 Quantum SDLT 220 Overview | Quantum`s SDLT 220 incorporates multiple advances in technology, and achieves huge increases in capacity and transfer speed. More importantly, this is the only architecture that provides a viable path to greater capacity and performance developments, while maintaining compatibility with the world`s largest installed base of DLTtape≥ cartridges. The SDLT 220 provides the best possible protection for the long-term success of your investment in data storage solutions. | | Benefits
- Native capacity of 110GB at 11MB/s transfer rate
- 2:1 Compression allows 220GB at 22MB/s
- Technology designed to reach 2TB capacity at 160MB/s
- Fully backward read compatible with DLTtape IV cartridges
- Advanced Metal Particle Media allows the optical servo tracks onto the reverse side of the tape
- 100% of tape`s magnetic side freed up to record data
- No need for magnetic pre-formatting
- Laser Guided Magnetic Recording combines best of optical and magnetic technologies
- Pivoting Optical Servo increases high duty cycle reliability
- Magneto-Resistive Cluster Heads for the highest data density
- High efficiency PRML Channel creates more tracks on the tape
- Increased media capacity provides easier use and lower cost of ownership
