Abstract
The magnetic head comprises two magnetoresistance effect elements and a soft magnetic film connecting end portions of the magnetoresistance effect elements with each other. The two magnetoresistance effect elements and the soft magnetic film are arranged in series so as to form a single magnetic circuit, and a magnetic gap is provided in the side of a surface facing a magnetic medium. Magnetic flux from the magnetic medium is introduced into the magnetoresistance effect elements through the magnetic gap. An insulating material may be used to fill the magnetic gap.
