%X Na-no si-zed di-a-mond-li-ke car-bon (DLC) films do-ped with ni-tro-gen and hydrogen are ma-te-ri-als of cho-i-ce as a mec-ha-ni-cal and cor-ro-sion pro-tec-tion bar-ri-er for mag-ne-tic layer of the com-pu-ter hard disks. Ove-rall thic-kness of a-C:N/a-C:H layer is bellow 2 nm and is usu-ally ac-com-pa-nied by 0.5 nm thin flash layer of Cr. To ob-tain den-se and void-free DLC films, dif-fe-rent pla-sma and ion be-am so-ur-ces ope-ra-ted with hydrocarbon ga-ses are now re-pla-cing sput-te-ring de-po-si-tion tec-hni-qu-es. For the film charac-te-ri-za-tion, ma-inly used are non-de-struc-ti-ve op-ti-cal tec-hni-qu-es li-ke mic-ro-Raman spec-tro-scopy and op-ti-cal sur-fa-ce analysis. Va-ri-o-us elec-troc-he-mi-cal and bu-si-ness environmen-tal tests are com-mon for the cor-ro-sion pro-tec-tion eva-lu-a-tion. Ca-pa-bi-li-ti-es of the Ruther-ford back-scat-te-ring spec-tro-scopy ha-ve been de-mon-stra-ted in re-ve-a-ling the cobalt migration from the mag-ne-tic layer. In-cor-po-ra-tion of the tri-bo-logy layer in-to the mag-ne-tic layer, eit-her oxi-de, car-bi-de or ni-tri-de-ba-sed, and im-pro-ve-ment of the lu-bri-cant pro-per-ti-es, are the main de-ve-lop-men-tal area in the mo-dern hard disk dri-ve struc-tu-res.
