ABSTRACT:
A trace conductor array includes an electrically insulative support substrate and a plurality of electrical signal trace conductors formed along substantially parallel paths in a single layer on the substrate. The electrical signal trace conductors each have a plurality of spaced apart trace conductor segments. Passive electrical trace conductors are formed on the substrate in spaces between the spaced apart adjacent trace conductor segments, and are spaced apart and electrically isolated therefrom. The passive trace conductors generally follow a geometry of the spaced apart segments and thereby repel magnetic flux lines at higher frequencies and result in decoupling of the high frequency current-carrying conductor trace segments. A preferred application is for interconnecting a head and a preamplifier/drive circuit within a hard disk drive.
