7、in Switzerland ii 0 ISO/IEC ISO/IEC 9983:1995 (E) 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 developm
8、ent 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 inf
9、ormation technology, IS0 and IEC have established a joint technical committee ISOLIEC 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
10、 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, Information technology, in parallel with its approva
11、l by national bodies of IS0 and IEC. This second edition cancels and replaces the first edition (ISOLIEC 9983:1989), which has been technically revised. Annex A of this International Standard is for information only. . . . 111 ISOiIEC 9983:1995 (E) 0 ISO/IEC Introduction Since the beginning of their
12、 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 (35 in). It can be foreseen that in not too distant a future further smaller sizes may be considered. Some of th
13、ese cartridges, whilst having the same size, do not have the same magnetic characteristics and, therefore, should be used only with the physical recording density and the number of tracks for which they have been designed. In practice, however, they are offered commercially to end users in packages
14、bearing indications (e.g. lD, DD, I-ID, 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
15、 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
16、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 wo
17、uld 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. iv INTERNATIONAL ST
