Popis: | We studied the magnetic field sensitivity in a double layer which was composed of a TbFeCo recording layer with low Tb content and a high-Tc RE-rich DyFeCo ultrathin layer. The Tb14Fe82Co4/Dy30Fe35Co35 double layer has better magnetic field sensitivity than a TbFeCo single recording layer. We concluded that the high C/N of the double layer disk was caused by the large MS of the recording layer and suppression of micro-domain nucleation by the ultra-thin DyFeCo layer. |
