Combination of an optical-disk and barcode memory medium for use with an optical disk playback apparatus, having control programs stored in the optical-disk and specified by barcodes stored in the barcode memory medium
Abstract An optical-disk playback apparatus 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.
A combination of an optical-disk, a barcode memory medium, a barcode reader and an optical-disk playback apparatus, said optical-disk for being set in the optical-disk playback apparatus and having information recorded thereon including data and plural control programs specifying playback operations of said optical-disk playback apparatus for playing back said data recorded on said optical-disk; said barcode memory medium having barcodes recorded thereon for being read-out by said barcode reader which is electrically connectable to said optical-disk playback apparatus, each of said barcodes including an operation code corresponding to one of said plural control programs specifying one of said playback operations of said optical-disk playback apparatus; and said optical-disk playback apparatus comprising means, responsive to selection of one of said barcodes via said barcode reader, for selecting a corresponding playback operation among said playback operations that corresponds to said one of said barcodes and playing back said data recorded on said optical-disk in accordance with said corresponding playback operation.
