Control Data 92185 Keystone magnetic tape transport

UvA Computer Museum catalogue nr 01.48

---

This tape drive accomodates both PE (phase encoded) and GCR (Group Coded Recording, 6250 bpi) tapes, with 37 MB and 123 MB of formatted capacity, respectively (on a 2400 ft reel). It can be operated in both streaming and start-stop modes. Compressed air is used for air bearings, however there is no difficult-to-maintain vacuum system for tape slack buffers. Instead, tape tensioning is controlled by solid-state sensors.
Our unit has provisions for both standard Pertec interfacing and SCSI.
