Abstract
A cassette for a high performance tape drive is disclosed. A cassette shell having the same general external dimensions as an industry standard leader block tape cartridge (3480/3490) includes both a tape supply spool and a take-up spool. Two tape guides present a segment of tape to a cassette access port which can be closed by a sliding door to prevent contamination when the tape is not in use. A tape cleaning device and a spool locking device are incorporated into the cassette mechanism.
