ABSTRACT:
A recording element for use in a high density thin film recording head, and a method for manufacturing such an element are provided. The recording element includes a substrate, an insulative layer in contact with the substrate, and a first magnetic pole in contact with the insulative layer. The recording element also includes a coil tap in contact with the insulative layer, where the first magnetic pole and the coil center tap fabricated from the same material layer deposited on the insulative layer, and a coil having a lead deposited on the coil tap such that the coil tap is capable of conducting an electric current to the coil. The method for manufacturing the recording element includes depositing an insulative layer on a substrate and depositing a layer of magnetic and electrically conductive material on the insulative layer. The method also includes forming a first magnetic pole from the magnetic and electrically conductive layer, forming a coil tap from the magnetic and electrically conducting layer, and depositing a coil having a lead on the coil tap such that the coil tap is capable of conducting an electric current to the coil.
