    • Embodiments of the present invention provide a manufacturing method that can form a track guide separation area of a magnetic disk substrate constituting a patterned medium represented by a discrete track medium or bit patterned medium suitable for high recording density, uniformly on the whole surface of the magnetic disk substrate, and accurately according to the mask. According to one embodiment, a soft magnetic film, an under coating film, and a magnetic film are formed on a substrate. A mask having an arbitrary pattern shape provided for forming the track guide separation area in the magnetic film is formed on the magnetic film, and the track guide separation area is formed by irradiating ions and electrons onto the surface of the magnetic film and applying an intermittent voltage to the substrate, thereby non-magnetizing the area irradiated.
    • 本发明的实施例提供一种制造方法,其可以形成构成由适于高记录密度的离散轨道介质或位图案化介质表示的图案化介质的磁盘基板的导轨分离区域,均匀地在磁性的整个表面上 盘基片,并根据掩模准确。 根据一个实施例,在基板上形成软磁性膜,底涂层膜和磁性膜。 在磁性膜上形成设置用于形成磁性膜中的导轨分隔区域的具有任意图案形状的掩模,并且通过将离子和电子照射在磁性膜的表面上并施加间歇的方式形成轨道引导件分离区域 电压到基板,从而不使被照射的区域磁化。
