ABSTRACT:
A flexible circuit assembly to provide communication to and from data transducer heads located on a load beam of a suspension assembly of a disk drive. Two discrete preamplifier integrated circuits, one of which has a pin-out that is a mirror image of the other, are mounted on a flexible circuit substrate such that the mirror image preamplifier integrated circuit mounted thereon folds underneath the first preamplifier integrated circuit. A head-arm access strip of the flexible circuit is installed in a distorted S-shaped bow in order to reduce the force on the suspension assembly.
