F6473K Magnetic Tape Unit

The F6473K, which began shipping in July 1993, was Fujitsu’s high-performance magnetic tape unit that used IBM 3490-format tape media. Fujitsu already had the F6470 magnetic tape unit (which started shipping in September 1987) that worked with IBM 3480-format tape media and the F6473A (which started shipping in March 1991) that could be expanded to house up to four drives. The F6473K, however, increased the storage capacity per tape fourfold to address needs for more data by utilizing double-length tape and a 36-track recording format.
