In October 1978, NEC announced the TD1000 Series of compact magnetic tape units for OEM. The Series could be mounted in a 19-inch standard rack and featured low noise of 60phon max. It was also equipped with an automatic tape mounting mechanism and cartridge mounting mechanism, and had outstanding maintainability with self-diagnosis by the control section using firmware and the ability to conduct maintenance from the front side (front access system).
Numerous models were available, differing in terms of recording system, recording density and tape running speed.
In September 1979, NEC announced the TD140X Model which increased the tape running speed of the above model from 75inch/s to 100inch/s.
