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 a 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 additional 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 of the MR read sensor site and that extend from the first and second side edges away from the ABS to form first and second recessed high resistance lead layer portions;depositing first and second low resistance lead layers on said recessed first and second high resistance lead layers portions;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.
