Abstract
A thin-film magnetic head has a magnetoresistive effect read head element. The magnetoresistive effect read head element includes a lower shield layer, an upper shield layer, and a magnetoresistive effect layer formed between the lower shield layer and the upper shield layer. The magnetoresistive effect read head element also includes a lower antiferromagnetic layer. The lower antiferromagnetic layer is contacted with the lower shield layer only at an edge area of the lower shield layer.
