(
Quarter
Inch
Cartridge) A magnetic tape technology introduced in the early 1980s that was used for backup. It was the only popular magnetic tape format for personal computers. The "quarter inch" name came from the original tape width; however, subsequent Travan drives used wider .315" tape.
Travan and SLR
Personal computer magnetic tape backup has long been superseded by flash drives and the Internet. However, the two QIC formats that survived the longest were 3.5" Travan minicartridges and the 5.25" SLR data cartridges. Most drives supported cartridges one generation back. See
