1. A contact magnetic transfer template comprising:
a flexible plastic film having first and second opposite surfaces, the first surface containing islands of soft magnetic material and nonmagnetic regions, the upper surfaces of the islands and nonmagnetic regions forming a continuous substantially planar surface;
a rigid silicon support, wherein only the perimeter of the plastic film is attached to the silicon support; and
a barrier layer on the second surface of the plastic film and formed of a material resistant to a wet etchant capable of etching silicon, the perimeter of the barrier layer being between the silicon support and the plastic film.
