The reproducing efficiency of a perpendicular magnetic recording head was investigated. To improve the reproducing efficiency, scaling down and designing the head structure with a closed magnetic circuit and a coil wounl close to the main-pole are very effective. We have designed and fabricated a main-pole driven type perpendicular head with a thin-film coil wound around the main-pole film in addition to the wire coil. The reproduced voltage per turn of the thin-film coil was confirmed to be double that of the wire coil, and the same reproduced voltage as that of the thin-film perpendicular head with double-sided return path core can be obtained when the two coils of this head are used in series.
