METHOD FOR PRODUCING AND DEVICE FOR PRODUCING MAGNETIC RECORDING MEDIUM

摘要

The present invention provides a device and a method for producing a magnetic recording medium, the device and method capable of forming a lubricant membrane with a uniform thickness on a surface of the magnetic recording medium. Specifically, the device for producing the magnetic recording medium according to the invention is a device that forms a lubricant membrane on the surface of the magnetic recording medium by immersing the magnetic recording medium into an immersion tank that has a liquid lubricant and then raising the magnetic recording medium from the immersion tank. 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 the 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.
