A method for storing a set of files on a multiple volume media set supports the ISO/IEC 13346 standard for optical media while minimizing swapping and temporary storage requirements when the multiple volume media set is used in an optical disk autochanger. The method allows the media set (e.g., optical disks) to be self-describing in accordance with the ISO/IEC 13346 standard. However, when the media set is on-line, the meta-data is separated from the data to optimize on-line performance. The method sequentializes the meta-data of the file set before writing it to the media set to achieve these advantages.

A method for sequentially writing non-sequentially formatted meta-data for a set of files on a multiple volume media set, wherein said method minimizes a number of media swaps necessary to read and write said metadata from and to said multiple volume media set, comprising the steps of: (a) determining an amount of space on said media set required to store an information control block table containing information control blocks for all data files and directories as well as any overflow sectors and logical links in the set of files; (b) reserving space, on the multiple volume media set, for said information control block table to be recorded in a first portion having a size sufficient to store said information control block table; (c) building a directory having an entry for each of its subdirectories and files, wherein each entry has an information control block address sequentially assigned to each of said subdirectories and said files; (d) writing said directory to a second portion of the multiple volume media set; (e) repeating steps (c)-(d) for every other directory file in said set of files, wherein said repeating step starts at a starting point and follows a preset order; (f) building an information control block for each of said data files and directories in the set of files, directories and subdirectories; and (g) writing each of said information control blocks built at step (f) into said information control block table at said information control block address assigned in step (c), wherein the number of media swaps necessary to read and write said metadata from and to said multiple volume media set is minimized.
