The TU72 Magnetic Tape Drive was a 9-track auto-loading magnetic tape drive sold by DEC. It was OEMed from Storage Technology Corporation; apparently the STC 3650E model. It supported 9-track operation at 1600 bpi (using PE encoding) or 6250 bpi (using GCR encoding).
For use on the PDP-10, it used a TX02 Magnetic Tape Controller, which in turn was connected to a DX10 Data Channel, or a DX20 Programmed Device Adapter.
The tape transport utilized a single capstan, with air bearings, and two vacuum columns.
