Abstract
An information handling system optical medium disc is labeled by removing portions of disc's polycarbonate material from the non-storage side of the disc to form an image. Formed images define a label in various forms including letters, Braille, dot-matrix holes or bas-relief. Another material fills in the removed polycarbonate to reinforce the image with visual effects, such as raising the image or providing color to the image, and to maintain the balance of the disc for rotation in an optical disc drive.
Claims20
A method for marking an optical medium, the method comprising:
- writing information with a laser through a storage surface of the optical medium at a predetermined material depth;
- and
- removing from a non-storage surface of the optical medium some material disposed from the non-storage surface to not more than the predetermined depth, the removed material defining a label.
An optical medium having a storage side and a non-storage side, the optical medium comprising:
- polycarbonate material having a predetermined thickness and operable to provide plural reflective properties in response to illumination by a laser through the storage side at a predetermined material depth, the plural reflective properties associated with stored information, wherein the polycarbonate material between the predetermined material depth and the non-storage side is selectively physically modified to present a label.
A method for labeling an optical medium, the method comprising:
- preparing a disc of polycarbonate having a predetermined thickness;
- altering a label surface of the disc to form a label by removing at least some polycarbonate not greater than a predetermined depth;
- altering the polycarbonate at the predetermined depth to have varying reflective qualities associated with information;
- and
- illuminating the polycarbonate with a laser through a storage surface at the predetermined depth to read the information.
