The Sony 120M DDS2 data cartridge DGD120P has a native capacity of up to 4GB and a compressed capacity of up to 8GB. The Sony DDS 2 tape is 120m/394feet long, is a 4mm wide and is read/write compatible with any DDS-2, DDS-3 or DDS-4 drives. Drives that use the DDS-2 120m data cartridge are recommended to use the DDS Cleaning Cartridge to keep the drive clean. With outstanding durability and tape travel stability Sony's HCL (High Cross Linkage) binder raises reliability and durability to withstand the stress of repeated tape use. In addition, Sony's RDP mechanism sandwiches the tape between textured sheets to support smooth tape winding. The cartridge lid is made of strong plastic to protect the tape against accidental drops or mechanical shock. Unique low torque cartridge As tape winds onto a reel, torque rises along with diameter. To minimize this torque effect in fast-forward and rewind search modes, Sony uses special designs for the DDS hubs, lower sheet, and lower shell. The shell also improves overall cartridge strength to minimize potential deformation under external stress.Thin dual-layer coating technology Sony DDS3 and DDS4 tapes use a dual-layer coating comprising an ultra-thin magnetic layer and a nonmagnetic layer. The ultra-thin magnetic layer provides high output even in the high frequency range essential for high-density recording. The non-magnetic layer creates a smooth surface to support tape travel stability and durability. Ultra-fine magnetic particles Although smaller magnetic particles are more difficult to disperse within the binder, Sony's high dispersion technology achieves outstanding results even with ultra-fine particles.
