Head/pre-amp ribbon interconnect for data storage devices

摘要

In a data storage device, a ribbon interconnect is provided for electrically connecting a read/write head to an electrical circuit component. The read/write head is defined by separate read and write transducer elements. The interconnect comprises at least one carrying medium; and at least three conductors captured by the carrying medium in a coplanar arrangement. The at least three conductors define asymmetrical pitches. Each pair of the at least three conductors define a predetermined complex impedance. The individual complex impedances are not equal. The carrying medium may be a polymeric film. The at least three conductors are substantially cylindrically shaped and may be adhesively captured by said carrying medium. The ribbon interconnect may include at least one conductive ground plane. An insulation material may be disposed about each of the at least three conductors.
