Abstract:
A thin-film magnetic head having a thin-film magnetic write head and a thin-film magnetic read head, wherein the thin-film magnetic write head comprises:a lower core layer; an upper core layer magnetically opposed to the lower core layer; a nonmagnetic gap layer disposed between the upper and lower core layers, the nonmagnetic gap layer having a surface with a curvature within a tolerance for writing data as signals reliably-readable onto at least one reversed magnetization region of a recording medium; and wherein the thin-film magnetic read head comprises:a lower shielding layer; an upper shielding layer; and a reading gap layer disposed between the lower and upper shielding layers, the reading gap layer providing a magnetic-field read section having a surface region, wherein the surface region fits within the at least one reversed magnetization region.
