If the medium is magnetic tape, it should preferably be 1/2" industry standard 9 track (unlabelled and with the ASCII character set). The eighth bit (i.e., most significant bit) shall be set to zero when transferring 7 bit data. The physical block size shall be preferably 1024 characters but may be any clearly designated integer multiple of this size and preferably use the ANSI X3.27–1987 "D" (unspanned variable length records) format. The reel size should preferably be 7".
Tapes recorded at either 800 bpi, NRZI (ANSI X3.22–1990) or 1600 or 6250 bpi phase-encoded (ANSI X3.39–1992) are recommended for current systems.
