Zig-zag MIMO head reducing space between three sensors

摘要

The embodiments disclosed generally relate to a magnetic recording head having three magnetoresistive effect elements. The structure comprises a first magnetoresistive effect element on a lower magnetic shield layer. Additionally, two lower electrodes are disposed on the two sides of the first magnetoresistive effect element. A second magnetoresistive effect element is disposed on a lower electrode while a third magnetoresistive effect element on another lower electrode. An upper magnetic shield layer is disposed between the second magnetoresistive effect element and the third magnetoresistive effect element. The upper magnetic shield also serves as an electrode of the first magnetoresistive effect element.
