Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") is a magnetic tape data storage format introduced by 3M in 1972, [1] with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape.
Scalable Linear Recording is the name used by Tandberg Data for its line of QIC based tape drives. The earliest SLR drive, the SLR1, has a capacity of 250 MB, while the latest drive, the SLR140, has a capacity of 70 GB. The term SLR is often used to refer to QIC tapes, as for many years they were the only drives that used them before Tandberg ...
Prior to this, Archive was a leading vendor of the very popular quarter-inch cartridge (QIC) format which was a popular distribution format for Unix workstations and servers. For example, software for the Sun-3 (running the Motorola 68K family ) and the Sun-4 (based on SPARC processors) was most commonly distributed on QIC media before CD-ROMs ...

The DC100 tape cartridge was a scaled-down version of the DC300 cartridge pioneered by 3M, and represents an early version of what is now referred to as the QIC Mini Cartridge. [ 4 ] 3M was the exclusive source of DC100 tapes, [ 5 ] while drives were manufactured by 3M and several third parties.
Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track, later 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) [1] and IBM 3592 series.
DDS tape drive (bottom). Above, from left to right: DDS-4 tape (20 GB), 112m Data8 tape (2.5 GB), QIC DC-6250 tape (250 MB), and a 3.5" floppy disk (1.44 MB). A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally ...
