Abstract: 1,086,472. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 6, 1965 [June 10, 1964], No. 19128/65. Heading G4A. [Also in Division H4] In an optical read-only store, aligned storage elements in which data is stored in the form of light-reflecting layers are interleaved with control devices energizable to rotate the plane of polarization of light passing therethrough by 45 degrees, data being read from a selected storage element by energizing the control devices adjacent the selected element and passing plane polarized light through all the storage elements, light coherently reflected from the layers in the selected element being thereby polarized at 90 degrees to the incident light and that reflected from other storage elements so that it can be separated out. The light from the selected storage element may be significant by its shape or be digital, and is sent to photodetectors or display or printing means. An adjustable filter is placed in the incident or reflected light to select data in sets of reflecting layers having a particular spacing.
