  • (a) storing the file contents of each file in a contents buffer comprising a segmented data buffer, and comprising the step of;

    (a1) storing the file contents received from a source media of a data file in the data buffer;

    (b) storing, separately from the contents buffer, the file location information for the at least two files in an information buffer comprising a segmented directory header buffer, a segmented header buffer and a segmented directory buffer, and comprising the steps of;

    (b1) producing a file directory entry from the file description information and storing the file directory entry in the directory buffer;

    (b2) producing a file header from the file description information and storing the file header in the header buffer; and

    (b3) producing a directory header from the file description information and storing the directory header in the directory header buffer; and

    (c) writing, to the storage media, a portion of the contents of the contents buffer when the contents buffer is a predetermined percentage full and separately writing a portion of the contents of the information buffer to the storage media, including the file location information of the at least two files, when the information buffer is the predetermined percentage full, and comprising the steps of;

    (c1) separately writing the contents of a full segment of the data, directory, header and directory header buffers to the random access storage media; and
