Abstract
A magnetic head for reproducing a signal recorded on a recording medium, includes a substrate, a magnetic head core provided on the substrate, having a magnetic gap, and a magnetoresistance device provided on the magnetic head core. The magnetic head core is provided in such a manner that a thickness direction of the magnetic head core around the magnetic gap is substantially the same as a track width direction of the recording medium.
