Abstract
Abstract An optical floppy disc constructed of microfilm, thermoplastic or paper and bears digital and/or graphic information. Digital information may be stored in radial lines each of which comprises the digital information to be retrieved and line addresses at the end of a line or dispersed within a line. Digital information may also be stored in a plurality of coaxial circular tracks and be retrieved by addressing the track and portion of the track containing the desired information. Information retrieval systems, both continuously rotating and start-stop systems are provided for reading the various types of discs. Of particular importance is the use of a disc as an easily up-dateable catalog.
