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.

Easy-to-Handle, High-Precision,
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.
