发明名称 VERTICAL MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING/REPRODUCING DEVICE
摘要 Provided is a method for easily manufacturing a low cost ECC type magnetic recording medium which is easily designed. A magnetic recording/reproducing device is also provided. In a vertical magnetic recording medium, at least a soft magnetic lining layer, a base layer, an intermediate layer and a vertical magnetic recording layer are arranged on a nonmagnetic substrate. The magnetic recording layer is composed of at least one main recording layer and an auxiliary recording layer. The main recording layer is composed of a layer having vertical magnetic anisotropy. The auxiliary recording layer is a multilayer film which has three or more layers and is configured by alternate lamination of soft magnetic layers and nonmagnetic layers, and the outermost layer to a nonmagnetic substrate is the soft magnetic layer.
