【発明の詳細な説明】
[産業上の利用分野]
本発明は、磁気ディスク媒体の製造方法に関し、特に保
護膜の付与方法を改良した磁気ディスク媒体の製造方法
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a magnetic disk medium, and more particularly to a method of manufacturing a magnetic disk medium with an improved method of applying a protective film.
[従来の技術]
従来、磁気ディスク媒体の保護膜の付与方法としては、
スピンコード法が用いられている。スピンコード法は磁
気ディスク媒体を回転させ、保護膜の付与を行なう方法
である。[Prior Art] Conventionally, the method of applying a protective film to a magnetic disk medium is as follows:
A spin code method is used. The spin code method is a method in which a protective film is applied by rotating a magnetic disk medium.
[発明が解決しようとする課題]
上述した従来のスピンコード法による保護膜塗布では、
磁気ディスク媒体の外周端面に保護膜材料がまわり込み
不均一に付着する。端面に付着した保護膜材料は塗布後
はがれ、媒体面上に付着し磁気記録装置の耐久性を悪化
させる欠点がある。[Problems to be solved by the invention] In the above-mentioned conventional spin code method for applying a protective film,
The protective film material wraps around the outer peripheral end surface of the magnetic disk medium and adheres non-uniformly. The protective film material attached to the end face peels off after coating and adheres to the surface of the medium, which has the drawback of deteriorating the durability of the magnetic recording device.
口課題を解決するための手段]
本発明の磁気ディスク媒体の製造方法は、磁気ディスク
媒体に保護膜塗布機にて保護膜を付与した後、磁気ディ

徴とする。Means for Solving the Problem] The method for manufacturing a magnetic disk medium of the present invention includes applying a protective film to a magnetic disk medium using a protective film coating machine, and then removing excess protective film material from the end surface of the magnetic disk medium. It is characterized by
[実施例コ 次に本発明について図面を参照して説明する。[Example code] Next, the present invention will be explained with reference to the drawings.
第1図は本発明の一実施例、すなわち、保護膜塗布後の
端面の余分な保護膜材料4を除去する方法を示している
。保護膜塗布後にノズル1からアルコールが塗布され余
分な保護膜材料4の除去を実施する。FIG. 1 shows an embodiment of the present invention, ie, a method for removing excess protective film material 4 from the end face after coating the protective film. After applying the protective film, alcohol is applied from the nozzle 1 to remove excess protective film material 4.

記録装置内部での塵埃の発生も低減できる効果を奏する
。Effects of the Invention As explained above, the present invention provides a magnetic disk medium with an alcohol cloth after applying a protective film to the end surface.
Since the excess protective film on the end face can be removed, the generation of dust inside the magnetic recording device can also be reduced.
