A method for preparing a magnetic recording medium is disclosed. The method involves forming a thin magnetic layer on a polyester film by means of a vapor deposition or plating method, continually moving the film while maintaining it at a tension of 400 g/mm.sup.2 or less and contacting the moving film with a heating device at a temperature within the range of 70.degree. to 200.degree. C. for a period of time within the range of 0.1 to 30 seconds. The method provides a non-binder type magnetic recording medium having improved skew characteristics without formation of curls.
