摘要： The present invention forms non-magnetic particles in a acicular shape as dispersed in a dispersoid liquid, forms a lower non-magnetic layer by coating the above-mentioned dispersoid liquid on a continually transported non-magnetic supporting base, forms an upper magnetic layer by coating the above-mentioned magnetic coating liquid in dual layers either consecutively or at the same time while the lower layer is still in its wet state, and performs an orientation of the magnetic particles by exposing the particles to a magnetic field while the dual layers as thus formed are still in their undried state. The orientation effect is achieved by making the specific gravity of the non-magnetic particles equal to or greater than that of the magnetic particles. The orientation effect is further enhanced by making the particle size of the non-magnetic particles equal to or less than that of the magnetic particles as measured along the long axis of the magnetic particles.
摘要翻译：本发明通过将分散在分散质液体中的非磁性颗粒形成为针状，通过将上述分散液涂布在连续输送的非磁性支撑基体上形成下部非磁性层，在下层仍处于湿态的同时连续地或同时地将上述磁性涂布液涂布成双层，并且通过将粒子暴露于磁场而执行磁性粒子的取向，而双层作为这样形成的仍然处于未干燥的状态。取向效果是通过使非磁性颗粒的比重等于或大于磁性颗粒的比重来实现的。通过使非磁性颗粒的粒径等于或小于沿着磁性颗粒的长轴测量的磁性颗粒的颗粒尺寸，进一步增强取向效果。

摘要： 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.
