Abstract
A method for preparing a magnetic recording medium includes the following steps of providing a substrate; providing a solution consisting essentially of ions of cobalt, manganese and iron in deionized water; and preheating the substrate and spraying the solution onto the preheated substrate at an elevated temperature to uniformly distribute droplets thereon and form a magnetic recording medium film on the subtrate. Such method can prepare a magnetic thin film which has a high recording density and is cost-effective.
