    摘要： A magnetic disc is provided with a magnetic layer, a protection layer and a lubrication layer in this order on a substrate. After successively forming the magnetic layer and the protection layer on the substrate, the protection layer is exposed to plasma under normal pressure, then, the lubrication layer is formed on the protection layer. The plasma is generated in at least one kind of gas selected from among nitrogen gas, argon gas, oxygen gas, and fluorine hydrocarbon gas. The protection layer is a hydrogenated carbon protection layer.

    摘要： In a magnetic recording disk 1 including a magnetic layer 12, a protective layer 13, and a lubricating layer 14, the lubricating layer 14 is made from a lubricant prepared from a composition. The weight change of the lubricant ranges from −20% to −50% at 300° C. in the case where the lubricant is subjected to thermogravimetric analysis in such a manner that the lubricant is heated from 40° C. to 500° C. at a heating rate of 10° C./min. The lubricant has a maximum peak at about 300° C. in the case where the lubricant is subjected to differential thermal analysis in the same manner as described above. The lubricant can be quantitatively measured for heat resistance. Therefore, a magnetic recording disk exhibiting stable performance at high temperatures and a method for manufacturing such a magnetic recording disk can be obtained.
