Digital Linear Tape
     
         (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
        encoding} 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.
