Abstract of the Disclosure Magnetic recording elements which contain at least two magnetic recording layers on the same side of a support and processes for preparing these elements are disclosed. The layer interfaces formed by magnetic recording layers within these elements are substantially free of irregularities which give rise to an objectionable modulation modulation level. This results in elements exhibiting significantly improved recording properties. The elements can be prepared by applying at least two magnetic recording layers to the same side of a non-magnetizable support while these layers are in the liquid state and then solidifying the layers. A particularly advantageous coating method is disclosed in which a single slide hopper, as illustrated in fig. 3, is employed to simultaneously cost magnetic recording layers on a non-magnetizable support. -1-
