Abstract

See full text

A method for optimizing design parameters of a magnetic write head. The method involves compiling a table of data points for a plurality of design parameters. An experimentally derived optimal design point is determined a first set of tests are performed at this experimentally determined design point. A three dimensional response surface is generated based on the testing. Then, a projected optimal design point is determined from the three dimensional response surface. Another test is performed using this projected optimal design point, and a convergence is determined by comparing the results of the first and second tests. If the convergence is within a predetermined value, then the process is complete. If the convergence is not within the predetermined value, then the process is repeated using the most recent projected optimal design point.
