The Specification states that analogue information may be stored, e.g. basic circuit elements which may be superimposed to form a desired circuit.
