Abstract: Storage of information is performed by interference effects in depth in an optically accessible information storage unit. The storage unit is divisible into a plurality of individual information storage areas permitting the recording of the information in the form of various light and no light conditions. Plural light scattering layers are formed in depth in the unit corresponding to the information stored in that area. Read out is performed by applying light to the unit. The scattering layers act on the applied light in accordance with the information stored to provide indications for detection of the stored information.

Abstract: 1,026,317. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 28, 1964 [May 1, 1963], No. 17489/64. Heading H3B. [Also in Divisions G2 and G5] Information is recorded on a thermoplastic surface by using a laser beam to heat the surface and cause local deformations in the surface. In Fig. 1, the beam from a laser 16 is split by a half-silvered mirror 20 and part of the beam is focused by a lens 26 on to the tape record 10 to melt its surface and thereby erase any information previously recorded. The other part of the beam is reflected by a mirror 28 through a variable focus lens 34 and a fixed focus lens 36 on to the tape which has previously been electrically charged by a unit 30. The lens 34 is adapted to focus or defocus the beam under the control of an information source 37, and when the beam is focused the record is heated sufficiently to cause local deformation of the surface under the influence of the electrostatic charge and surface tension. The laser 16 may be pulsed or continuous wave and may use calcium fluoride doped with divalent dysprosium, calcium tungstate doped with trivalent neodymium, ruby, or a gas such as helium, neon, argon, krypton or xenon, or a semi-conductor gallium arsenide diode.

Abstract: An optical read-only memory system for reading binary information from a film with transparent locations indicating bits. A plurality of lens systems are provided to successively divide the binary information from the film into smaller and more easily handled units of information. The system is adapted to be used also as an associative memory unit. Frequency modulation systems are provided for use of the system as a parallel operated associative memory. Frequency modulation is also used to reduce the number of light sources and photosensitive elements required.
