Abstract: The present disclosure generally relates to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a first write head and a second write head each coupled to a first pad and a second pad of a slider pad and an electrical circuit coupled to the first and second pads. The first write head is a wide writing write head, and the second write head a narrow writing write head. The electrical circuit comprises a first sub-circuit and a second sub-circuit connected in parallel, The first sub-circuit comprises a capacitor and a connection to a first thermal fly height control (TFC) of the first write head. The second sub-circuit comprises an inductor and a connection to a second TFC of the second write head. The electrical circuit is further connected to a third TFC of a read head, the second write head comprising the read head.
