摘要： PROBLEM TO BE SOLVED: To provide a magnetic recording medium and a hard amorphous carbon film for magnetic recording head containing an ultra small amount of hydrogen.SOLUTION: A magnetic recording medium of one embodiment includes: at least one ground layer formed on a nonmagnetic substrate; a magnetic recording layer formed on the ground layer; and an overcoat formed on the magnetic recording layer. The overcoat is an amorphous carbon layer in which a ratio of spbond with respect to spbond (sp/( sp+ sp)) is at least 0.5 in a film thickness direction of the overcoat. A hydrogen content of the overcoat at the center layer in the film thickness direction thereof is 0.1 atm.% to 0.6 atm.%. Further, a device and a method are also provided.

摘要： PROBLEM TO BE SOLVED: To provide a recording area separation type magnetic recording medium (DTM, BPM) which is optimal for reducing flying height of a magnetic head.SOLUTION: There is provided a magnetic recording medium in which a portion having a relatively high element ratio of a ferromagnetic material and a portion 13 having a low element ratio thereof periodically exist in an in-plane direction in magnetic recording layers 6 and 7, and an average height of the portion having the relatively high element ratio of the ferromagnetic material from a substrate surface is higher than that of the portion having the low element ratio thereof from the substrate surface. In manufacturing of the recording area separation type magnetic recording medium in which the element ratio of the ferromagnetic material is relatively reduced by ion implantation, etching an ion implantation portion in advance allows the height after the ion implantation to be relatively reduced compared to the height of a portion having no ions implanted thereto.
