(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) compressionalgorithm 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.(1997-04-05)
