TDK LTO Ultrium 4 Data Cartridges
25 Aprile 2007 - 5:14PM
Business Wire
TDK Corporation (NYSE:TDK) 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 2007. 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. Main
features of the TDK LTO Ultrium 4 data cartridge 1. Finest-ever
Super Finavinx metal magnetic material realizes higher output power
2. Special base film with strong, ultra-smooth surface and
outstanding dimensional stability 3. High-precision ultra-thin,
dual-layer tape coating technology realizes stable output 4.
Electron-beam Curing EB binder and thermo-setting TDC binder
realize high durability 5. Original servo signal writing technology
enables read/write accuracy 6. High-precision cartridge mechanism
enables seamless drive/media interaction, for added reliability 7.
Write-once (WORM type) recordable LTO Ultrium 4 media will be
launched at the same time as rewritable media LTO Ultrium 4 data
cartridge D2407-LTO4 (memory capacity: 800GB capacity without
compression, 1.6TB with 2:1 compression.) D2407W-LTO4* (memory
capacity: 800GB capacity without compression, 1.6TB with 2:1
compression.) * WORM (Write Once Read Many) type * Product images
