Abstract :
This paper begins with a review of previously published work on film recording heads and then reports on write-read experiments with single-turn film heads at a medium velocity of 40 m/s (1575 in/s). A typical film head is compared to a conventional ferrite head with regard to readback pulse shape, transition-density response, and efficiency. The results are in agreement with theoretical predictions.
