摘要： A granular perpendicular magnetic recording medium comprises a non-magnetic substrate and a granular perpendicular magnetic recording layer overlying the substrate, comprising a first granular perpendicular magnetic layer proximal the substrate and having a first saturation magnetization (Ms)1, and a second granular perpendicular magnetic layer distal the substrate and having a second, different saturation magnetization (Ms)2. Also disclosed is a method of fabricating the granular perpendicular magnetic recording medium.

摘要： A data recording device employs a bit patterned data recording medium that has an array of rows that are offset to one another. The rows are offset such that the bits are staggered in a direction that is normal to the direction in which the rows extend. The increased bit aspect ratio of the staggered bit pattern recording medium increases the linear recording density and enables a higher data recording rate.
摘要翻译： 数据记录装置采用具有彼此偏移的行阵列的位图案数据记录介质。 行被偏移，使得位在与行延伸的方向垂直的方向上交错。 交错位图记录介质的增加的位长宽比增加了线性记录密度并且能够实现更高的数据记录速率。
