Mubyiciro bifatika, imikorere ya ultra-ntoya ya titanium nitride ibyuma magnetiki idirishya ryamadirishya yimodoka yamenyekanye cyane. Ba nyirubwite benshi bavuze ko nyuma yo gushiraho film ya titanium nitride ya titanium, kureba imbere mumodoka byahuje neza kandi bikaba byizuba cyangwa imvura. Cyane cyane iyo utwaye nijoro, ultra-make haze idirishya ryamadirishya arashobora kugabanya cyane urumuri rwatewe n'amatara yimodoka ziza kandi kuzamura umutekano wimodoka.
