A data disc, on which there are recorded main text data including map data for displaying a picture, map data pointer information as pointer information for the map data, item data for retrieving the main text data, display position data indicating the display position of the item data on a display screen, and address data for reading out data corresponding to different items. The data disc is reproduced so that the map data are read out from the disc at the same time that the item data are displayed in superimposition on the display screen at a position indicated by the display position data of the read-out map data, and output data corresponding to the item data are read out from the main text data on the basis of the address data for unifying the data recording format and retrieval method to enable reciprocal retrieval of the letter data, map data and voice data.
An optical disc for enabling reciprocal retrieval by an optical disc reproducing apparatus, the optical disc having digitally recorded thereon main text data composed of text data, image data, and audio data in a CD-ROM XA format and management data, said management data at least including image data pointer information for representing an image to be displayed by the optical disc reproducing apparatus, item data for designating and retrieving the main text data, display position data for representing a display position for the item data on a display screen of a display means of the optical disc reproducing apparatus, and address data for representing and reading out the main text data, corresponding to the item data, read out and displayed on the display means.
A data retrieval method for an optical disc, the optical disc being digitally recorded with main text data composed of text data, image data and audio data in a CD-ROM XA format and management data, the management data at least including image data pointer information for representing the image data for displaying a picture on a display screen, item data for designating and retrieving the main text data, display position data for representing a display position of the item data on the display screen and address data for representing and reading out the main text data corresponding to the designated item data, the method comprising the steps of:
An information retrieval and display system for allowing reciprocal retrieval of text digital data, image digital data and audio digital data comprising:
