A Low-flying Single Pole Head for Perpendicular Magnetic Recording
1997
Journal of the Magnetics Society of Japan
A thin film magnetic head for perpendicular recording was developed by the combination of a single pole transducer and a low flying slider. FeZrN sputtered film with high saturation magnetization was employed as a main pole of the transducer and the slider was designed from fluid dynamics calculation to achieve very low flying height. The read/write characteristic of the head at 25 nm flying height using CoCrlNiFeNb media were 350 n Vp-p/ J.L m' m/s' turn at 15 kFCI and -34dB in overwrite.
