METHOD AND APPARATUS FOR RECORDING TRANSIENT SIGNALS

摘要

A method and apparatus for recording transient signals of extremely short duration on a thin film medium. A uniaxially anisotropic film having easy and hard axes of magnetization is located adjacent an input signal conductor and a scanning conductor. The scanning conductor is energized to produce a high intensity field which sweeps along the film parallel to its hard axis, while the input conductor applies the signal to be recorded to the film along its easy axis. The film may be exposed to a constant gradient field to insure that the recording faithfully represents the amplitude of the input signal.
