1. In a bank check document handling system for capturing image and information data of negotiated bank checks for bank record processing and which system is managed by a host computer, a storage/retrieval module subsystem for storing said image and information data for retrieval and conveyance to any one of a plurality of image work stations and printers for conversion to human readable format, said storage/retrieval module subsystem comprising:

  • (a) means for receiving digitized optical signals containing bank check document image packets having (i) image data and (ii) sequential non-image information data related to said image data;

    (b) means for converting said digitized optical signals to digitized electrical signals forming said bank check document image packets;

    (c) storage operation means for storing, in real time, said bank check document image packets on identified areas of magnetic disk units via a file management system which includes;

    (c1) first storage file means for storing non-image bank check document data as a plurality of sequential files made up of a sequence of bytes of data;

    (c2) second storage file means for storing, in real time, said bank check document image packets in a structured file system made of a plurality of records where each record has a key field with an index identifying each record;

    (d) means for retrieving, in real time, a selected bank check document image packet while simultaneous and concurrent storing operations of bank check document image packets are taking place, said means for retrieving including;

    (d1) means for selecting said first storage file means or said second storage file means to effectuate retrieval of either or both non-image information and/or a selected bank check document image packet for transmission to a requesting work station or printer;

    (e) means for transmitting retrieved bank check document image packets to a work station or printer for display;

    (f) means for communicating with a host computer to receive operational instructions and to transmit retrieved sequential non-image information for use by said host computer.
