    摘要： A perpendicular magnetic recording layer may include a hard granular layer, an exchange break layer formed on the hard granular layer, and a soft granular layer formed on the exchange break layer. In some embodiments, the exchange break layer may consist essentially of ruthenium. In some embodiments, the perpendicular magnetic recording layer may include n magnetic layers and n−1 exchange break layers, where n is greater than or equal to three, and where the n−1 exchange break layers alternate with the n magnetic layers in the magnetic recording layer.

    摘要： A perpendicular magnetic recording medium comprises a non-magnetic substrate having a surface; and a plurality of overlying thin film layers forming a layer stack on the substrate surface, the layer stack including a magnetically hard perpendicular magnetic recording layer structure and an underlying soft magnetic underlayer (SUL), the SUL having a thickness of up to about 100 Å. Also disclosed is a data/information recording, storage, and retrieval system comprising the perpendicular magnetic recording medium and a single-pole magnetic transducer head including main and auxiliary poles positioned in spaced adjacency to an upper surface of the layer stack, the single-pole transducer head comprising a front shield adjacent the main pole.
