Abstract
The present invention is a method and apparatus for providing an electrical substrate. The electrical substrate comprises a dielectric layer; and a first conductive layer attached to the dielectric layer, in which the first conductive layer has an elliptical cross-section. The electrical substrate may be used in a flexible circuit that connects the read/write head to electronic circuitry in a hard disk drive.
Claims11
