Abstract:
A method of manufacturing a magnetic head, comprising:forming a first magnetic core for recording by an electrodeposition process; and forming a second magnetic core for recording by an electrodeposition process, said second magnetic core disposed adjacent the first magnetic core, said first magnetic core and said second magnetic core separated by a recording gap, wherein at least one of said first magnetic core and said second magnetic core comprises a first plated magnetic layer and a second plated magnetic layer, said first plated magnetic layer disposed nearer the recording gap than said second plated magnetic layer, and wherein a saturation magnetization of said first plated magnetic layer is greater than about 1.7 tesla, and wherein a resistivity of said first plated magnetic layer is less than a resistivity of said second plated magnetic layer, and wherein a thickness of said first plated magnetic layer is less than a thickness of said second plated magnetic layer.
