Discrete Three Head Cassette Recorder (1981-84)
The ZX-7 features Nakamichi Discrete Head Technology in which record, play and erase heads are mechanically as well as electrically independent.
Mechanical independence reduces crosstalk and allows each head to be contoured for smoothest response.
Of even more importance, the mechanically independent heads of the ZX7 can be adjusted individually for proper azimuth and allow the user to readjust record-head azimuth to correct for differences in tape path from cassette to cassette.
