Abstract

PURPOSE:In order to realize the high speed in rise-time of the signal current, through achieving the high-density recording, by way of installing the pulsetrans and condensor being feeded with the electric current after alternatively selecting, with respect totthe pulse-trans to be used for the address-matrix and so on of magnetic recording device.
