Abstract:
A multimedia optical disk contains a data area for recording a plurality of objects. The data area is composed of a plurality of small areas and one object is recorded over continuous small areas and each small area contains first and second subareas. Animation data in a unit of a prescribed period of time and auxiliary video data to be reproduced simultaneously with the animation data are recorded in the first subarea and the auxiliary video data are a menu picture containing a plurality of buttons used for choosing between various display modes. Control information is recorded in the second subarea and the control information contains button control data required for responding to the operation of the user when the menu picture in the first subarea in the same small area is to be reproduced and supplementary control data for operating the menu for the user. When the optical disk is constituted in such a way, the response and the interactive feature of the disk can be improved, because the disk can be controlled on a small area basis. In addition, since the operation of the user can be executed by using the supplementary control data for each small area, the interactive reproduction advancing performance can be improved.
