Digital Linear Tape
DLT
<storage> (DLT) A kind of {magnetic tape} drive
originally developed by {DEC} and now marketed by {Quantum}.
DLT drives implement the {Digital Lempel Ziv 1} (DLZ1)
{compression} {algorithm} in a combination of {hardware} and
{firmware}. They use a popular chip by {Stac} (now {hi/fn})
to do the string searching. Counting, sorting and {Huffman
coding} are done in firmware (with hardware support for the
Huffman algorithm?).
In April 1997 DLT drives can transfer 5 {megabytes} per second
and can store 35 {gigabytes} on a single cartridge.
Compression might roughly double these figures.
