て、表面平滑度を両面均一にする技術が必要であった。Conventional technology The conventional method for manufacturing this type of smooth coating film is as shown in Figure 2 (e.g., Comprehensive collection of practical information on f-dispersion technology and industrial applications, p. 762, Management Development Center Publishing Department). Ta. That is, after dust removal, a magnetic paint prepared by mixing and dispersing magnetic powder and vehicle is applied onto the paste, oriented in a magnetic field, and after drying, surface treatment is performed. In the case of double-sided coating, after the surface treatment of one side is completed, magnetic paint is applied to the remaining side, and a dry surface treatment is performed. From the point of view of surface treatment, this means that each side is treated twice. Therefore, a technique was needed to make the surface smoothness uniform on both sides.

するという問題点を有していた。Problems to be Solved by the Invention However, in the above method, when magnetic recording media are continuously produced, the magnetic layer may adhere to the surface treatment roll, and the surface treatment roll may generate heat due to continuous production. ,
The roll warps in the longitudinal direction, causing uneven surface treatment.
As a result, the product characteristics fluctuate, which poses a problem in production. Further, although the above description relates to one side, there is a problem in that defects occur even more when both sides are coated.

ある。Means for Solving the Problems In order to achieve the above object, the present invention provides a coating film formed on the top of a smooth first sheet whose surface has been subjected to a mold release treatment, in which the coating surface is coated with an adhesive. The second sheet with the coating film transferred thereto, and the The third sheet was processed in the same way as the second sheet.
The non-coated surface of the first sheet is adhered with an adhesive, and one sheet is created from the second sheet and the third sheet.

Furthermore, by transferring on both sides, there is no influence from the other side.
実施例 以下、本発明の一実施例を図面にもとづいて説明する。Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

膜が可能となるものである。In FIG. 1, reference numeral 1 denotes a smooth sheet whose surface has been subjected to mold release treatment, and a coating film 2 is formed on the surface of the smooth sheet 10. 3 is a sheet on which the coating film 2 is formed. Reference numeral 4 denotes an adhesive supply unit that joins the sheet 3 and the coating film 2, and as the sheet 3 moves, it gradually supplies adhesive to one side of the sheet 3, that is, the surface to be joined to the smooth sheet 1. 8 is also an adhesive supply unit, and the adhesive is applied to the other side of the sheet 3 having passed through the pressure roll unit 6 to form a smooth portion on one side, and the other sheet 3 having a smooth portion on one side is coated with adhesive.
Two pressure rolls 7 having parallel axes and in contact with the non-coated surface of
A sheet 8 having smooth coating films on both sides is formed. Since the coating film on the sheet 8 is a direct transfer of the flat surface of the smooth sheet 1, the smoothness is significantly improved compared to the case where the sheet 3 is smoothed by applying paint. In addition, the control of the thickness of the coating film is easier than when directly applying the coating, and a concrete button allows a thin film of 0.5 μm to 5 μm.
