The properties of write heads with the pole tip consisting of the FeCoAlO films were presented. The writing properties of the write head were measured by using media with a coercivity of 3200 Oe. The overwrite (O/W) improvement of about -5dB was obtained when the pole tip was changed from Bs∼1.8 T material to Bs∼2.2 T FeCoAlO material.
