Abstract
A CD-ROM 201 for recording multi-media information of at least one page stream. Contents of each page stream are successively recorded in the storage areas in the CD-ROM 201. The following three items are shown by the page stream: a partial image list having at least one pair of partial image data which describes partial images of one screen image and display state information including X-Y coordinates, X-Y enlargement rates and a rotational angle showing the display state; control information which describes command to be executed corresponding to an input signal; time line information which describes parameters concerning time sequence processing to be executed corresponding to the control information. The display data creation unit 213 synthesizes partial images shown by the partial image list and creates display data from the partial image data and display state information in the page stream read from the CD-ROM 201, and writes the display data in the display data storage unit 209.
