摘要： A patterned perpendicular magnetic recording medium, such as a disk for use in hard disk drives, has a flux channeling layer (FCL) located below the recording layer (RL) in each of the discrete data islands. The disk includes a substrate, a soft underlayer (SUL) of soft magnetically permeable material on the substrate, and a nonmagnetic exchange break layer (EBL) on the SUL. A nonmagnetic separation layer (SL) is located between the FCL and the RL in the islands. The FCL has an anisotropy field substantially lower than the anisotropy field of the RL, and a magnetization equal to or higher than the magnetization of the RL. The FCL is saturated at a much lower field than the RL and thus channels the magnetic flux from the write head through the island positions. The dipolar fields from the RL above the FCL polarize the magnetization of the FCL parallel to the magnetization direction of the RL in the absence of an external field, to thereby enhance the readback signal.

摘要： A perpendicular magnetic recording medium has a multilayer recording layer (RL) structure that includes a ferromagnetic intergranular exchange enhancement layer for mediating intergranular exchange coupling in the other ferromagnetic layers in the RL structure. The RL structure may be a multilayer of a first ferromagnetic layer (MAG1) of granular polycrystalline Co alloy with Ta-oxide, a second ferromagnetic layer (MAG2) of granular polycrystalline Co alloy with Si-oxide, and an oxide-free CoCr capping layer on top of and in contact with MAG2 for mediating intergranular exchange coupling in MAG1 and MAG2. The RL structure may also be a multilayer of an intergranular exchange enhancement interlayer (IL) in between two ferromagnetic layers, MAG1 and MAG2, each with reduced or no intergranular exchange coupling. Because the IL is in direct contact with both MAG1 and MAG2, it directly mediates intergranular exchange coupling in each of MAG1 and MAG2.

摘要： Perpendicular magnetic recording media and methods of fabricating perpendicular magnetic recording media are described. The perpendicular magnetic recording medium of one embodiment includes an interlayer, an underlayer, and a perpendicular magnetic recording layer. The interlayer is comprised of a Ni-alloy having the characteristics of being nonmagnetic and having an FCC structure. The alloying element for the Ni-alloy may comprise one of V or Cr, or may comprise one of V, Cr, or W. The concentration of the alloying element is set such that the concentration of the alloying element is high enough to make the Ni-alloy non-magnetic, while low enough to maintain an FCC structure for the Ni-alloy.

摘要： A dual-layer type perpendicular magnetic recording disk for use in a perpendicular magnetic recording system that uses a single pole recording head has a laminated underlayer that has at least two ferromagnetic films exchange-coupled across an antiferromagnetic coupling layer. The magnetic moments of the ferromagnetic layers in the laminated underlayer are oriented antiparallel. The laminated underlayer provides a soft magnetically permeable flux return path without undesirable domain walls and associated media noise, with controllable permeability and minimization of saturation of the upper ferromagnetic layers. In one embodiment the moments of the ferromagnetic layers in the underlayer are oriented generally radially on the disk. In another embodiment the moments are oriented generally circumferentially in the track direction on the disk, so that the beneficial effect of the soft magnetic underlayer occurs primarily only during the writing process.
摘要翻译：在使用单极记录头的垂直磁记录系统中使用的双层型垂直磁记录盘具有层叠底层，其具有穿过反铁磁耦合层交换耦合的至少两个铁磁膜。层叠底层中的铁磁层的磁矩反平行取向。层压底层提供了柔软的导磁通量返回路径，不需要不必要的畴壁和相关的介质噪声，具有可控的磁导率和最小化上层铁磁层的饱和度。在一个实施例中，底层中的铁磁层的力矩通常在盘上径向定向。在另一个实施例中，力矩在盘上的轨道方向上大致圆周地取向，使得软磁性底层的有益效果主要仅在写入过程中发生。
