Digital Linear Tape (DLT; previously called CompacTape) is a magnetic tape data storage technology developed by Digital Equipment Corporation (DEC) from 1984 onwards. In 1994, the technology was purchased by Quantum Corporation, who manufactures drives and licenses the technology and trademark. A variant with higher capacity is called Super DLT (SDLT). The lower cost "value line" was initially manufactured by Benchmark Storage Innovations under license from Quantum. Quantum acquired Benchmark in 2002.
