Writing element with no return path

摘要

A writing element includes a writing pole, a conducting coil and an insulating material. The writing pole includes a pole tip and extends therefrom to a back gap region. The conducting coil includes coil segments positioned adjacent and transverse to the writing pole. The coil segments are adapted to produce magnetic signals that orient magnetization vectors at the pole tip of the writing pole in a desired direction. The insulating material is formed between the writing pole and the coil segments. Magnetic signals do not conduct to the back gap region through a return pole element.
