Abstract

A candidate technology offering a mature high-performance and low-cost approach to automated mass storage is discussed. It utilizes 0.5-in video magnetic tape, industrial-quality drive mechanisms, and broadcast video robotics. Accompanying software provides logical volume and file management and appears to host systems that are as large but have a slow-access online diskfile system. Cassettes with over 6 GB of storage and drives operating at up to 4 MB/s sustained are incorporated in a robotic assembly holding 600 cassettes. The system has a capacity of nearly 4 TB and occupies only 18 ft/sup 2/ of floor space. A full-load media cost is about $6000. Advances in data-transfer rate and packing densities will at least double future system speed and capacity.<>
