A low-inductance thin-film head (60) includes a flux barrier layer (52) of electrical conductive, non-magnetic material such as copper, gold and aluminum positioned on the head, wherein stray flux from the head is cut off by the flux barrier layer (52) to reduce the inductance of the head (60). Stray flux entering the barrier layer creates an eddy current in the layer which cuts off the stray flux paths of the head. The flux barrier layer (52) can be placed in various positions, including downstream or upstream of the head (60), or between the poles (14, 16), to improve the read or write performance of the head. |
