This International Standard specifies requirements for the file structure and the labelling of flexible disk cartridges for the interchange of information between users of different information processing systems.<\/p>\n

This International Standard specifies<\/p>\n

    \n
  1. recorded labels to identify files, file sections, and volumes of flexible disk cartridges;<\/li>\n
  2. basic characteristics of the blocks containing the records constituting the file;<\/li>\n
  3. the file structure.<\/li>\n<\/ol>\n

    This International Standard specifies three nested levels of interchange so that<\/p>\n

      \n
    1. at the first level, called BASIC INTERCHANGE (BI), it is possible to interchange data by using a minimum set of the facilities provided;<\/li>\n
    2. at the second level, called EXTENDED INTERCHANGE LEVEL 1 (E1), it is possible to interchange data using the minimum set together with blocks having a length greater than that of the physical records and with blocked fixed-length records;<\/li>\n
    3. at the third level, called EXTENDED INTERCHANGE LEVEL 2 (E2), it is possible to interchange data using the facilities of levels BI and E1 together with variable-length records and segmented records.<\/li>\n<\/ol>\n

      Annex A describes examples but does not form part of this standard.<\/p>\n

      Annex B gives disk parameter values derived from flexible disk data interchange standards, but does not form part of this standard.<\/p>\n
