摘要： A lubricating film is provided for a magnetic disk having a data region and a CSS region formed on its surface. The lubricating film ensures low stiction and good resistance to contact sliding in the data region and also ensures good CSS durability in the CSS region. Therefore, it is possible to provide a magnetic disk and a magnetic recording/reproducing device which do not cause problems with sliding between the magnetic head and the magnetic disk while the apparatus is running normally and even when the apparatus stops accidentally. The lubricating film formed in the data region of the magnetic disk is firmly fixed to the surface of the magnetic disk and is hardly liable to stiction. In addition, it is thick enough to ensure good durability even in the case of contact sliding. The lubricating film formed in the CSS region is composed of a lubricant which is firmly fixed to the surface of the magnetic disk and another lubricant which is weakly fixed to the surface of the magnetic disk; therefore, it is superior in CSS durability. This contributes to the highly reliable magnetic disk and magnetic recording/reproducing device.
摘要翻译：为具有形成在其表面上的数据区域和CSS区域的磁盘提供润滑膜。润滑膜确保数据区域的低粘滞性和良好的接触滑动性，并且还确保CSS区域中的良好的CSS耐久性。因此，可以提供一种磁盘和磁记录/再现装置，当装置运行正常并且即使装置意外停止时也不会在磁头和磁盘之间滑动的问题。形成在磁盘的数据区域中的润滑膜牢固地固定在磁盘的表面上，并且几乎不易于凝固。此外，即使在接触滑动的情况下，其足够厚以确保良好的耐久性。形成在CSS区域中的润滑膜由固定在磁盘表面上的润滑剂和与磁盘表面弱固定的另一种润滑剂构成。因此，CSS耐用性优越。这有助于高度可靠的磁盘和磁记录/再现装置。

摘要： The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.
