Introduction¶
The ND 543 — Magnetic Tape Drive, the ND 537 — Magnetic Tape Formatter, and the ND 560 — Magnetic Tape Controller constitute one of the leading minicomputer tape systems in the market. The formatter and drive are delivered by Storage Technology Corporation, a well reputed producer of computer peripherals.
Features¶
- Up to four drives on each controller
- Two densities — 1600 and 6250 bpi
- Speed 125 ips
- In a multiple drive system, the formatter can handle a mixture of densities

Product Description¶
A two-phase digital tachometer in the capstan motor provides precise tape positioning and stop-lock control, at an accuracy of 0.00565 inches.
For speed control, tack pulses are compared to a crystal clock pulse.
In addition to automatic thread/load, extraordinarily accurate tape loading is assured by a minimum length, straightshot, gravity-assisted tape path. Tape acceleration is kept to a minimum by a microsequencer-controlled linear reel servo system.
Tape drag and tape edge damage is minimized by the use of hydrostatic air bearings at all critical points. A hydrostatic rewind foot prevents tape and head wear during high speed rewind. And a unique tape footage counter, in conjunction with the digital tack and microsequencer, smooths tape acceleration and deceleration for faster and gentler rewind.
