ABSTRACT:
A magnetic head comprises a first magnetic core having a first gap on an exposed surface side; a second magnetic core having a second gap on an exposed surface side forming an identical surface with an exposed surface of the first magnetic core, and disposed in the vicinity of the first magnetic core; and a magnetic film disposed in the vicinity of the second magnetic core and for magnetically short-circuiting a magnetic circuit of the second magnetic core without passing through a coil wound around the second magnetic core. The magnetic film prevents crosstalk to the first magnetic core from the second magnetic core.
