Abstract

PURPOSE:To simplify the production process and to reduce the cost by disposing a porous body which applies a lubricant on a magnetic layer of a metallic thin film type by coming into contact with the layer within a vacuum chamber. CONSTITUTION:The first vacuum chamber 1a is used for forming the magnetic layer consisting of a magnetic thin film and the application of the lubricant on the magnetic layer is executed in the second vacuum chamber 1b. The first vacuum chamber 1a and the second vacuum chamber 1b are connected via a connecting passage 1c. A substrate 8 on which a magnetic thin film is formed in the first vacuum chamber 1a and which is introduced to the second vacuum chamber 1b, is brought into contact with a can roll 9 along therewith. The porous body 10 is in elastic contact with the can roll 9 and since a lubricant soln. in a tank 11 is stored in the porous body 10, the lubricant soln. is applied on the surface of the magnetic thin film of the substrate 8 as the substance 8 travels. Since the application is executed in the second vacuum chamber 1b, magnetic metals are not deposited thereon at the time of the application and the vacuum degree conditions in the first vacuum chamber 1a are hardly received. The formation of the magnetic thin film and the application of the lubricant are independently and continuously executed and, therefore, the respective operations are well carried out and the cost is reduced by the simplification of the production processes.

BACKGROUND OF THE INVENTION In a magnetic recording medium such as a magnetic tape, due to a demand for high density recording, a binder resin is not used as a magnetic layer provided on a non-magnetic support, instead of a coating type using a binder resin. A metal thin film type that is not used has been proposed. That is, it is well known that a magnetic recording medium having a magnetic layer formed by a dry plating means such as vacuum deposition, sputtering or ion plating has been proposed. Since the magnetic recording medium of this type has a high packing density of magnetic material, it is suitable for high-density recording.

DISCLOSURE OF THE INVENTION However, in the above-described lubricant applying means, the magnetic layer is formed in the vacuum chamber, while the lubricant is applied in the atmosphere.

As a result, we have reached the revelation that the manufacturing process can be simplified and the cost can be reduced.

The porous body 10 is elastically contacted with the can roll 9, and the lubricant solution in the tank 11 is supplied to the porous body 10. Therefore, the lubricant solution is supported as the support 8 runs. It is applied on the surface of the magnetic thin film (surface of the oxide film) of the body 8 so that the thickness after drying is about 20Å. In addition, this application is performed in the second vacuum chamber 1
Since it is carried out in b, the magnetic metal does not deposit at the time of application, and the conditions such as the degree of vacuum in the first vacuum chamber 1a are not easily changed by the solvent that evaporates and the formation and lubrication of the magnetic thin film. Since the application of the agent is performed independently,
Each is done well. After this lubricant application process,
A smoothing process is performed by the smoother 12, a drying process is performed by an infrared lamp, and then the film is taken up by a take-up roll 7b.
