Abstract
There are provided on an optical disk a high resolution image file for storing a high resolution image data, an index file for storing a predetermined number of low resolution image data, a management file for storing information about the high and low resolution image data, and a management data table for controlling the relative locations of the high resolution image file and index file to each other on the optical disk. A playback apparatus according to the present invention plays back the index file through referring to data of the management file and management data table and produces on a monitor a single screen display of the predetermined number of the low resolution image data saved in the index file. Accordingly, the predetermined number of the low resolution image data can be read out by a single access action thus speeding up the display of index images.
