DLT uses linear serpentine recording with multiple tracks on half-inch (12.7 mm) wide tape. The cartridges contain a single reel and the tape is pulled out of the cartridge by means of a leader tape attached to the takeup reel inside the drive.
DLT (Digital Linear Tape) technology was developed by Digital Equipment Corporation in the early 1980ís. The initial TK50 drive could store only 94 MB of data however today through technological upgrades we now have DLT tapes ranging from 10 to 800 GB in native capacity. The data on a DLT tape is stored in a linear format with multiple tracks on a half-inch wide tape. The DLT tape is a metal particle tape. Media can last up to 30 years under specified environmental conditions. DLT tapes are ideal for small to medium LAN networks and also work well for hierarchal storage management applications, workstations and midrange systems.
