Writing performance of IND/SV combination heads with sub-micron track width

For the write heads, good OW and high frequency performance with submicron track width are necessary conditions to achieve over 10 Gbpsi recording density. For these purpose, the new structure write head combined SV read head has been developed. The pole tip and yoke are individually patterned and stitched. In addition to that, the yoke length was reduced by shortening the coil pitch. The writing performance was compared with the conventional structure
