摘要： A media for perpendicular recording and a method of creating the media is provided. The media includes a hard recording layer and a soft underlayer (SUL). The SUL is composed of at least two anti-ferromagnetically coupled (AFC) sub-underlayers. The sub-underlayers respond to a magnetic field established during dynamic reversal with respective magnetic fields. The sub-underlayers are formed and disposed to differ in one or more magnetic moment, anisotropy, and thickness, so that their respective magnetic fields constructively interfere in one or more points in the hard recording layer, thereby reducing a total SUL magnetic field response to the dynamic reversal field approximately to zero at one or more points in the hard recording layer, which reduces side track erasure.
摘要翻译：提供了用于垂直记录的介质和创建介质的方法。介质包括硬记录层和软底层（SUL）。 SUL由至少两个反铁磁耦合（AFC）子底层组成。副底层响应于用相应的磁场在动态反转期间建立的磁场。亚底层被形成和设置为在一个或多个磁矩，各向异性和厚度上不同，使得它们各自的磁场建构性地干扰硬记录层中的一个或多个点，从而减少总SUL磁场响应在硬记录层中的一个或多个点处的动态反转场大致为零，这减少了侧轨道擦除。

摘要： A collimator system is disclosed for use in an in-line pass-by sputtering system during the fabrication of recording media to improve the data storage density and read/write performance characteristics of the media. The collimator system includes a collimator shield and a collimator honeycomb. The shield includes a rectangular tube having a flange and a frame at inner and outer ends, respectively. The various components of the shield in part serve to prevent possible contamination of substrates due to target atom accumulation on the chamber walls during the sputtering process. The collimator honeycomb is provided for blocking target atoms from contacting the substrate at low incident angles. The collimator honeycomb is comprised of a plurality of collimators which are identical to each other. In a preferred embodiment, the collimators have a hexagonal cross-section taken from a perspective perpendicular to the substrate. The collimators may also have other geometric shapes. It is also contemplated that more than one collimator honeycomb level be used in alternative embodiments.
