Chapter 4. Tape Drive Specifications
TR-4 1/4-inch tape cartridge technology offers fast, efficient, high capacity storage
in a compact, easy-to-remove hard-shell package. This mass-storage technology
evolved from the original reel-to-reel 1/2-inch tape storage medium. Storage
capacities increased from 60 MB on 9 tracks (QIC-24, 1982) to the 4 GB capacity
achievable with the tape cartridge.
