Sony SDX2-50W SDX250W//AWW User Manual

Sony Storage Media

Thanks to Sony’s technological expertise, AIT achieves extraordinary data  
densities in a small 8mm cartridge. It’s a space-saving solution that’s 
much more compact than other formats of equivalent capacity.  
For example, the 200GB (native capacity) SDX4-200C cartridge is only 
37% the size of a single-reel.  

High capacity, small form factor

Building on AIT’s established technology, Sony raises data density even further in AIT-4 to achieve compressed  
capacity of 520GB. AIT-4 media’s smooth surface improves electromagnetic conversion characteristics, while a  
newly developed lubricant reduces friction. An enhanced protective coating minimizes wear on heads and the  
tape itself.

AIT-4 raises capacity to 200GB/520GB

The proven reliability of AIT is also available in a write-once format. WORM (write-once read-many) allows data 
to be written and added but not overwritten or erased. This protects valuable data against accidental erasure 
and prevents alteration of archived data files.

Write-Once Read-Many (WORM) format available

Sony has already achieved areal data density of 11.5Gbpsi in the  
laboratory. For the AIT format, this translates into 2TB capacity per  
media package. The AIT format’s migration path is built on this kind of 
ongoing innovation.

Path to the AIT future

Sony SDX4-200C, SDX4-200W, SDX3-100C, SDX3-100W and SDX2-50W 
products feature non-contact R-MIC (Remote Memory In Cassette) chip 
technology. This internal memory can simplify media management and  
accelerate access in library environments, compared to conventional  
bar-code methods.

R-MIC (Remote Memory In Cassette)

In the AIT format Sony has applied advanced technologies refined and proven over many years. Since the format’s 
debut in 1996, AIT has employed AME (Adanced Metal Evaporated) tape, and received high acclaim from data  
storage professionals for the outstanding reliability of its technology. AME II, the successor of AME, was developed 
for AIT-4. AME II enables AIT-4 media’s extraordinary areal recording density as well as its high durability. AME II 
uses a new method for applying the magnetic layer to the tape, an enforced coating layer, and a newly developed  
lubricant for stable operation.
