Provided is a magnetic recording head including a return pole, a writing pole spaced by a predetermined distance from the return pole, an induction writing coil for inducing a magnetic field to be formed across the writing pole, and a plurality of shield layers formed on the writing pole. Accordingly, magnetic fields generated inside and outside the magnetic recording head are prevented from concentrating on the return pole, and information is effectively written on and erased from an information recording media.
