DDS or DDS-1 backup tape media cartridge

The aboriginal implementation of the DDS1 backup tape format used 60 metre tapes for a 1.3GB capacity. Influence was upgraded to 2GB by extending the tape length to 90m, with no other changes in the tape formulation or the vinyl format.

DDS-2 backup tape media cartridge

In disposal to escalation the DAT technology, the power was increases from 2GB to 4GB in DDS2 backup tape cartridge. The media length was increased to 120m and a just out higher coercivity MP+ formulation was introduced. a thinner tape was required to distance the 120-meter target. DDS 2 backup media tape was reduced to 6.9 um thickness, compared to 9.0 um for DDS-1 backup attractive tape.

DDS-3 backup tape media cartridge

The transition from DDS-2 to DDS-3 brought the largest energy caper in the anecdote of DAT technology, a 3x improvement over the preceding generation. The DDS3 backup tape cartridge has native faculty of 12GB. The DDS 3 format was derived from two guide media improvements: a higher-coercivity (1700 oersted vs. 1530 oe) history of the MP+ formulation used in DDS-2 media. The tape length was increased to 125m. The enhanced magnetic properties of the higher coercivity MP++ media supported a doubling of the linear bit density to 122 kbpi.

In DDS-3 backup tape media cartridge again benefited from a indicative non-media technology enhancement: the debut of current highly efficient Limited Response Maximum Likelihood PRML announce channel technology has been introduced. This contributed to besides increased capacity.
DDS-4 backup tape media cartridge

The DAT technology reached the 20GB per cartridge entry with DDS4 backup tape media cartridge. In DDS-4 backup tape media cartridge an improved MP media formulation was introduced along with longer length tape. For handling the higher track densities of the DDS-4 format, a higher output MP formulation designated MP+++ was developed.

Fifth time of DDS DAT 72

DAT72 was built on the technology foundation of previous DDS media format. The native authority of DAT-72 is 36GB. In DAT72 backup tape media cartridge virgin MP++++ formulation has been used.

In DAT72 the tape length was increased to 170 meters. The disc density has been increased from 122 to 162 kbpi along with increased track density.

DAT160 the 6th procreation of DDS

The sixth date of DAT 160 products corner a native potency of 80GB and transfer rates in the region of 5MB/s.

DAT 7th Generation

The DAT seventh age testament hold native competence of 150GB and native transfer degree of 8 MB/s.

DAT 8th Generation

The DAT eighth interval will accept native ability of 300GB and native transfer standard of 16 MB/s.
