摘要： Embodiments of the present invention provide recording area separated magnetic recording media (DTMs, BPMs) allowing magnetic heads to fly lower. According to one embodiment, the recording area separated magnetic recording media are configured so that magnetic recording layers have parts with the relatively higher element ratio of a ferromagnetic material, and parts with the lower element ratio of the ferromagnetic material, occurring periodically in the in-plane direction, and the average height from the substrate surface of the parts with the relatively higher element ratio of a ferromagnetic material is higher than the average height from the substrate surface of the parts with the lower element ratio of the ferromagnetic material. In producing recording area separated magnetic recording media with the element ratio of a ferromagnetic material relatively lowered by ion implantation, preliminarily etching the part to be ion implanted makes the height after ion implantation relatively lower than the non-implanted part.

摘要： A magnetic recording medium includes at least a substrate, a recording layer formed of a non-magnetic underlying layer and a ferromagnetic thin film, deposited on the substrate, a sputtered carbon protective layer and a lubricant layer overlying the recording layer. The sputtered carbon protective layer is laminate layer formed by sputtering alternating first and second carbon layers, wherein a Young's modulus in a head pressing direction is twice or more larger than a Young's modulus in a head running direction. In this way, the durability of the magnetic disk can be significantly improved, and consequently, the protective layer can be made extremely thin, so that it can also contribute to an increased recording density.
