DST cartridges range from 50 to 330GB and are suited for uncompressed digital video (movies, commercials, etc.) and high-resolution images as well as general data backup for huge databases. Ampex's Data Instrumentation Systems (DIS) tape technology is a counterpart line that provides optional modes and interfaces for data acquisition devices. See magnetic tape.
