The read/write performance of a single pole type head was greatly advanced by increasing the magnetic circuit efficiency. These developments have enabled recording densities of 530 Mb/in2 without MR and PRML technology. In order to achieve higher recording density, we have investigated CoZrNb films deposited by ion beam sputtering. It is confirmed that an increase of the amount of incident particles with a large incident angle leads to improve the magnetic properties of CoZrNb films in the thickness range less than 2000 Å.
