    • A magnetic recording medium and a manufacturing method thereof are provided to apply servo signal processing for continuous recording media to discrete track media or pattern media by magnetizing burst pieces of burst in different directions in order to obtain signal similar to the AC signal of continuous recording media. A magnetic recording medium comprises a data area having a plurality of data tracks(16), and a magnetic recording layer including a servo region having servo burst for the following of data track. The servo burst includes a plurality of bursts arranged to cross over each other in the track direction. Each of the bursts includes a plurality of burst pieces with different coercive force, where the coercive force of the burst pieces is regulated by making the size of the burst pieces different.
    • 提供磁记录介质及其制造方法,通过在不同方向上磁化突发脉冲串来对连续记录介质施加伺服信号处理,以便获得与连续记录介质的AC信号类似的信号 。 磁记录介质包括具有多个数据轨道(16)的数据区域和包括具有用于随后的数据轨道的伺服脉冲串的伺服区域的磁记录层。 伺服脉冲串包括布置成在轨道方向上彼此交叉的多个脉冲串。 每个脉冲串包括具有不同矫顽力的多个脉冲片,其中通过使脉冲片的尺寸不同来调节脉冲片的矫顽力。

    • A magnetic recording medium including a magnetic recording layer and a substrate that supports the magnetic recording layer is provided. At least two underlayers including a nonmetallic underlayer are placed between the magnetic recording layer and the substrate. The perpendicular magnetic recording medium uses a double-layered or tri-layered underlayer. Accordingly, a perpendicular magnetic recording layer can have a high perpendicular magnetic anisotropic energy constant Ku due to a third underlayer and have small crystal grains and a small exchange coupling due to a second underlayer below the third underlayer. Thus, the perpendicular magnetic recording layer can have a good thermal stability, high-density recording characteristics, and excellent SNR characteristics.
    • 提供了包括磁记录层和支撑该磁记录层的基板的磁记录介质。 在磁记录层和衬底之间放置至少两个包括非金属底层的底层。 垂直磁记录介质使用双层或三层底层。 因此,由于第三底层,垂直磁记录层可以具有高的垂直磁各向异性能量常数Ku,并且由于第三底层下面的第二底层而具有小晶粒和小交换耦合。 因此,垂直磁记录层可以具有良好的热稳定性,高密度记录特性和优异的SNR特性。
