Thin-film magnetic head with separate recording and reproducing gaps

Abstract

A thin-film magnetic head includes a recording unit for generating a magnetic flux at a recording gap, which flux is used to magnetically record information on a magnetic disk, and a reproducing unit for reproducing information at a reproducing gap from the magnetic disk, wherein the recording unit and the reproducing unit are integrated with each other in a state where an interval between the center of the recording gap and the center of the reproducing gap is equal to or less than 2 .mu.m. In addition, a thin-film magnetic head includes a recording unit for generating a magnetic flux used to magnetically record information on a magnetic disk, the recording unit having a soft magnetic layer used as one of magnetic poles for generating the magnetic flux, and a reproducing unit for reproducing information from the magnetic disk, the reproducing unit being separated by the soft magnetic layer from the recording unit, wherein the soft magnetic layer has a saturation magnetic flux density greater than 1.3 tesla.
