Research Abstract

The representative researcher investigated and proposed recording write heads in perpendicular magnetic recording system in the next generation : two-dimensional magnetic recording with shingle writing, thermally-assisted magnetic recording, microwave-assisted magnetic recording and bit-patterned magnetic recording. The shielded planar heads are superior to conventional heads with regard to obtaining a faster response and a larger recording field, and even a smaller adjacent track erasure(ATE) field.
