Abstract
A code pattern of an information recording medium contains processing information necessary for editing data according to a restoration processing procedure for restoring multimedia information. The restoration processing procedure has a hierarchical structure of layers 1 to 5. The layer 5 has a file management function. The layer 4 has a function of collecting subset elements to create a subset and converting the same to create a data transfer unit or sector which the layer 5 deals with. The layer 3 or lower layer has a function of reading the code pattern from the information recording medium, subjecting the code pattern to a preset restoration process and outputting the subset elements.
