    • A magnetic disk is provided wherein a non-magnetic substrate, a magnetic layer, a protection layer, and a lubrication layer are sequentially stacked. The surface of the lubrication layer has irregular structure patterns along a circumferential direction of the magnetic disk that have circumferential lengths that each correspond to a central angle. The irregular structure patterns may be formed by an adsorption between the lubrication layer and the surface of the protection layer. When a natural frequency of a magnetic head slider used to record to the magnetic disk is f and the magnetic disk rotation speed is R0, the central angle is set so as not to coincide with an angle θ0 expressed by θ0=360×(R0/60)/(f×1000).
    • 提供一种磁盘,其中依次层叠非磁性基板,磁性层,保护层和润滑层。 润滑层的表面沿着磁盘圆周方向具有不均匀的结构图案,其周向长度各自对应于中心角。 可以通过润滑层与保护层的表面之间的吸附形成不规则结构图案。 当用于记录到磁盘的磁头滑块的固有频率为f并且磁盘转速为R0时,中心角被设定为不与角度和角度一致; 0表示为&thetas; 0 = 360 ×(R0 / 60)/(f×1000)。
