技術摘要 / Our Technology: |
本發明提供一種浸透式垂直磁記錄媒體,其包括:一基板;一底層,其位於該基板上;一緩衝層,其位於該底層上;以及一記錄層,其位於該緩衝層上,其中該記錄層包含一磁性基質以及以浸透(percolated)方式分佈於該磁性基質內之複數非磁性粒子。當非磁性粒子之間的距離小於磁性粒子的晶粒尺寸時,磁區在移動的過程中便會傾向以非磁性粒子做為邊界移動,而非傳統式的以磁晶粒的晶界為邊界移動,因此得在不降低磁晶粒的尺寸下直接縮小磁矩轉換區的大小。藉由本發明,可解決超小晶粒之熱穩定性不佳的課題,又能使磁區轉換過程更加順暢,實現超高記錄密度的可能性。
A magnetic recording medium is provided in the present invention. The magnetic recording medium including a substrate; a base layer disposed on the substrate; an intermediate layer disposed on the base layer; and a recording layer disposed on the intermediate layer and including a magnetic matrix and a plurality of non-magnetic particles percolated in the magnetic matrix.
