    • A perpendicular magnetic recording medium has an “exchange-spring” type magnetic recording layer (RL) formed of two ferromagnetic layers with substantially similar anisotropy fields that are ferromagnetically exchange-coupled by a nonmagnetic or weakly ferromagnetic coupling layer. Because the write head produces a larger magnetic field and larger field gradient at the upper portion of the RL, while the field strength decreases further inside the RL, the upper ferromagnetic layer can have a high anisotropy field. The high field and field gradient near the top of the RL, where the upper ferromagnetic layer is located, reverses the magnetization of the upper ferromagnetic layer, which then assists in the magnetization reversal of the lower ferromagnetic layer. Because both ferromagnetic layers in this exchange-spring type RL have a high anisotropy field, the thermal stability of the medium is not compromised. The medium shows improved writability, i.e., a low switching field, as well as lower intrinsic media noise, over a medium with a conventional single-layer RL.
    • 垂直磁记录介质具有由具有基本相似的各向异性场的两个铁磁层形成的“交换弹簧”型磁记录层(RL),其通过非磁性或弱铁磁耦合层进行铁磁交换耦合。 由于写头在RL的上部产生较大的磁场和较大的场梯度,而在RL内的场强进一步降低,所以上铁磁层可以具有高的各向异性场。 在RL的顶部附近的高场磁场梯度,其中上铁磁层位于其上,反转上铁磁层的磁化,其随后有助于下铁磁层的磁化反转。 由于这种交换弹簧型RL中的两个铁磁层具有高各向异性场,所以介质的热稳定性不受影响。 在具有常规单层RL的介质上,介质显示改进的可写性,即低切换场,以及较低的固有介质噪声。
