Abstract:
A magnetic head with an inductive head type recording head used in recording onto a magnetic medium, comprising:an inductive head type recording head of a structure as being provided with a magneto-gap layer of non-magnetic and non-conductive material between a first magnetic core and a second magnetic core, and an exciting coil electrically isolated from said first magnetic core and said second magnetic core, wherein a part of magnetic flux from magnetic cores excited by said exciting coil leaking from said magneto-gap layer, and recording onto said magnetic medium being conducted by said leaking flux; wherein said second core is a laminated type magnetic core comprising laminated three kinds of layers of a first magnetic layer allocated most adjacently to said magneto-gap layer, a second magnetic layer laminated on said first magnetic layer, and a third magnetic layer formed to be a desired shape on said second magnetic layer by frame plating, and as said second magnetic layer, a magnetic material which substantially does not melt while plating of said third magnetic layer is conducted is selected.
