An MR head (50) includes an MR film (34) electrically connected to two lead layers (56,58) that are asymmetric with respect to at least one of thickness and resistance. In a preferred embodiment of the present invention, the MR head includes a write pole (68) that extends over a thinner lead layer (56) and that terminates over the MR film (34) so that the write pole does not extend over a thicker lead layer. In another preferred embodiment of the present invention, a thinner lead layer is connected to a single-ended preamplification circuit (92), and a thicker lead layer is connected to a ground or reference voltage. <IMAGE> |
