Provided is a magnetic head having a magnetic thin film structure that reduces the effect of a stray field and generates a magnetization reversal at a high speed. The magnetic head includes a first pole, a second pole spaced apart from the first pole, and an induction coil that induces a magnetic field in the first and second poles, wherein the first and second poles include a pole tip in which a leakage flux for recording is generated, and a head yoke that guides the flux flowing in the poles, and at least one implant for controlling a magnetic domain, the implant formed in at least one of the first and second poles. The magnetic thin film can effectively reduce the effect of a stray field entering from the outside, and can control a domain wall motion so that high speed magnetic recording is possible, by generating a magnetization reversal at a high speed corresponding to a magnetic field applied by an induction coil.
