The TU70 Magnetic Tape Drive was a 9-track auto-loading magnetic tape drive sold by DEC. It was OEMed from Storage Technology Corporation; the STC 3470 model. The TU70 supported 9-track operation at 800 bpi (using NRZI encoding) or 1600 bpi (using PE).
For use on the PDP-10, it used a TX01 Magnetic Tape Controller, which in turn was connected to a DX10 Data Channel, or a TX02 Magnetic Tape Controller, which connected to a DX20 Programmed Device Adapter.
The tape transport utilized a single capstan, with air bearings, and two vacuum columns.
