Globalstor GSTDAIT-2

Commitment

Ait-2 is the 2nd generation of AIT products from Globalstor Data, illustrating Globalstor Data’s commitment to advancing this tape technology into the next millennium. As data storage requirements increase, you can be confident AIT will be there to fulfill your needs. AIT-2 is also fully read and write backward compatible with AIT-1, insuring your data will be accessible for years to come.

Performance

With a 50 GB native capacity per tape and a 60 MB/s native transfer rate, AIT-2 is twice the speed and transfer rate of our original AIT-1 tape drive. All in a compact 3.5″ half-height form factor, assuring AIT-2 will fit the demanding capacity and speed your application needs.

Reliability

Trellis Coded Partial Response (TCPR), the data encoding used by AIT-2, improves effective signal output, thus increasing read reliability. TCPR combined with the patented Hyper Metal laminate heads, which provide an additional increase to signal-to-noise ratio, provide AIT-2 with one of the highest levels of data integrity. When combined with the field proven mechanics, AIT provides an ideal solution for the demanding environments of HSM, tape array and robotics applications.

Memory In Cassette (MIC)

Incorporating a 65Kbit flash memory chip into the AIT-3 data cartridge provides an express route to daya, reducing average access time to fewer than 20 seconds. AIT-2 also features a remote-sensing, non-contact MIC reader, extending the life of the reader. MEDIA All AIT drives are designed for exclusive use of Advanced Metal Evaporated (AME) media, providing the patented “Diamond Like Carbon” (DLC) coating with a higher output metalization layer. AME media provides an extremely long head life with little to no cleaning required, and thousands of media uses.
