Abstract
The invention is a magnetoresistive recording head including the reader portion that has a top and bottom shield, a first auxiliary electrical connection, a second auxiliary electrical connection, a first auxiliary electrical contact, and a second auxiliary electrical contact, where the first auxiliary electrical connection electrically connects the first auxiliary electrical contact to the top shield, and where the second auxiliary electrical connection electrically connects the second auxiliary electrical contact to the bottom shield. There is also provided a method of determining the electrical integrity of a magnetoresistive recording head that includes fabricating a magnetoresistive recording head including a reader portion having at least one shield, at least one reader contact, that is electrically connected to the reader portion, a shield shunt, at least one auxiliary electrical connection, and at least one auxiliary electrical contact that is electrically connected to at least one of the shields, and measuring the integrity of the magnetoresistive recording head.
