ABSTRACT:
A magnetic record reproducing method includes the steps of bringing a magnetic film, capable of producing a magneto static wave, into intimate contact with or proximity to the recording surface of a magnetic recording medium, causing the magnetic film to produce the magnetostatic wave, detecting any variation in wave number in the magnetostatic wave attributable to the magnetized signal of the recording surface, and converting the variation in wave number in the magnetostatic wave into an electrical signal.
