Originally introduced by 3M in 1972, the Quarter Inch Cartridge (QIC) market came to be dominated by Tandberg Data with their SLR and MLR products.

Although no longer being manufactured, Avax can still offer the complete range of drives as refurbished units.

Note –  The Flash Card based Magnetic Tape Replacement is available as a ‘Plug & Play’ replacement for legacy SLR drives
