    • A magnetic polishing method capable of easily and satisfactorily polishing the inner peripheral end face of a circular hole (1) at the center part of a disk substrate (2) even if the diameter of the circular hole is reduced. By this method, a large quantity of disk substrates with stable quality can be supplied, thermal asperity trouble and head crush can be prevented from occurring on a magnetic disk, and the density of the information recording surface of the magnetic disk can be increased. In the method for polishing the inner peripheral end face of the circular hole (1) at the center part of the disk substrate (2), a magnetic field is formed on the inner peripheral side of the circular hole (1), abrasive materials (4) including magnetic particles and abrasive grains are held by the magnetic field in the circular hole, and the magnetic field is moved to the inner peripheral end face of the circular hole (1) to move the abrasive materials (4) to the inner peripheral end face of the circular hole (1) for polishing the inner peripheral end face of the circular hole (1).
    • 即使圆孔的直径减小,也能够容易且令人满意地研磨盘基板(2)的中央部的圆形孔(1)的内周端面的磁性研磨方法。 通过这种方法,可以提供大量的质量稳定的盘基片,可以防止在磁盘上发生热凹凸故障和头部挤压,并且可以提高磁盘的信息记录表面的密度。 在盘状基板(2)的中央部的圆形孔(1)的内周端面的研磨方法中,在圆形孔(1)的内周侧形成磁场,研磨材料 4)包括磁性颗粒和磨粒由圆孔中的磁场保持,并且磁场移动到圆孔(1)的内周端面,以将研磨材料(4)移动到内周 圆孔(1)的端面用于研磨圆孔(1)的内周端面。

    • A sputtering target comprises a backing plate, a mosaic layer laid on the backing plate, and a keep jig contacting the inner peripheral edge and outer peripheral edge of the mosaic layer, thus attaching the layer to the backing plate. The mosaic layer is substantially circular and consists of a first group of fan-shaped plates made of a first target material and a second group of fan-shaped plates of a second target material. The plates of the second group are divided into subgroups each consisting of at least one plate. These subgroups are interposed among the fan-shaped plates of the first group. The plates have a notch in the narrower end, are connected side by side to each other, and are arranged with top surfaces flush with one another.
    • 溅射靶包括背板,镶嵌在背板上的马赛克层,以及与马赛克层的内周边缘和外周边缘接触的保持夹具,从而将该层附着到背板上。 马赛克层基本上是圆形的,由第一组由第一目标材料制成的扇形板和第二组第二靶材料的扇形板组成。 将第二组的板分成各自由至少一个板构成的亚组。 这些子组插入第一组的扇形板之间。 这些板在较窄的端部具有切口,并排地彼此连接,并且被布置为具有彼此齐平的顶表面。
