摘要： A bit patterned magnetic recording medium for use in HAMR, which is optimized for optical coupling efficiencies and improved magnetic read-back coupling. The medium comprises bit-patterned magnetic recording elements, each corresponding to a magnetic data bit, and each comprising a cluster of discrete and separated magnetic grains. The desired packing fraction may be obtained by defining the number of grains within a bit, while bit-patterning provides efficient optical transmission. The grains have an effective packing fraction that enhances magnetic read-back signals, and the bits are distributed in a pattern having a packing fraction that enhances the optical coupling efficiency. The bits and/or the grains may be substantially thermally and optically isolated.

摘要： A method and system for magnetic recording using self-organized magnetic nanoparticles is disclosed. The method may include depositing surfactant coated nanoparticles on a substrate, wherein the surfactant coated nanoparticles represent first bits of recorded information. The surfactant coating is then removed from selected of the surfactant coated nanoparticles. The selected nanoparticles with their surfactant coating removed may then be designated to represent second bits of recorded information. The surfactant coated nanoparticles have a first saturation magnetic moment and the selected nanoparticles with the surfactant coating removed have a second saturation magnetic moment. Therefore, by selectively removing the surfactant coating from certain nanoparticles, a write operation for recording the first and second bits of information may be performed. A read operation may be carried out by detecting the different magnetic moments of the surfactant coated nanoparticles and the non-surfactant coated nanoparticles.
摘要翻译：公开了一种使用自组织磁性纳米颗粒进行磁记录的方法和系统。该方法可以包括在衬底上沉积表面活性剂涂覆的纳米颗粒，其中表面活性剂涂覆的纳米颗粒表示记录信息的第一位。然后从选择的表面活性剂涂覆的纳米颗粒中除去表面活性剂涂层。然后将其去除其表面活性剂涂层的所选择的纳米颗粒指定为表示记录信息的第二位。表面活性剂涂覆的纳米颗粒具有第一饱和磁矩，并且去除了表面活性剂涂层的所选纳米颗粒具有第二饱和磁矩。因此，通过从某些纳米颗粒中选择性地去除表面活性剂涂层，可以执行用于记录信息的第一和第二位的写入操作。可以通过检测表面活性剂涂覆的纳米颗粒和非表面活性剂涂覆的纳米颗粒的不同磁矩来进行读取操作。

摘要： A patterned magnetic layer is formed by bombardment of a masked high Mrt magnetic layer with a combination of both heavy ion species and light ion species. The method can be implemented as sequential process steps or in a single process step with the proper heavy/light ion species mixture. Advantageously, the combined heavy/light ion species bombardment method results in a patterned magnetic layer having high topographical uniformity across its surface.
