The writer further includes a shield extending along and about parallel to only a portion of the trailing edge or only a portion of the first side edge, and the shield does not extend along the second side edge. In addition, an angle formed between the first side edge and the trailing edge along an air bearing surface side of the writer is different than an angle formed between the second side edge and the trailing edge along the air bearing surface side of the writer. Other systems are also presented which include advanced shingled writing head designs.
