Abstract: A coating apparatus for magnetic data storage disks is operable to transport a disk in a disk holding fixture from a first coating area to a second coating area via roller wheels along a first path. A wheel located along the first path between the first coating area and the second coating area within a sealed enclosure is adjusted such that deflection of the disk holding fixture when traversing the disk transport wheel is reduced, such as by adjusting a leadscrew coupled to the disk holding fixture and a frame of the disk coating apparatus. Adjustment is made with the disk coating apparatus sealed and under vacuum, as the position of the disk transport wheel being adjusted may be different under vacuum than under atmospheric pressure. Adjustment is verified by processing a test disk and measuring forces applied to the test disk during transport through the disk coating apparatus.

Abstract translation: 用于磁数据存储盘的涂覆装置可操作以沿着第一路径将盘保持固定装置中的盘从第一涂覆区域经由辊轮传送到第二涂覆区域。 调节在密封外壳内沿着第一涂覆区域和第二涂覆区域之间的第一路径设置的轮子，使得当盘片传送轮横过时，盘保持夹具的偏转减小，例如通过调节联接到盘的丝杠 保持固定装置和盘式涂装装置的框架。 由于盘片运输轮的位置被调整，在密封的真空下进行调整，真空度可能不同于大气压。 通过处理测试盘和测量在通过盘式涂布设备传送过程中施加到测试盘的力量来验证调整。

Abstract: A device includes a housing unit and a number of magnets. The housing unit includes a number of holes therein. The magnets are positioned in the holes. The magnets have a same pole orientation. It is appreciated that the magnets are positioned in the holes to form a mechanically balanced and magnetically unbalanced structure.
