Abstract
The optical storage medium of the present invention comprises: (1) a substrate; (2) ultra-thin recording layers containing a dye; and (3) controlling layers. The recording layers and the controlling layers are accumulated alternately, and the uppermost layer is a controlling layer. The optical storage medium of the present invention contains dye cohesions in the recording layer in an extremely small amount and of extremely small size so that the medium can store a high density of records.
