The present invention relates to the method of optimizing of planar type write heads for ultra high density magnetic recording. More particularly, the invention relates to a planar type write head for an ultra high density drive which can record information on a medium with high magneto-crystalline anisotropy. One of the most serious problems for high density recording is thermal fluctuation and this problem can be solved by using a medium with high magneto-crystalline anisotropy. However, this requires a write head capable of generating a high write field According to the present invention, the method of optimizing a planar type write head for ultra high density magnetic recording comprises the step of optimizing the characteristics of the write head by changing the shape parameters of the write head using the first, second a0nd third type shape control methods.
A method of optimizing the design of a planar type write head for achieving ultra high density magnetic recording using a medium with high magneto-crystalline anisotropy, wherein the design of said write head are optimized by changing the shape parameters of said write head using the first, second and third type shape control methods that take certain parts of said write head as the shape and size of a, b, and c.
