reproducing head

In order to reproduce the higher audio frequencies it was necessary to run the tape at 1500 millimetres per second past the recording and reproducing heads.

The explanation is that in the early experiments the turntable with disc was mounted on the shop lathe, along with the recording and reproducing heads.

The position of the recording and reproducing heads, mounted alternately on the same two posts, could be adjusted so that several recordings could be cut on the same wax-coated strip.
