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.

data written in the opposite direction to its neighbor. Since its introduction, it has been widely used, and many variations exist. There is a QIC trade association that publishes QIC standards which include interfaces and logical formats. To a very large extent it was the efficiency and openness of this organization which encouraged hardware and software developers to use this type of drive and media.

end has a small beginning or end of tape hole which is detected by an optical sensor, and an "early warning" hole further from each end. If a defective drive—for example with fluff in a sensor—winds the tape past the BOT or EOT marker, the tape will detach from the spool and the cartridge will be unusable unless it is reattached.

inch (6.35 mm) wide and anywhere from 300 to 1,500 feet (91 to 457 m) long. Data is written linearly along the length of the tape in one track (mostly on pre-1980 equipment), or written "serpentine", one track at a time, the drive reversing direction at the end of the tape, and each track's

The tape in a QIC cartridge is not physically attached to the reels and is never completely unwound. This is again different from other cassettes or cartridges, which generally have some form of clip anchoring on at least one end of the tape. To ensure that the tape is never completely unwound, each

However, because the tape is belt-driven, seeking back and forth can eventually cause the tape to become unevenly tensioned. It is therefore necessary to periodically retension the cartridge. This is accomplished by winding the tape from beginning to end and back in one operation, allowing the belt
