An optical memory device.

摘要

An optical memory device comprising a first light-permeable substrate (1), a second light-permeable substrate (4) and a plurality of strip-shaped magneto-optic recording layers (2) that are disposed with a gap between the first substrate (1) and the second substrate (4), wherein the optical path length from the outer surface of the first substrate (1) to the recording layers (2) is approximately equal to the optical path length from the outer surface (4) of the second surface to the recording layers (2).
