摘要 |
The embodiments disclosed generally relate to a read head sensor in a magnetic recording head. The read head sensor comprises side shields in addition to the upper and lower shields. The upper shield sensor is a multilayer structure with antiferromagnetic coupling. The side shield is a multilayer structure whereby a lower magnetic layer is separated from an upper magnetic layer. The upper magnetic layer is ferromagnetically coupled to a bottom layer of the upper shield. The bias direction of the read head sensor is antiparallel to the bottom layer of the upper shield. |
