Greater Capacity in a Tiny CartridgeSony’s DAT320 (DGDAT320R) cartridge offers the storage capacity of 160GB (native) and 320GB (compressed).Thanks to Sony’s technological experience as a Metal Evaporated media expert for over 20 years, DAT320 provides greater recording density in a small cartridge by adopting our ME and helical scan technologies already proven reliable in our AIT format. DAT Format, De-Facto Standard for Small-to-Midsize StorageWith entry-level storage capacities and high reliability, the DDS/DAT format has the largest installed base of any tape technology and is the de-facto standard for small and medium sized businesses.The DAT320 generation offers greater capacity and faster transfer speed but maintains its small size providing space, cost and energy saving benefits. |
Sony’s Metal Evaporation TechnologySony’s metal evaporation technology, derived from the development of the AIT format, delivers newly developed super-fine magnetic layer that is optimized for DAT320. This enables the tape to have higher coercivity and greater magnetic flux density, resulting in high output and low noise level.The carbon protective layer deposited on the magnetic layer ensures a strong wear resistance, providing a higher durability. The application of a lubricant layer provides lower friction which reduces head wear. Again, Sony’s expertise in metal evaporation technologies has led to the development of this highly reliable next generation. |

Cartridge with High PerformanceSony’s low torque cartridge technology helps minimize the torque effect during winding. From experience as the DDS/DAT manufacturer, Sony specially designed hub and shell as well as upper sheet and lower sheet newly designed for the wide tape to help improve cartridge strength and ensure smooth tape running. |
