Recording Field Analysis of a Planar Type Write Head
Details
High-density longitudinal magnetic recording write heads are investigated by using transient finite element analysis. First, conventional write heads are analyzed and the issue is discussed. Then, a planar type write head is mentioned and the possibility(large recording field strength)and the issue(large cross-track field)are noted. Finally, the head structure optimization using the FEM are carried out and the planar head having large recording field and less cross-track field is obtained.
