Abstract
A support means is disclosed for mounting an integrated circuit chip preamplifier with respect to an aluminum transducing head support arm in a magnetic disc drive. The support means includes two heat shields, each with an aluminum foil layer facing the preamplifier and a thermally insulative adhesive layer facing the rigid arm. The preamplifier is secured to the foil layer of the most adjacent heat shield with an electrically insulative but thermally conductive adhesive. The alternating thermally conductive and thermally insulative layers interfere with longitudinal heat transfer but allow lateral heat transfer to promote heat dissipation laterally outwardly of the support means, and thus substantially reduce thermal expansion of the support arm.
