ABSTRACT:
A magnetoresistive (MR) head having a double self-aligned contiguous junction includes an MR sensor structure with a biased guide joined thereto. The guide is formed using a first resist mask applied over the MR sensor structure. A guide biasing structure is formed using the first resist mask and a second resist mask applied over the first resist mask and the guide. The first resist mask is configured to form a double self-aligned contiguous junction between the MR sensor structure and the guide and guide bias structure. In this manner, the position of the guide biasing structure is carefully controlled so that it does not overlap the MR sensor structure.
