Abstract
The disclosure is directed to an optical disk with a topographical surface. The topographical surface may be formed in the optical disk to create an aesthetic label for the optical disk. The topographical surface may include raised features that refract, diffuse, reflect, or diffract light that makes images of the label viewable to a user. The topographical surface may be at least partially radially coincident with a data surface of the optical disk. An optical disk that includes a topographical surface as the label may not require an additional layer or process to create the label. In some examples, the topographical surface may include raised features of high spatial frequency and configured to create a hologram label that displays images to the user.
Claims20
An optical disk comprising:
- a disk-shaped substrate;
- and
- a topographical surface formed into the disk-shaped substrate that creates a label of the optical disk, wherein the topographical surface is disposed in an outer surface of the optical disk.
A method comprising:
- molding a topographical surface into a disk-shaped substrate of an optical disk with a stamper having an inverse topography, wherein:
- the topographical surface creates a label of the optical disk;
- and
- the topographical surface is disposed in an outer surface of the optical disk.
A system for creating optical disk substrates molded with labels comprising:
- a first stamper including an inverse topography, wherein the inverse topography defines a topographical surface that creates the labels in an outer surface of the optical disk substrates during molding processes;
- a second stamper that defines a second surface of the optical disk substrates;
- and
- a cavity ring that separates the first stamper from the second stamper.
