12、of American National Standard X3 116-1986 ) This standard presents the technique for recording ASCII in accordance with American National Standard for Information Systems - Coded Character Sets - 7-Bit American National Standard Code for Information Interchange (7-Bit ASCII), ANSI X3.4-1986, or othe

13、r standard codes, on a 0.250 inch (6.30 mm) mag- netic tape cartridge at 6400 bpi (252 bpmm) using inverted modified frequency modulation recording techniques. It is one of a series of standards implementing ASCII in media. Related standards define more fully the physical and magnetic properties of

14、the magnetic tape cartridge and specify a record format and labels. The X3B5 Technical Committee on Digital Magnetic Tape, which developed this standard, consists of a group of experienced and qualified specialists in the record- ing of digital information on magnetic tape. In the development of thi

15、s standard, careful consideration was given to current practices, existing equipment and sup- plies, and the broadest possible acceptance to provide a basis for future improve- ment in the use of the medium. This standard was approved as an American National Standard by ANSI on June 30, 1986. Sugges

16、tions for improvement of this standard will be welcome. They should be sent to the Computer and Business Equipment Manufacturers Association, 311 First Street, NW, Washington, DC 20011. This standard was processed and approved for submittal to ANSI by the Accredit- ed Standards Committee on Informat

17、ion Processing Systems, X3. Committee approval of this standard does not necessarily imply that all committee members voted for its approval. At the time it approved this standard, the X3 Committee had the following members: Edward Lohse, Chair Richard Gibson, Vice-Chair Catherine A. Kachurik, Admin
