Abstract

The head field distribution for hard/soft magnetic composite pillar array media (CPA media) is significantly different from that of the conventional patterned media. The head field distribution for a CPA media-single-pole-type (SPT) head system which assumes 1 Tbits/in2 recording is calculated by the three dimensional finite elements method. One of the features of the system is that a magnetic flux concentrates in a hard magnetic unit. The system is found to yield 80% of the field strength of SPT head and continuous SUL media system.
