  • Patent number: 4290734
    Abstract: Apparatus and method for stacking rigid magnetic discs so that the discs do not come into contact with one another. A hollow elongate member has at least two elongate axial recesses terminating at openings at each end of the recesses. The outer surface of the elongate member has dimensions slightly less than the inner dimensions of the central apertures of the discs. Endless loops are mounted so that the loops traverse the respective recesses and return within the elongate member. Each loop has a plurality of equally spaced nibs projecting outwardly beyond the outer surface of the elongate member. A drive element is located within the elongate member and is attached to each of the loops. The drive member is moved axially within the elongate member to move the loops in unison and thereby allow serial loading and unloading of the discs on sequential nibs. A sensor system may be included to automatically move the loops to space the discs each time a disc is loaded or unloaded.
