Abstract:
A magnetic head that has a head surface for facing a magnetic medium, comprising:a read sensor bounded by the head surface, first and second side edges and a back edge; first and second leads wherein each lead has a high resistance lead layer and a low resistance lead layer; first and second gap layers; the read sensor and the first and second leads being sandwiched between the first and second gap layers; each high resistance lead layer of said first and second leads being partially bounded by the head surface and first and second side edges and each low resistance lead layer of said first and second leads being partially bounded by a front edge, which is recessed from the head surface, and first and second side edges; the first side edge of the high resistance lead layer of each of the first and second leads being in contact with the first and second side edges respectively of the read sensor and electrically connected thereto; substantially all of each of said high resistance lead layers located between the head surface and said back edge of the sensor extending in a direction perpendicular to the head surface and making electrical contact in a respective contact region beyond said back edge with a respective low resistance lead layer; for each of the first and second leads, the high resistance lead layer being located between the first gap layer and the low resistance lead layer in said respective contact region; and the first low resistance lead layer being located entirely on the first high resistance lead layer and the second low resistance lead layer being located entirely on the second high resistance lead layer.
