Abstract
A first disk carrier constructed in accordance with the invention is substantially circular, and has a size and shape such that it can be placed in an opening in a second, larger disk carrier. In one embodiment, the second, large disk carrier is a conventional disk carrier, e.g. used to hold a substrate during a magnetic disk manufacturing process. The first disk carrier is circular, and has a diameter equal (or substantially equal) to common substrates currently being manufactured. Therefore, the first disk carrier fits in and can be held by the second disk carrier. The first disk carrier has one or more openings for holding one or more substrates that have a diameter substantially less than the diameter of the opening of the second disk carrier.
