Abstract:
A consumer is provided with an implementation to personalize his compact optical recording discs. A compact optical recording disc comprising a primary section including a read-only permanent digital data recording, and an ancillary read-write section enabling a user to digitally record data to thereby personalize the recording disc to the needs of the user. The section including the read-only permanent digital recording is on a spiral track on said recording disc, and the read-write section is on a spiral track extension continuous with the continuous track. The read-only spiral track comprises a layer of sequential bumps defining the permanent digital data recording pattern, and the read-write spiral track extension comprises a smooth layer of laser beam sensitive material, the material reversibly darkens upon exposure to define the digital data recording pattern.
