Scalable Linear Recording

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 140GB compressed (70GB uncompressed, or native). The term SLR is now often used to refer to QIC tapes, as they are the only drives still manufactured that use them.
