This International Standard specifies the mechanical, physical and magnetic characteristics of a lubricated magnetic disk of 210 mm (8.3 in) outer diameter and 100 mm (3.9 in) inner diameter intended for mounting in data storage devices. The International Standard defines the requirements for a disk to give satisfactory performance at 158 368 flux transitions per track. When used at other densities, equivalent performance may require changes to the mechanical, magnetic and electrical criteria. NOTE — The original design of the subject of this International Standard was made using the Imperial measurement system. Some later developments, however, have been made using SI units. In the process of conversion into the alternative system, values may have been rounded. Therefore, the two sets of figures are consistent with, but not exactly equal to, each other. Either set may be used, but the two shall be neither mixed nor reconverted.

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. This International Standard specifies a) recorded labels to identify files, file sections, and volumes of flexible disk cartridges; b) basic characteristics of the blocks containing the records constituting the file; c) the file structure. This International Standard specifies three nested levels of interchange so that a) at the first level, called BASIC INTERCHANGE (BI), it is possible to interchange data by using a minimum set of the facilities provided; b) 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 fixedlength records; c) at the third level, called EXTENDED INTERCHANGE LEVEL 2 (E2), it is possible to interchange data using the facilities of levels Bl and E1 together with variable-length records and segmented records. Annex A describes examples but does not form part of this standard. Annex B gives disk parameter values derived from flexible disk data interchange standards, but does not form part of this standard.

This International Standard specifies the mechanical, physical and magnetic characteristics of a lubricated magnetic disk of 130 mm (5.12 in) outer diameter and 40 mm (1.57 in) inner diameter intended for mounting in data storage devices. This International Standard defines the requirements for a disk to give satisfactory performance at 83 332 flux transitions per track. When used at other densities, equivalent performance may require changes to the mechanical, magnetic and electrical criteria. NOTE — The original design of the subject of this International Standard was made using the Imperial measurement system. Some later developments, however, have been made using SI units. In the process of conversion into the alternative system, values may have been rounded. Therefore, the two sets of figures are consistent with, but not exactly equal to, each other. Either set may be used, but the two should neither be mixed nor reconverted.

Abstract Cancels and replaces the first edition (1987). Specifies the volume and file structure of disk cartridges for the interchange of information between users of information processing systems. Also specifies an optional record structure. Applicable to various types of disk cartidges. Specifies the location of files of information on an FDC and a set of recorded descriptors. Specifies requirements for the processes which are provided within information processing systems to enable information to be interchanged between different system, utilizing recorded FDSc as the medium of interchange. Provides a method for the allocation of space that is independent of the number of files which are recorded on the volume. Does not specify the content and the organization of the files.
