Magnetic disk recording and reproducing apparatus

摘要

A thin film magnetic head includes a slider and thin film magnetic transducers, the slider supporting the thin film magnetic transducers. At least one of these thin film magnetic transducers is a magnetoresistive read element. The surface resistivity rho of the magnetic film of the magnetic disk is within the range of rho >/=0.03 OMEGA xcm. Electric leak from the thin film magnetic head to the magnetic disk and electric discharge between these two are prevented.
