EIGENFREQUENCY MEASURING METHOD FOR AIR FILM OF MAGNETIC HEAD

摘要

PROBLEM TO BE SOLVED: To measure eigenfrequency for an air film of a magnetic head regardless of a suspension type supporting the magnetic head.;SOLUTION: In an eigenfrequency measuring method for the air film of the magnetic head floating on its surface by spinning of a magnetic disk on which a lubricant layer is formed with a liquid lubricant agent being coated on an uppermost surface, when the magnetic head is floated, fluid distribution for the liquid lubricant agent formed on the lubricant layer is measured, and eigenfrequency 9, 10 for the magnetic head is extracted from the fluid distribution for this liquid lubricant agent.;COPYRIGHT: (C)2005,JPO&NCIPI
