The hard disk, also known as fixed disk, is composed if disk sheets of magnetic substance coated with mental material and read-write devices of the disk sheets.
硬盘又叫固定盘有金属材料涂上磁性物质的盘片与盘片读写装置组成。

Because the accretion disk itself is believed to be magnetized, the rotation of the disk can twist the magnetic field lines into a helix.
为我们相信吸积盘本身是被磁化的，圆盘的旋转可将磁力线扭曲成螺旋线圈状。

To study the adsorptive mechanism and sliding frictional mechanism between the head and disk of the magneticdisk unit, a qualitative analysis theory is given in this paper.
