发明名称 Method for smoothing magnetic recording media
摘要 A smoothing method for a magnetic recording media eliminates a gravure pattern therein and a device therefor includes a belt like conveyer running together with a nonmagnetic sheet or tape at the same speed applied above a smoothing device. Many magnets are disposed underneath the conveyer to affect the magnetic field of the magnetic head applied to the magnetic recording solution to orient easily the magnetization axes of the magnetic particles of the magnetic recording solution. The magnets are positioned in various arrangement to increase the effect of the smoothing method. Also, a nonwoven fabric is used in place of the belt like conveyor to decrease friction and remove dust out of the magnetic recording media. Thus, the quality of the final products is much more highly improved than that of conventional products.
