A system for poling piezoelectric devices comprises a plurality of thin-film components, a plurality of piezoelectric devices, a poling pad for poling the piezoelectric devices, a plurality of traces, and a plurality of current-limiting elements. The thin-film components are separated by dice lanes to form an array, and the piezoelectric devices are formed on the thin-film components. The traces connect the piezoelectric devices across the dice lanes in parallel to the poling pad. Each current-limiting element is connected in series with one of the piezoelectric devices, in order to limit current to individual piezoelectric devices that experience current-related failure.

A magnetic writer has at least a write pole with a first partial side shield and a second partial side shield. The write pole has a leading edge and a trailing edge along an air bearing surface (ABS) and a first side and a second side along an axis orthogonal to the ABS. The first partial side shield is separated from the first side of the write pole and extends from adjacent the write pole from the trailing edge to a location intermediate that trailing edge and the leading edge.
