MAGNETIC RECORDING HEAD, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To increase the internal transfer speed of a hard disk by enabling high-frequency current driving. SOLUTION: In a magnetic recording head having the multi-layer structure thin-film coil of two or more layers, flattening processing is executed by machine polishing on a thin-film coil forming surface, where a thin-film coil after the second layer is formed.
