Abstract

Some data storage devices include several discs mounted on a spindle. The surface of each disc is formed with a coating of magnetizable material. The coated surfaces of adjacent discs must be spaced apart so that heads for use in reading or writing data on the surfaces can be inserted between the discs. The discs are normally formed from flat plates and are spaced apart on the spindle by spacers. Therefore, in assembling discs onto a spindle the assembly process involves stacking discs and spacers alternately.
