Abstract
An assembly comprises a magnetoresistive element (16), a thermally conductive member or magnetic film (18, 26), and a film of thermally conductive, high electrical resistivity amorphous diamond-like carbon (14, 22) sandwiched between the magnetoresistive element and the thermally conductive member. In an MR head (12), at least one of the half-gaps of the MR head is fabricated of the amorphous diamond-like carbon film to dissipate heat from the MR element to the thermally conductive magnetic film(s) and shield the MR element from the magnetic film(s).
