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 Huffmanencoding 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.
