One space-saving AIT-4 cartridge holds up to 200GB native, 520GB compressed, & offers a fast data transfer rate of 24MB/s (native). Sony's drive technology & AME tape technology come together in the AIT format to deliver a remarkable combination of high reliability & high recording density. Since Sony introduced the format in 1996, AIT has gained a reputation for high reliability & high capacity in a space-saving form factor. In the AIT format Sony has applied advanced technologies refined & proven over many years. 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. 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 & the tape itself. WORM (write-once read-many) allows data to be written & added but not overwritten or erased. This protects valuable data against accidental erasure & prevents alteration of archived data files. Sony SDX4-200C features non-contact R-MIC (Remote Memory In Cassette) chip technology. This internal memory can simplify media management & accelerate access in library environments, compared to conventional bar-code methods. Features High storage capacity of up to 520GB compressed data (200GB native) Fast data transfer using efficient Helical Scan technology, up to 24MB/sec sustained native transfer rate Proven reliability & durability with a 30 year media life thanks to AME II technology (Advanced Metal Evaporated) Quick access provided by AIT's unique Remote Memory-In-Cassette (R-MIC) incorporated into the cartridge Available in Write-Once Read-Many (WORM) format to protect valuable data against accidental erasure & prevent alteration of archived data files Cleaning tape: SDX4CL
