Apparatus for recording sound on microfiche

Claim 1

An apparatus for recording sound patterns consisting of: a. means for producing a beam of coherent electromagnetic radiation; b. means producing a signal to be recorded; c. modulating means receiving said beam of coherent electromagnetic radiation and said signal to be recorded and creating an optical image; d. extinction control means operatively connected to said modulating means to prevent amplitude modulation drift, wherein the improvement comprises: 1. a member having a slit therein for passing said modulated beam of coherent electromagnetic radiation therethrough; 2. a plurality of optic fibers arranged with their first ends in a closed curvilinear line and their second ends in an open line pattern; 3. optical means mounted adjacent said slit for sequentially projecting said beam upon each of said first fiber optic ends; 4. an elongatd recording member movably located adjacent the second ends of said fibers for receiving and retaining said image thereon; and 5. means moving said recording member during the recording process. e. said optical means including a mirror mounted for rotation for receiving said modulated beam and sequentially reflecting said beam upon each of the first ends of said optic fibers; f. said optical means including a rotatable shaft connected to said mirror; g. a lens mounted on said shaft for rotation therewith for receiving said reflected beam from said mirror, and reducing, focusing and projecting said beam sequentially upon the first ends of said optic fibers; h. said first ends of said optic fibers being arranged in substantially a circle and the ends of said optic fibers having planar faces in a plane angularly related to the longitudinal axis of said optic fibers; i. said plane of said mirror being angularly related to the longitudinal axis of said shaft; and j. said means for moving said recording member being operatively connected to said shaft of said optical means for synchronizing the movements of said mirror, lens and recording member.
