A method of fabrication of the write head of a perpendicular recording head allows for production of P3 pole tips of width less than 200 nm. Expertise of highly trained analysts is employed in a time-efficient manner to write discrete parameterized configuration script templates for maximum re-use, thereby reducing the number of scripts that they are required to maintain and deploy with each update. The cathode side seal member is provided outside the membrane electrode assembly. The closure comprises a cap having an opening, the opening capable of communicating with the mouth of a container. The software control mechanism is structured to control a function of a presently interfaced media application on the display screen.
