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.
