| DDS packs up to 20GB into one tiny cartridge (DGD150P). This ability is derived from the helical scan technology developed by Sony. Long-term archival storage and a low error rate, Sony DDS tapes employ a magnetic material that has outstanding magnetic transfer characteristics. Key to this performance are Sony''s ultra-fine particles and anti-oxidation coating, which is comprised of HDA (High-Density Alloy), HESA (High Energy Stabilized Alloy), and MP+++ (Metal Particle). |
