A magnetic recording medium which is optimum for high-density recording in which not only orientation of magnetic particles to the direction of thickness of a magnetic layer can be performed effectively but the orientation is maintained, and a method for producing such a magnetic recording medium. The method includes the steps of multiply applying a lower layer containing inorganic powder and resin, an intermediate layer containing resin and an upper layer as a magnetic layer containing needle-shaped ferromagnetic powder onto a non-magnetic support in the condition where all the layers are wet, and drying and solidifying the layers while the ferromagnetic powder contained in the upper layer is oriented at a predetermined angle with respect to the direction of thickness of the intermediate layer. In an another embodiment, only two layers are applied to the support including a non-magnetic layer and a magnetic layer.
