Dir

Based on the D1 format, DIR was fast enough for sonar, radar and other high-speed data archiving. Cassettes came in 8.7GB, 43GB and 96GB capacities. Once a standard in the U.S. government, DIR was gradually replaced by LTO and SAIT technologies. See DTF, LTO, AIT and magnetic tape.

Next to the 4mm DAT cassette, the 96GB DIR cassette was enormous.
