| Abstract: |
An optical-disk playback apparatus is disclosed which plays back an optical-disk on which control programs defining the operations of the optical-disk playback apparatus and other information are recorded. Such optical-disk playback apparatus is operable by a combination of an optical-disk, such as a laser disk or CD, and printed materials on which barcodes are printed. Predetermined programs are recorded defining the operation of the optical-disk playback apparatus corresponding to the barcodes. As a result, variable, complex and yet flexible optical-disk playback operations which are not fixed at the initial system designing stage can be accomplished by simply tracing the printed barcode. The operation of the optical-disk playback apparatus is controlled by the control programs recorded in the optical disk. Difficulties which might occur when an optical-disk and barcode of different systems are combined can be prevented since a one-to-one correspondence between the barcode and the optical disk code is established beforehand.

We claim:
1. An optical-disk playback apparatus for use with an optical-disk adapted to be set in said apparatus and a barcode memory medium, wherein said optical-disk has recorded information thereon comprising first information including control programs specifying operations of said apparatus and second information, and said barcode memory medium has recorded thereon barcodes respectively bearing information corresponding to said control programs, said apparatus comprising:
- playback means for playing back said optical-disk when it is set to said apparatus to derive said recorded information;
- extract means for extracting said first information and said second information from said recorded information derived by said playback means;
- memory means for storing at least said control programs included in said first information extracted by said extract means;
- barcode read means manually operative to read selectively at least one of said barcodes recorded on said barcode memory medium;
- control means connected to said barcode read means, said playback means and said memory means, and including means for operating said playback means to play back said optical-disk when it is set to said apparatus to derive said recorded information and means for receiving said at least one of said barcodes read-out by said barcode read means and selecting one of said control programs stored in said memory means corresponding to said at least one of said barcodes read out by said barcode read means; and
- processing output means, connected to said control means and said extract means, for receiving at least said second information included in said recorded information derived by said playback means and said one of said control programs selected by said control means and processing said second information based on said one of said control programs to be played back by said apparatus.
