DLT
Digital Linear Tape: DLT is a mass storage technology that uses special removable magnetic data tape cartridges. Data must be stored sequentially with DLT so access time to restore individual files is low. High end tape drives can write data to tape at transfer speed compariable to hard drive speeds. DLT can store data reliable for up to 80 years under a controlled environment.
