1-pack DVD+r47 Media 4.7GB TDK's new DC4-150 data cartridge is an ultra-high-density DDS-4 cartridge optimized for use in the newest Digital Data Storage drives The cartridge achieves an ultra-reliable native storage capacity of 20GB (40GB compressed) The increase in capacity over existing helical-scan DDS formats is made possible by reducing track pitch from 9.1 to 6.8 microns and increasing cartridge tape length to 150 meters The DC4-150 cartridge is specifically engineered to take full advantage of the DDS-4 format, with a higher coercivity MP Metal Particle tape formulation and 3DC binder system, which creates an extremely strong three-dimensional web surrounding each pure-metal MP particle on the recording layer The rugged, web-like structure ensures that magnetic particles are firmly anchored, densely packed and uniformly dispersed on the tape surface
