MAGNETIC HEAD FOR READING AND/OR WRITING DATA FROM AND/OR TO A MAGNETIC MEDIUM

摘要

A magnetic head for reading and/or writing data from and/or onto magnetic media comprises a core (11 min ) of ferromagnetic material, the core having a C-shaped portion (14 min ) and an I-shaped portion (12 min ) joined thereto. The C-shaped portion and I-shaped portion have confronting surfaces forming a gap (20 min ) therebetween. A coil (24 min ) induces magnetic flux in the core (11 min ). A first layer (22 min ) of magnetic material has a magnetic permeability greater than the ferromagnetic material of the confronting surface of the C-shaped portion forming the gap. An interface between the C-shaped portion and the first layer is substantially parallel to the gap. A second layer (42) of the magnetic material is deposited on an additional surface of the core. This second layer is integral with the first layer and overlaps the interface.
