Magnetic head and data recording and reproduction device

摘要

A magnetic head includes a coil for generating a magnetic field, and an electroconductive film superposed over the coil in the axial direction of the coil. The film is formed with a hole in the center. The electroconductive film is composed of a non-magnetic substance, and a first slit is formed in the electroconductive film extending from the hole to the outer peripheral edge of the electroconductive film. A second slit surrounds the inner peripheral edge of the electroconductive film. A continuity component is formed to electrically connect the inner peripheral edge of the electroconductive film to a radially outer region of the electroconductive film.
