MAGNETIC RECORDING MEDIUM, METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING DEVICE

To provide a magnetic recording medium capable of containing magnetic particles having a fine crystal gain size in a surface layer of a magnetic recording layer and in the vicinity thereof.SOLUTION: A magnetic recording medium according to the present invention includes a substrate and a magnetic recording layer containing magnetic particles having a L10 structure. The magnetic recording layer is (001) oriented, the growth surface of the magnetic recording layer has a (001) surface, a (111) surface, and the equivalent surfaces thereof, and the area ratio (((111) surface + (111) equivalent surface)/((001) surface + (111) surface + (111) equivalent surface))) of the (111) surface and its equivalent surface in the growth surface is 0.2 to 0.7.SELECTED DRAWING: Figure 4 【課題】磁気記録層の表層及びその近傍に微細な結晶粒径を有する磁性粒子を含むことができる磁気記録媒体を提供する。【解決手段】本発明に係る磁気記録媒体は、基板と、Ｌ１０構造を有する磁性粒子を含む磁気記録層と、を備え、前記磁気記録層は、（００１）配向し、前記磁気記録層の成長面は、（００１）面と、（１１１）面及びその等価面を有し、前記成長面における（１１１）面及びその等価面の面積比率（（（１１１）面＋（１１１）等価面）／（（００１）面＋（１１１）面＋（１１１）等価面）））が、０．２～０．７である。【選択図】図４
