MAGNETIC RECORDING/REPRODUCING HEAD

PROBLEM TO BE SOLVED: To provide a thin film magnetic head having excellent recording performances such as high recording magnetic field or high recording efficiency in a narrow track width of 2 μm or lower, and capable of highly accurately forming a narrow magnetic pole pattern. SOLUTION: An upper magnetic core to determine a recording track width is constituted of two parts, i.e., a first part 110 exposed on a medium opposite surface, and a second part 111 not exposed on the medium opposite surface, but larger in witch and film thickness than the first part 110, a tip of which is arranged between the surface opposite to the medium and a point 112 of throat height = 0.
