摘要： Aspects are directed to recording media with enhanced magnetic properties for improved writability. Examples can be included or related to methods, systems and components that allow for improved writability while reducing defects so as to obtain uniform magnetic properties such as uniformly high anisotropy and narrow switching field distribution. Some examples include a recording medium with an exchange tuning layer inserted between the hard layer and the soft, semi-soft or thin semi-hard layer so as to maximize the writability improvement of the media. Preferably, the exchange tuning layer is granular and reduces or optimizes the vertical coupling between the hard layer and the soft, semi-soft or semi-hard layer of a magnetic recording or storing device.
摘要翻译： 方面涉及具有增强的磁性能的记录介质以改善可写性。 可以包括或涉及允许改善可写性同时减少缺陷以获得均匀的磁性能如均匀高的各向异性和窄的开关场分布的方法，系统和组件的实例。 一些示例包括具有插入在硬层和软，半软或薄半硬层之间的交换调谐层的记录介质，以便最大限度地提高介质的可写性。 优选地，交换调谐层是粒状的并且减小或优化硬记录层与磁记录或存储装置的软，半软或半硬层之间的垂直耦合。

摘要： A stack including a crystallographic orientation interlayer, a magnetic zero layer disposed on the interlayer, and a magnetic recording layer disposed on the magnetic zero layer is disclosed. The magnetic zero layer is non-magnetic or has a saturation magnetic flux density (Bs) less than about 100 emu/cc. The magnetic zero layer and the magnetic layer include grains surrounded by a non-magnetic segregant. The magnetic zero layer provides a coherent interface between the interlayer and the magnetic layer with a lattice mismatch less than about 4%.
