MIL-HDBK-9660B, DEPARTMENT OF DEFENSE HANDBOOK: DOD PRODUCED CD-ROM PRODUCTS (1 SEP 1997)., This handbook is approved for use by all Departments and Agencies of the Department of Defense (DOD). 2. This handbook is for guidance only. This handbook cannot be cited as a requirement. If it is, the contractor does not have to comply. 3. The production and use of Compact Disc-Read Only Memory (CD-ROM) have significantly different considerations than of paper products. This handbook serves to provide guidance to Department of Defense agencies on the use of Compact Disc (CD) technology as the recommended method for physical distribution of information within DOD. This document is the basis for addressing current/future CD-ROM issues/concerns and will be revised as guidelines and new standards mature. 4. The International Organization for Standardization (ISO) CD-ROM standards, ISO 9660 and ISO 10149, have been widely accepted for sharing large amounts of information across all computing platforms. ISO 9660 standardizes how CD-ROM sectors are organized into logical records, then grouped into files, directories and volumes. ISO 10149 addresses the physical format of CD-ROM. With the acceptance of the two ISO standards, the use of CD-ROM to store and disseminate information has become a reality, and has been implemented throughout DOD as a means of reducing paper/microform/magnetic media distribution and attendant costs. However, the producers of CD-ROM determine what user interfaces, application platform support, and utility of the information are provided. Ultimately, end users must deal with CD-ROM products containing different access/retrieval capabilities. Standards and guidelines lighten the burden on the end user, standardize production procedures, and streamline migration from paper/microform/magnetic media products to CD-ROM media products. 5. All DOD components/activities should evaluate the use of ISO 9660 compliant CD-ROM for the distribution of information. 6. All DOD components/activities producing CD-ROM products for use within DOD should adhere to the standards and general guidelines provided in this handbook. 7. Handbook objectives: a. Encourage a common migration path to CD-ROM. b. Compile adopted standards for the use of CD-ROM. c. Provide general guidance to CD-ROM producers/users. d. Establish a DOD forum for discussions of CD-ROM issues/standards, their use by DOD publishers, their impact on DOD end users, and their impact/use in the CD-ROM industry as a whole. e. Provide a central DOD library/catalog of CD-ROM titles and their contents where applicable to DOD components/activities. 8. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: DISA/JIEO Center for Standards, 10701 Parkridge Boulevard, ATTN: Mr. James Barnette, Reston, VA 20191-4357, by using the self- addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document, or by letter.【英文标准名称】:Hydraulicfluidpower-Four-portdirectionalcontrolvalves-Mountingsurfaces.
