ⓘ Digital Data Storage

Digital Data Storage is a computer data storage technology that is based upon the digital audio tape format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data.

Cartridge DDS uses tape with a width of 3.81 mm with the exception of the latest formats, DAT-160, and det-320, which are 8mm wide tapes. Initially, the tape 60 m 197 feet or 90 meters 295 feet. in length. Advances in materials technology have allowed the length increases significantly in subsequent versions. A DDS tape drive uses helical scanning recording, the same process is used a VCR tape.

Backward compatibility between newer drives and older patrons are not sure of the compatibility matrix provided by manufacturers will need to consult. Usually the drives can read and write tapes in the previous format, generation, most, but not all know how to read and write tapes from two generations before. Note the HPP article that the new standards tape is not only more tapes, DDS-2, for example, the path narrower than with DDS-1.

At one time, the SDS fought against Linear Tape-Open LTO, Advanced intelligent Tape AIT, VXA, and Travan formats. However, AIT, travan and VXA is not the mainstream, and the capacity of LTO is significantly superior to the latest standard DDS, DDS-320.
