Abstract
The present invention provides a device and a method for producing a magnetic recording medium having a lubricant membrane with a uniform thickness on a surface. The device for producing the magnetic recording medium includes: a hanger device that is inserted into the central hole of the magnetic recording medium and supports the magnetic recording medium in a hanging state; and a raising and lowering device that raises and lowers one of the hanging device and an immersion tank with respect to the other thereof. The hanger device includes a support plate of which an upper end comes into contact with an inner circumference of the magnetic recording medium and a liquid-cutting plate which extends from a lower end of the support plate and is distant by a space along the inner circumference of the magnetic recording medium from the inner circumference of the magnetic recording medium.
