Low inductance double-sided Metal-In-Gap nano composite slider using Fe-Ta-N magnetic film system for 250 Mb/in/sup 2/ recording

We studied some characteristics of a double-sided Metal-In-Gap (DMIG) nano composite slider that has a low inductance structure, Fe-Ta-N type of magnetic film and new geometrical configuration of the gap area. The inductance of this head is approximately 1.0 nH/T/sup 2/. The electrical performance of this head has been evaluated with 5.5 /spl mu/m Track Width and 0.25 /spl mu/m Gap Length for 1800 Oe media. O/W is less than -34 dB at 53 kFCI. Output voltage is more than 150 nVp-p/(um.m/s.turns) at 53 kFCI. This performance is seen to be promising for 250 Mb/in/sup 2/ recording.<
