Abstract:
A method of making a magnetic head that has an air bearing surface (ABS) comprising:forming a first shield layer;forming a first gap layer on the first shield layer;depositing a read sensor material layer on the first gap layer;removing first and second portions of the read sensor material layer at first and second lead layer sites that are recessed from an ABS site;depositing first and second low resistance lead layers at the first and second lead layer sites;removing an additional portion of the read sensor material layer to form a back edge and stripe height of an MR read sensor site that is recessed from the ABS site;removing further first and second portions of the read sensor material at first and second high resistance lead layer sites and adjacent first and second side edges of the read sensor site to define a track width of the read head;depositing first and second high resistance lead layers at the first and second high resistance lead layer sites that abut the first and second side edges and cover at least a portion of the first and second low resistance lead layers respectively;forming a second gap layer on the read sensor site and the first and second high and low resistance lead layers; andforming a second shield layer on the second gap layer.
