摘要： A vertical recording type magnetic recording medium which includes at least a vertical magnetic recording layer and a backing layer which backs the vertical magnetic recording layer and is magnetized in a direction toward the inside of the surface. The backing layer is made of ferromagnetic materia1 which has a compensation temperature in the neighborhood of a recording/reproducing temperature at which magnetic information, recorded in the vertica1 magnetic recording layer, is reproduced.

摘要： A perpendicular magnetic recording medium at least comprises a perpendicular magnetic recording layer and a backing layer backing the perpendicular magnetic recording layer. The backing layer has an in-plane magnetization and is formed of a ferrimagnetic material having a compensation temperature in the vicinity of a recording/reproducing temperature in which reproducing of magnetic information is made from the perpendicular magnetic recording layer.
