Abstract
A multiple layered interconnect structure to provide an electrical interface between one or more electrical elements on a head to read/write circuitry is disclosed. The interconnect structure includes first and second interconnecting layers. The first interconnecting layer is formed on a slider body of the head and includes a first or lower bond pad connectable to one or more electrical elements on the slider body through the first interconnecting layer. The second interconnecting layer includes a second or upper bond pad connectable to the one or more transducer elements through the second interconnecting layer. The second interconnecting layer is on top of the first interconnecting layer and the structure includes an insulating layer between the first and second interconnecting layers. In illustrated embodiments, the first and second interconnecting layers are formed on a back side or surface of the slider body to form top side upper and lower bond pads that interface with bond pads on a flex circuit to provide the interface to R/W circuitry.
