April 25, 2007

TDK Corporation today announced that its two new fourth-generation LTO Ultrium 4 data cartridges are the world's first to have passed certification testing by the CVE (Compliance Verification Entity), the organization responsible for LTO standardization. TDK will begin shipping its rewritable D2407-LTO4 and recordable D2407W-LTO4 media products in May.

A recording media expert, TDK has always worked in close concert with drive manufacturers to develop media products that perform seamlessly with the hardware devices in which they're used. Through its collaboration with hardware manufacturers, TDK was able to create ultra-performance LTO Ultrium 4 media, and become the world's first to pass strict certification testing by the CVE.

As digital networks grow in scope and complexity, the volume of data that must be managed continues to increase considerably, creating demand for storage solutions with higher capacities and faster data transfer rates than previous systems. LTO Ultrium 4, with its large 800GB capacity (1.6TB with 2:1 compression) and rapid 120MB/s data transfer rate (240MB/s with 2:1 compression), is the newest backup system for today's high-speed, large-capacity servers.

To achieve its remarkable capacity, the LTO Ultrium 4 data cartridge utilizes tape with 12.65mm width and 896 recording tracks (compared to 384 tracks for LTO Ultrium 1, 512 tracks for Ultrium 2 and 704 tracks for Ultrium 3). The tape thickness has been reduced to facilitate incorporating more tape into the cartridge. As a result, considerably greater precision, performance and durability are required.

TDK's LTO Ultrium 4 D2407-LTO4 and D2407W-LTO4 data cartridges feature the most advanced magnetic material and tape technology, leveraging the company's longstanding expertise in the development of LTO Ultrium media and other recording media products.

Several key technologies enable TDK LTO Ultrium 4 tapes to achieve ultra-stable read and write signals. These include specially designed, ultra-fine Super Finavinx metal particles with high output power, an ultra-thin, dual-layer tape coating technology that controls the thickness of the magnetic layer to the nanometer order, and a special servo writer that's used to record high-precision servo signals. To achieve maximum performance and seamless interplay with the drive, the advanced cartridge mechanism includes a high-precision leader pin, new multi-strut construction for the reel hub to realize high circular precision, and other advancements.

The aforementioned features and technologies enable the D2407-LTO4 and D2407W-LTO4 LTO Ultrium 4 data cartridges to meet today's most demanding data storage requirements.
