mm) tape to give higher capacities. SLR SLR is Tandberg Data's name for its line of high-capacity QIC data cartridge drives. As of 2005, Tandberg was the only manufacturer of SLR/QIC drives in the world. The largest SLR drive can hold 70 GB of data (140 GB compressed). QIC-Wide A variant from Sony that uses a wider .315 inch (8 mm) tape and increases the recording density. QIC-Wide drives are backwards compatible with QIC tapes. QIC-EX QIC Extra, a modification to support longer tapes and thus more data by the Verbatim Corporation, was made possible by making the cartridges physically longer to accommodate larger spools. In many cases a standard QIC drive and backup package can use the extended length to store additional data, however in some cases an attempt to reformat a QIC-EX cartridge fails since the time taken to traverse the extra length triggers a timeout in the drive or controlling software intended to detect a broken tape. QIC-157 An interface standard for tape drives using the ATAPI (IDE) interface.
