Abstract

PURPOSE:To obtain a uniform and smooth magnetic film by previously providing a base material with an edge as high as the thickness of magnetic film, and flowing a magnetic paint onto said edge. CONSTITUTION:On a nonmagnetic base 1, edge parts 2 as high as the thickness of a necessary magnetic film are formed and a magnetic paint 3 is applied over the coated surface between the edges 2 and is moved while pressed against the edge parts 2 with a squeezer 4 to form a smooth magnetic paint layer as high as the edge parts 2. Then, the layer is dried and cured.

It needs to be extremely thick and smooth. Conventional methods for forming a magnetic film include spinner and printing methods, but since the thickness that can be coated in the first coat is directly *opH, multiple coats are required to obtain a tenth layer Z'j4. When layered in this way, it was not possible to apply it smoothly, and mass production was not possible due to many problems such as a polished finish and contamination due to the length of each coat.

本発明の目的は、磁気ディスクや磁気ドラム等の基材に
均一で平滑な磁性膜を、必要とする膜厚に容易に形成で
きる磁気記録体の製造方法を提供することにある。An object of the present invention is to provide a method for manufacturing a magnetic recording medium that can easily form a uniform and smooth magnetic film to a required thickness on a base material such as a magnetic disk or a magnetic drum.

。According to the present invention, an edge of the height of the magnetic film is attached to the magnetic base material in advance, the magnetic Ik material is poured into this edge, and the excess magnetic paint is scraped off with a squeegee or roller. The purpose can be achieved by sintering it after taking it.

以下、本発明を磁気ディスクに適用した実施例について
第１図、第２図により説明する。An embodiment in which the present invention is applied to a magnetic disk will be described below with reference to FIGS. 1 and 2.

装置により、磁性膜に磁気記録を行なって完成する。Figure 1 is a cross-sectional view of the base material of a magnetic disk, and Figure 112 shows that the base material is magnetic! FIG. 3 is an explanatory diagram showing a state in which the Ii material is applied. In the figure, 1 is a disk as a non-magnetic base material made of aluminum, brass, etc., and 2 is an edge formed on the die 1 at a height corresponding to the required magnetic film thickness. After cleaning this disk 1, apply magnetic paint 3 on the coated surface between the edges 2, and
is moved as shown in FIG. 2 while pressing against the edge 2 with a squeegee 4 having a diameter larger than that of the squeegee 4. By doing this, it is possible to form the magnetic paint smoothly by the height of the edge 2. Thereafter, this paint is dried and baked to form a magnetic film.Finally, a magnetizing device performs magnetic recording on the magnetic film to complete the process.

向上の効果がある。In this way, the coating film is formed by applying magnetic paint on the base material at the edge corresponding to the thickness of the magnetic film, and using a squeegee or roller to remove excess magnetic paint that exceeds the height of the edge. For example, the desired film thickness and smoothness can be obtained with one application.
Mass production is also possible, and since Sakuto is no longer a harmful bird, it has the effect of improving reliability.
