发明名称 Structure for current perpendicular to plane giant magnetoresistive read heads
摘要 A recording head for use with magnetic recording media includes a current perpendicular to plane (CPP) type giant magnetoresistive (GMR) read element, with the alternating magnetic and nonmagnetic layers within the GMR read element either perpendicular or angled to the read head's shields. This structure maximizes the number of alternating layers within the GMR read element, and minimizes the area available for flow of the test current. Both total resistance of the GMR element, and the change in resistance as a function of changes in magnetic flux, relative to total resistance, are thereby increased. The sensitivity of the GMR read element is thereby increased, permitting storage of information within magnetic recording media at greater densities. The invention also includes a method of manufacturing a read head using such a GMR element.
