    • A perpendicular magnetic recording medium (16) includes a hard magnetic recording layer (42), a soft magnetic layer (40) and a non-magnetic intermediate layer (50) between the hard magnetic recording layer (42) and the soft magnetic layer (40). The non-magnetic intermediate layer (50) comprises a seedlayer (52) formed adjacent the soft magnetic layer (40) and an underlayer (54) formed between the seedlayer (52) and hard magnetic recording layer (42). The underlayer (54) comprises Ru or CrRu. The seedlayer (52) comprises CoCrRu, CoCr, W, Ta, Mo, Hf, or Ti. The non-magnetic intermediate layer (50) provides a means for inducing a substantially (00.2) orientation in the hard magnetic recording layer (42).
    • 垂直磁记录介质(16)包括在硬磁记录层(42)和软磁层(42)之间的硬磁记录层(42),软磁层(40)和非磁中间层(50) 40)。 非磁性中间层(50)包括邻近软磁层(40)形成的种子层(52)和形成在种层(52)和硬磁记录层(42)之间的底层(54)。 底层(54)包括Ru或CrRu。 种子层(52)包括CoCrRu,CoCr,W,Ta,Mo,Hf或Ti。 非磁性中间层(50)提供了用于在硬磁记录层(42)中诱导基本(00.2)取向的装置。
