Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrical Commission) form the
specialized system for world-wide standardization. National Bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal with
particular fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0
and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint technical committee ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an
International Standard requires approval by at least 75% of the national bodies casting a vote.
International Standard ISO/IEC 9983 was prepared by the European Computer Manufacturers Association (as Standard
ECMA-124) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1,
1~$~mzatic~~ technology, in parallel with its approval by national bodies of IS0 and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 9983:1989), which has been technically revised.
Annex A of this International Standard is for information only.

Introduction
Since the beginning of their activity in the field of standardization of flexible disk cartridges IS0 has issued standards for such
cartridges of three different sizes, viz. 200 mm (8 in), 130 mm (5,25 in) and 90 mm (3,5 in). It can be foreseen that in not too
distant a future further smaller sizes may be considered.
Some of these cartridges, whilst having the same size , do not have the same magnetic characteristics and, therefore, should be
used only with the physical recording densi ty and the number of tracks for which they have been designed.
In practice, however, they are offered commercially to end users in packages bearing indications (e.g. lD, DD, HD, etc.)
which are clear for those skilled in the art but quite obscure to the average buyer. As a consequence it was necessary to arrive
at a consensus on type designation to be used nationally and internationally. Investigations have shown that manufacturers of
flexible disk cartridges are willing to print the proposed designation in addition to the presently used identifiers which would
remain during a transition period. The proposed designation is explicit in that it specifies not only a type, but also minimum
information indicating the main parameters as well.
In the interests of users it is desirable that the scheme described be implemented now and as a whole. However, as the
suppliers of flexible disk cartridges, drives and systems have already developed their own designations for cartridges, and their
own procedures for marking packages, it would be expensive to implement the whole scheme immediately. It is expected that
suppliers will introduce the specified marking of cartridges and packages, and the references in manuals, as soon as the re-
ordering of cases, packaging and printing makes this economically possible.

Information technology - Designation of unrecorded flexible disk cartridges
1 Scope
This International Standard specifies an identifier to appear on each flexible disk cartridge (FDC) and the minimum
information to appear on packages of unrecorded flexible disk cartridges.
The information according to this International Standard shall appear on cartridges and on packages of unrecorded flexible
disk cartridges available to end users. Drives for FDCs should bear the indication of the Type(s) of FDC they can handle.
Manuals for drives and systems should also include this information.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International
Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to
agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent
editions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid standards.
