Abstract
The narrow-track single-pole (SPT) write head recording field was investigated using 3-D eddy current transient finite element analysis. After validating the finite element model for the SPT head with a double-layered medium, head field time variations were studied for various cases. Results show that a large head field strength reaching B s of head pole at track width of 100 nm and high frequency response of 2 GHz.
