EIAJ Standards for ${1\over 2}$-in Videotape Recorders
Yoshio Sawaji
The following standard, promulgated by the Electronic Industries Association of Japan (EIAJ) is presented here for informational purposes. The contents of the paper deal with the specifications of a format for helical video tape recorders making use of ${1\over 2}$-in magnetic tape. The format is commonly referred to as EIAJ Type I. Equipment making use of this format is currently available in the United States, Canada, Japan and elsewhere but the English language version of the EIAJ standard has only recently become available. It is important to note that, although the contents of the EIAJ Type I format specifications are now under study by the Helical Recording Subcommittee of the SMPTE Video Tape Recording Committee, the publication here of the EIAJ document does not imply approval of its technical content by SMPTE or ANSI. Rather, it is hoped that publication will provide useful information to users of such recording equipment.—Frederick M. Remley, Jr., Chairman, SMPTE Helical Recording Subcommittee of the Videotape Committee.
