Abstract:
A magnetic recording head with an overall planar design and tight dimensional control of throat height and notch width is achieved below the gap. Writer poles include very high magnetic moment material on both sides of the writer gap. Additionally the pole tips are shaped to provide high field with good spatial gradient for optimal writing conditions, thereby extending the capability of longitudinal recording heads for high density and high frequency applications.
