Tape density: 200/556/800 bpi
Tape speed: 75 ips (Forward/Reverse)
225 ips (Rewind)
Data rate: 60 kHz at 800 bpi
Size: 30"W x 25"D x 69"H (in cabinet)

The TU30 Magnetic Tape Transport was a magnetic tape drive from DEC; it required a controller to connect to its host machine. The transport section was a D3030 OEMed from the DATAMEC division of Hewlett-Packard. It was used with the PDP-8 (with the TC58 Tape Control Unit), the PDP-9 (with the TC59 Tape Control Unit), the PDP-15 (ditto), and the PDP-10 (with the TM10 Magnetic Tape Control).

It could store 5-23 Mbytes on a 2400' 0.5" wide magnetic tape carried on a standard 10-1/2" reel. The TU30 supported either 7-track operation at 200, 556, and 800 BPI, or 9-track at 800 bpi.

The tape transport utilizes a single pinch roller capstan, with vacuum columns. The TU30 drive contains a fair amount of electronics, in the form of FLIP CHIP modules in a 19" wide wire-wrap backplane (mounted horizontally in the base of the cabinet).
