High-Performance Metal Magnetic Particles and

an Ultra-Thin Magnetic Layer Ensure a Low Error Rate

ATOMM-II technology uses magnetic particles that are approximately half the size of the particles used in first-generation ATOMM technology. The new particles also have an energy level that is approximately 70% higher, with retentivity of 370 mT and coercivity of 183 kA/m. In addition, the extreme thinness of the magnetic layer reduces self-demagnetization loss, and ensures high output and a high C/N ratio in the short wavelength range. DP Series tapes also feature a super-smooth magnetic layer that reduces spacing loss, and specially formulated lubricants that improve tape travel over heads and guides. The result is reduced micro-dropouts and an exceptionally low error rate. Despite having a width of only 6.35mm, DP Series tapes can record massive amounts of digital data, and provide the high image quality that broadcasters demand.

Superior Transport Stability, Durability and

Storage Characteristics in Demanding Environments

ATOMM-II technology allows the non-magnetic lower layer to be impregnated with lubricants that control tape and head wear, ensuring that the tape surface is optimally lubricated even during repeated playback and rewind operations. Together with a high- molecular binder material that improves magnetic layer durability, the lubricants enable the tape to withstand extended still/standby and high-speed shuttle operation, as well as adverse ENG/EFP field conditions, yet still offer superior transport stability and durability with minimal head clogging. To ensure superior long-term storage characteristics, metal magnetic particles are uniformly coated with a special oxidation-resistant material, and tape shrinkage-preventing technologies are used to prevent the track pattern deformation that can cause tracking errors.

High-Rigidity Cassette Shells

Tightly sealed high-precision, high-rigidity cassette shells prevent tape deformation and damage, promote stable tape transport, and shut out dust and dirt to help ensure a low error rate. They also feature large clear windows that allow the amount of remaining tape to be confirmed at a glance, and colored lids and transparent hard cases that make it easy to differentiate DP121 and DP1001 cassettes from one other.
