Welcome to our DLT Page.
DATASURE SERVICES provides a comprehensive range of DLT solutions, from automated tape libraries with high perfomance and capacity to stand alone drives
We have DLT media including TypeIIIXT and TypeIV
High transfer rates, and capacity make DLT highly suitable for HSM.
Brief history:
Originally developed by Digital Equipment Corp. as TK50 backup system for the MicroVax II by putting 1/2" tape in a cartridge with 94MB of storage. Improvements in density, drive, and more tape in cartridges. Storage division was bought by Quantum in 1994... Capacity now up to 35GB and 50GB on the horizon.
DLT (trademark of Quantum)
The cartridges contain only a supply reel for the tape, and the take up reel is inside the drive, leaving more room for tape inside the cartridge. The head guide assembly uses a series of six precision rollers to move the tape in a gentle arc and minimize tapewear. The rollers contact only the back of the media, not the recording surface.
DLT 7000 series Increased performance and backwards compatible
Increased density in the DLT7000 series drives while still using the TypeIV media by tilting the recording/read head to narrow the track width to .175 mils and record and read at an angle, using Symetric Phase Recording TM which eliminates the need for guard bands preventing cross band interference between the channels as in the DLT4000 format. (see below)
The 7000 series drive read/write head shifts to a vertical position to read previous generations of media (see below).
