LOC disk positioner
Designed and built this optical disk positioner for one gigabyte glass disk aging studies at the Library of Congress. The positioner was mounted onto a looking up metallurgical microscope. The general idea was to remount the disk and find a specific data bit to examine its degradation over time.
