Die Spezifikationen des Fuji DDS4 DATA Bandes (2004)

DDS (= Digital Data Storage) has become the world standard for storing and backing up computer data on tape, and now you can enjoy even higher capacity, higher output, and higher reliability than ever before. The ATOMM technology used to achieve reliable, high-density recording on compact Fujifilm DDS3 and DDS4 data cartridges has evolved, and the result is a new generation of DAT72-compliant, metal-coated DG5-170M tapes with 36GB capacity (72GB with 2:1 compression) and high reliability.

Anmerkung :

DDS-Bänder sind keine DAT-Bänder und DAT-Bänder können nicht als DDS Bänder verwendet werden. DDS-Bänder sind wesentlich langlebiger und deutlich genauer spezifiziert und dadurch sicherer und auch teurer. DAT Laufwerke können nur bis 120m Bänder beschreiben und lesen und mechanisch betreiben. Die dünneren DDS Bänder oberhalb von 120m überleben die DAT Mechanik nicht.


When the surface of a tape is uneven, head contact is poor. This 'spacing loss' results in lower output. Newly evolved Fujifilm ATOMM technology creates an even smoother tape surface than in the past, ensuring improved head contact for consistently high output.

Fujifilm's DDS4 offers up to 20GB of uncompressed storage capacity (40GB compressed) in combination with a drive-dependent maximum transfer rate of 3MB/Second.

A further factor contributing to the DDS-4's reliability is the innovative 4S (Symmetric Slider Spring Structure) which provides smoother movement of the redesigned high-rigidity cartridge's slider section. Taken together, these innovations create a huge leap forward in backup and long-term archiving.

Although 4mm systems (real width = 3,81mm !!) have error-correction, avoiding errors in the first place is the best solution. An extremely smooth base film and super-calendering techniques give the magnetic layer a mirror finish to reduce the spacing loss that causes errors. Combined with the tapes' high output, this results in an extremely low error rate.

Both DDS data cartridges feature SDR (Super Durability and Runnability) backcoating with a very low friction coefficient, assuring smooth transport even with the complex transport modes and mechanisms of these systems. Thanks to their outstanding static resistance, these data cartridges prevent dust accumulation, maintaining their exceptionally low error rate over an extended working life.
