Image filing apparatus and method for storing image data and directory information
First Claim
1. Digital-data write/read apparatus comprising:
- a disc for writing thereto/reading therefrom data, with the data stored in said disc being arranged in such a manner that said data defines a plurality of sectors/clusters of data, the recording area of said disc comprising a directory information region for storing directory information therein and an actual data region for storing data files therein, the regions being positionally and functionally separated from one another, said directory information comprising file name records, each of which comprises a file name, file production data/time, information for pointing the position of the file in said actual-data region, the file size and identification information;
identification information inputting means for inputting the identification information; and
data processing means for inputting/outputting and managing the data constituting the data files, said means comprising a microprocessor, first information storage means for storing therein a first type of information obtained from said disc, second information storage means for storing therein a second type of information produced from said first type of information and instruction means for receiving instructions from an operator and then giving said instructions to said microprocessor, wherein said second type of information comprises an identification-information retrieval table information using said identification information which comprises matters different from matters indicating positions on said disc.

Abstract
An addition unit adds information for managing a plurality of image-data files to directory information packets. A managing unit utilizes the added information for managing the plurality of image-data files. A retrieving unit retrieves, in accordance with an input retrieving information, a desired image-data file from among the plurality of image-data files recorded on a recording medium. An image-data input and output interfacing unit interfaces for input and output of image-data files. A recording-medium interfacing unit interfaces for information input and output by means of the recording medium. An output video-signal producing unit produces a video signal for output, the producing being effected by converting the retrieved image-data file into a corresponding analog video signal and using the analog video signal as the video signal for output. A signal combining unit combines the video signal for output, the combining being executed with a retrieval video signal, the video signal for output having been output from the output video-signal producing unit, and the retrieval video signal having been obtained by converting the input retrieving information into a corresponding analog video signal then used as the retrieval video signal. A microcomputer carries out the above functions.
