Abstract
A hybrid optical recording medium is arranged to allow original information that is pre-recorded in a mass manufacturing process to be supplemented by additional information written to the disk after the original information has been recorded using a disk drive. The medium contains a first optical area for storing information which is pre-recorded according to a highly structured standard format and a second optical area in which supplemental information can be written, read back therefrom, erased and changed by a computer connected to the disk drive.
