ABSTRACT:
To manufacture a magnetic recording medium with reduced coating defects by effectively and reliably removing foreign matter that causes coating striations.
In a manufacturing method for a magnetic recording medium that includes a process in which a magnetic layer is formed on a flexible support, the aforementioned magnetic layer is formed after cleaning the aforementioned flexible support by bringing it into contact with a rotating cleaning roll, the contact surface of which consists of at least an adhesive substance or with a cleaning member, the contact surface of which consists of at least a porous polymer and so providing a manufacturing method for a magnetic recording medium in which foreign matter, which causes coating striations, can be efficiently and reliably removed and in which it is possible to manufacture a magnetic recording medium with reduced coating defects.
