ABSTRACT:
A new compact disk ("CD") is formed providing a bright, metallic presentation of indicia such as trademarks, promotion and advertising copy and other alphanumeric information around the circumference of the disk with recorded digital data in the disk's central portion. Such a CD may be a 120 mm CD including a central portion recorded in the 80 mm format of a single CD, with the desired indicia formed by a bright metal indicia-bearing substrate in the 20 mm, radially-extending, circumferential portion of the CD that surrounds the recorded digital data.
Such CD's are manufactured by recording the digital data in the central 80 mm of a 120 mm master, leaving the remaining unrecorded circumferential portion of the master with a smooth surface and applying the desired indicia onto the unrecorded outer peripheral portion of a disk used to form production stampers.
