Abstract:
1. A slider for magnetic recording comprising: a slider body; a magnetoresistive read sensor formed on the slider body; an inductive write head formed on the slider body; an electrical element; formed on the slider body; first and second contact pads; first and second leads connecting the magnetoresistive sensor with the first and second contact pads; third and fourth contact pads; third and forth leads connecting the inductive write element with the third and fourth contact pads; fifth and sixth contact pads; and fifth and sixth leads connecting the electrical element with the fifth and sixth contact pads; and wherein at least one of the first and second leads crosses at least one of the fifth and sixth leads at an angle of between 45 and 135 degrees, the at least one lead being separated from the at least one fifth and sixth lead by a dielectric material; wherein the inductive write head further comprises a first magnetic pole, a second magnetic pole and a magnetic pedestal magnetically connected with the first magnetic pole, and wherein the electrical heater element is formed beneath and aligned with the magnetic pedestal portion, and further comprising a thermally conductive Cu layer formed beneath the electrical heater for conducting heat away from the write head.
