Description:
DDS packs up to 20GB into one tiny cartridge (DGD150P). This ability is derived from the helical scan technology developed by Sony. Longterm 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 Sonys ultrafine particles and antioxidation coating, which is comprised of HDA (HighDensity Alloy), HESA (High Energy Stabilized Alloy), and MP (Metal Particle). DDS tapes are made with a nonmagnetic layer above the base film to enhance the performance of the magnetic layer. Compared to DDS 3, DDS 4 uses an even thinner nonmagnetic layer attaining high output with improved surface smoothness.
