Abstract
A miniature signal booster element is inserted into the conductive path along a pair of wires leading between the slider end of a flexure member in a disk drive and the mounting end of the flexure. The signal booster element comprises an integrated circuit amplifier or a ferrite core transformer. The ferrite core transformer may comprise two separate coils: one coupled to the transducer and the other coupled to the output side of the wire pair; or a single coil with an intermediate tap connection. The signal booster element is single coil with an intermediate tap connection. The signal booster element is encapsulated within an electrically insulative sheath to provide electrical insulation and mechanical isolation of the signal booster element from the flexure member.
