摘要：

The recording field of a narrow-track single-pole (SPT) write head with a double-layered medium was investigated using 3-D eddy current transient finite element analysis. Results show a large head field strength reaching B, of head pole at track width of 100 nm and a high frequency response of 2 GHz. (C) 2001 Elsevier Science B.V. All rights reserved.
