Abstract
Abstract A system is described for storing and retrieving information stored on two types of media, such as microfilm and magnetizable material, the latter being more readily altered to revise and add current information. Means are provided for displaying the two records simultaneously, and selection of one record is sufficient to cause selection of a corresponding record stored on the other type of media through the utilization of addressing means which automatically access the corresponding record on one media upon selection of a record on the other media.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
Information storage and retrieval equipment comprising: a first information store containing a plurality of discrete first records, said first records being on an optically readable first media not readily adapted to selective erasure and reuse: a second information store containing a plurality of discrete second records, said second records being on an electronically readable second media readily adapted to selective erasure and reuse; first record selection means for selection of a desired one of said first records; optical projection means for visually displaying a representation of said selected first record on a viewing surface; coding means associated with said first selection means to generate a unique code signal corresponding to said selected first record; record selection means associated with said second information store to automatically select one of said second records in response to said code signal; and cathode-ray tube means to visually display a representation corresponding to said second record on said viewing surface in juxtaposition to said visual display of said representation of said first record.
Claim 2
Dependent Claim
168 words
Information storage and retrieval equipment comprising: a first information store containing a plurality of discrete first records, said first records being on an optically readable first media not readily adapted to selective erasure and reuse: a second information store containing a plurality of discrete second records, said second records being on an electronically readable second media readily adapted to selective erasure and reuse; first record selection means for selection of a desired one of said first records; optical projection means for visually displaying a representation of said selected first record on a viewing surface; coding means associated with said first selection means to generate a unique code signal corresponding to said selected first record; record selection means associated with said second information store to automatically select one of said second records in response to said code signal; and cathode-ray tube means to visually display a representation corresponding to said second record on said viewing surface in juxtaposition to said visual display of said representation of said first record.
Claim 3
Dependent Claim
168 words
Information storage and retrieval equipment according to claim 1 wherein: said first information store comprises microfilm on which said plurality of discrete first records are recorded as a plurality of microfilm frames on a plurality of microfilm strips; said first record selectIon means comprises means for selecting a strip of microfilm, means for selecting a frame of the microfilm strip for display as the frames are moved in sequence past the selecting means, and means for individually selecting a discrete record on a displayed frame; and said coding means comprises a plurality of switches operable in predetermined combinations in response to the selection of a particular strip, means for counting the microfilm frames sequentially passing said frame selection means to enumerate the frame selected by said frame selecting means, and means for indicating the position of said individual record selecting means relative to the displayed frame, whereby these three sources of information identify the selected individual record and provide said unique code for selecting the associated second record.
Claim 4
Dependent Claim
47 words
Information storage and retrieval equipment according to claim 2 wherein said second information store comprises magnetic data storage means adapted to cooperate with electronic data processing and retrieval means responsive to said code signal to retrieve and display the second record corresponding to the selected first record.
Claim 5
Dependent Claim
25 words
Information storage and retrieval equipment according to claim 1 further including manual data entry means for altering selected records among said readily alterable second records.
Claim 6
Dependent Claim
45 words
Information storage and retrieval equipment according to claim 1 wherein said viewing surface is the screen of said cathode-ray tube which has a transparent window therein, and said optical projection means is positioned to project a representation of said first record onto the tube screen.
