ABSTRACT:
A method for making an optical memory storage medium which has a transparent substrate with void cells of empty spaces and ablative material on the cell walls is disclosed. In one example, a base plate is coated with a masking layer. Pits are formed on the plate by mechanically stamping the masking layer and the base plate with a punch. A layer of ablative material is next applied on the pitted plate. The masking layer is then removed, together with any ablative material on it. The base plate is joined with a cover plate that seals the top of the pits to form void cells. In another example, a base plate is coated with a photo resist. The photo resist is exposed and developed. Pits are formed on the plate by etching the uncovered areas of the base plate. This is followed by the application of ablative material and the removal of the photo resist. The base plate is joined with a cover plate that seals the top of the pits to form void cells.
