The Digital Audio Tape DAT technology is the most prolific of all tape technologies. The DAT tape was formerly manifest as DDS Digital Info Storage. Over 15 million DAT drives annex been shipped on account of the fundamental products were introduced in 1989 and aggrandized than 6 million owing to 2000. This gives rise to a conservative estimate of a 6-million user installed base. The HP StorageWorks DAT160 tape impel is the modern edition to the DAT family. It was launched by HP in Jun 2007. The DAT-160 ride is an evolution of existing DAT technology and has yet in everyday with the preceding five generations of DAT. It is estimated that there are over 6 million DAT tape drives currently installed worldwide. The DAT media tape cartridge is the Low-cost media and provides its customers the lowest worth of ownership.

The HP StorageWorks DAT 160 tape has 80-GB native energy and up to 160 GB with 2:1 news compression. The HP DAT-160 has a transfer standard of 6.9 MB/sec native, over 13.8 MB/sec with 2:1 counsel compression. The DAT160 provides encircling 160 GB backing up in under 4 hours. Higher power can be achieved exclusively by using wider tape for DAT160, nevertheless all the more provides backward dash off and construe compatibility with DAT72 and DAT40 media. This can be done by having two independent threading mechanisms and tape paths inside the device.

DAT 160 supports HP StorageWorks One Press-stud Catastrophe Recovery Meaning when used with the substantial software and HP ProLiant servers, allowing complete rebuild of a server from a unmarried backup tape. It and includes Single Server Edition of HP Facts Protector Definitive backup/recovery and disaster recovery software. DAT-160 media cartridge is supported on a broad span of operating manner and backup applications.

The DAT160 media is aloof a wider novel of the DAT40 media using MP Metal Particle technology 150 m in length. This is the corresponding type of tape as has been shipping by reason of 1994 in DAT40 cartridges. It has a proven track log of reliability. However, in DAT160 media, wider account of the tape has been used to enable preferable capacity. A DAT160 handle accepts both sizes of media on the contrary threads them encompassing the drum in at variance ways.

Transfer degree on DAT technology is hell bent partly by the wrap angle (amount of tape wrapped enclosing the rotating helical recite drum) and the precipitation of rotation of the drum. The wrap angle of the DAT160 coerce is 180 degrees compared to sole 90 degrees for previous reproduction DAT technologies, so the DAT-160 guide in truth makes extended efficient application of tape in contact with the belief to access transfer rate. Extremely generations testament augmentation the drum speed.

The HP accession of using independent tape threading mechanisms was the breakthrough that enabled the DAT160 manage to compose and scan DAT-72 and DAT-40 media. When the conception of loading two deviating heights of cartridge with two antithetic tape widths was invented, HP used lingering pc simulation techniques to pattern the tape threading and routing for everyone tape type. The results of these simulations indicated that the example concepts were both practical and yielded positive levels of verge in allowing the plot to be successful.

The most laborious objection has been accommodating all the mechanical components in the physical period available. However, using the HP sample product drawing and testing methodology, the compelling mechanical solutions and enhancements admit been evolved. The robust engineering and side in these tape guides are the keys of a flourishing interchange.
