Abstract

An apparatus and method are provided for recording information in the form of video signals on record members such as cards and reproducing selected portions of the information recorded as visually monitorable information on a viewing screen such as an electronic display or cathode ray tube. The information is recorded in the form of tracks of recordings which may be selectively scanned by a video transducer to generate electrical signals which may be used to modulate the reading means of an electronic display to present a visually monitorable or photographically reproducible image on said display.

Claims

1. A method of recording and reproducing video displayable information comprising the steps of:

recording a plurality of composite full-frame video signals along respective parallel tracks of a record card wherein each of said composite full-frame video signals containing picture signal elements and synchronizing signal elements applicable, when reproduced with said picture signal elements, for effecting the generation of images on a monitor screen of the information defined by said picture signal elements,

storing said record card with a plurality of similar record cards containing recordings of composite full-frame video signals of other displayable information, and

when it is desired to obtain selected recorded information and to monitor same, retrieving said card from storage and presenting same to a card reading apparatus,

controlling the operation of said card reading apparatus to selectively scan the track of said card presented thereto which track contains the full-frame video signal defining the information to be monitored,

generating on the output of said card reading apparatus the full-frame video signal reproduced in scanning the recording of the selected full-frame video signal and

presenting the reproduced full-frame video signal to a video monitor and using same to generate a viewable image representative of the selected recorded information.

2. A method in accordance with claim 1 wherein said card reading apparatus comprises a bank of reproduction transducers including at least one transducer located to scan each of said parallel tracks of a record card presented thereto, said method comprising selectively energizing at least one of said transducers while driving said card through said card reading apparatus to cause said selectively energized transducer to sense the recording provided along a selected track of the card and to reproduce information as electrical signals on its output which signals are representative of the recordings provided along the track scanned thereby.

3. A method in accordance with claim 2 wherein said plurality of record cards each contain plural record tracks extending parallel to the longitudinal axis of the card and said card reading apparatus is operable to drive each card longitudinally past said bank of transducers with each of said transducers being in scanning alignment with a respective record track of the card whereby all of said card tracks are simultaneously scanned by respective transducers of said bank.

4. A method in accordance with claim 1 which includes supporting the record card to be read in a cylindrical configuration during the reading operation and rotating said cylindrically configured card past a transducing means while energizing said transducing means in a manner to cause it to scan a selected recording area of the card and to generate signals representative of the information recorded along said selected area of said card.

5. A method in accordance with claim 1 which includes driving the card to be read in a direction which is at an angle to said track to be scanned, and scannably moving a transducing means while the card is in motion in a manner to effect scanning of the information on the track being scanned and the generation of said full frame video signal on the output of said transducing means.

6. A method of recording full frame video signals along a selected recording area of a record card comprising:

presenting a record card to a card recording means having a recording transducing means,

detecting the presence of said card at said card recording means and generating a control signal when said card is predeterminately aligned within said card recording means,

applying said control signal to control the operation of a means for generating a full frame video picture signal and

causing said card recording means to be modulated by said full frame video picture signal and to effect a recording representative of said full frame video picture signal along a selected recording area of said card.

7. A method in accordance with claim 6 wherein said means for generating said full frame video picture signal comprises a television camera, said method including triggering a control circuit for controlling said camera to execute a full frame scan of its field and to generate said full frame video picture signal on its output and pass same to modulate said card recording means to effect said recording along said selected area of said card.

8. A method in accordance with claim 6 wherein said card recording means includes a magnetic transducer which is operably aligned with a selected track of the card when the card is recorded on thereby and said selected track is provided with magnetic recording material to be recorded on by said transducer.
