Abstract

Storage and retrieval of up to 20-30 x l0~ different characters is achievable by the system shown, Characters arranged in a spiral format and timing marks arranged in a circular format are recorded on a transparent material in the form of disc 2 by means of microphotographic techniques, The retrieval optics are mounted on a rotating terret and include a prism 3 and a reflector 4 mounted on one side of disc 2 and a reflector 5 and a prism 6 mounted on the other side of disc 2, The disc 2 is rotated at a high speed and the retrieving optics are rotated at a comparatively low speed such that when a desired character is in proper alignment with the re- trieval optics light from a flash lamp or modulated light source is projected through one half of the retrieval optics, through the desired character, through the other half of the retrieval optics and through a projection lens 7 to an image plane.

Storage and retrieval of up to 20-30 x l0~ different
characters is achievable by the system shown, Characters
arranged in a spiral format and timing marks arranged in
a circular format are recorded on a transparent material
in the form of disc 2 by means of microphotographic
techniques, The retrieval optics are mounted on a
rotating terret and include a prism 3 and a reflector
4 mounted on one side of disc 2 and a reflector 5 and
a prism 6 mounted on the other side of disc 2, The disc
2 is rotated at a high speed and the retrieving optics
are rotated at a comparatively low speed such that when
a desired character is in proper alignment with the re-
trieval optics light from a flash lamp or modulated
light source is projected through one half of the
retrieval optics, through the desired character, through
the other half of the retrieval optics and through a
projection lens 7 to an image plane.
