Multi-parameter optimization of write head performance using adaptive response surface

A method for optimizing performance of a magnetic write head, comprising:

• constructing a table of data points based on three parameters of a write head;
• performing a first set of testing of the write head based on data from the first table of data points, the testing providing first set of test results;
• constructing a first three dimensional response surface based on the first set of test results;
• using the three dimensional response surface to determine a projected optimal design point;
• performing a second set of testing using the projected optimal design point, the second set of testing providing a second set of test results;
• and
• determining a convergence based on the difference between the first and second sets of test results.

A method for optimizing parameters of a magnetic write head, comprising:

• setting i=1;
• (step 1) constructing a table of data points for a plurality of parameters of a write head, and determining an experimentally determined optimal design point, and setting this experimentally determined optimal design point as the most current design point;
• (step 2) performing a i(th) testing and measurement of the plurality of parameters of the write head using the most current design point, the i(th) testing producing an i(th) result;
• (step 3) constructing an i(th) multidimensional response surface based on the results of the i(th) testing and measurement;
• (step 4) determining an i(th) projected optimal design point on this surface, and setting this i(th) projected optimal design point as the most current design point;
• (step 5) performing an i(th)+1 testing and measurement of the plurality of parameters of the write head using the i(th) design point, the i(th)+1 set of testing producing an i(th)+1 result;
• (step 6) determining a convergence based on a difference between the i(th) and i(th)+1 test result;
• and
• if the convergence exceeds a predetermined threshold, then setting i=i+1, and reiterating steps 1-6.
