Abstract: The present invention facilitates identification of whether or not an optical disc is a optical disc of which recording capacity is enlarged. A synchronization pattern of ATIP information embedded into guide grooves irradiated with a light spot is made to be different between a high density optical disc and a standard density optical disc of which recording capacity is not enlarged. Specifically, while the synchronization pattern of the standard density optical disc is preferably made into "3T+1T+1T+3T" (where "T" represents a minimum channel bit of a signal obtained by reading a positional information), the synchronization pattern of the high density optical disc is preferably made into "3T+3T+1T+1T" for example. By reading the ATIP information and recognizing the synchronization pattern thereof, it can be easily and quickly identified whether the optical disc has a standard density or a high density.

Abstract: THE OBJECTIVE OF THE PRESENT INVENTION IS TO FACILITATE TO IDENTIFY WHETHER OR NOT THE OPTICAL DISC (10) IS A OPTICAL DISC OF WHICH RECORDING CAPACITY IS ENLARGED.A SYNCHRONIZATION PATTERN OF ATIP INFORMATION EMBEDDED INTO GUIDE GROOVES (PG) IRRADIATED WITH A LIGHT SPOT IS MADE TO BE DIFFERENT BETWEEN A HIGH DENSITY OPTICAL DISC AND A STANDARD DENSITY OPTICAL DISC OF WHICH RECORDING CAPACITY IS NOT ENLARGED. SPECIFICALLY, WHILE THE SYNCHRONIZATION PATTERN OF THE STANDARD DENSITY OPTICAL DISC IS MADE INTO "3T +1T +1T +3T" (WHERE "T" REPRESENTS A MINIMUM CHANNEL BIT OF A SIGNAL OBTAINED BY READING A POSITIONAL INFORMATION), THE SYNCHRONIZATION PATTERN OF THE HIGH DENSITY OPTICAL DISC IS MADE INTO "3T+3T+1T+1T" FOR EXAMPLE. BY READING THE ATIP INFORMATION AND RECOGNIZING THE SYNCHRONIZATION PATTERN THEREOF, IT CAN BE EASILY AND QUICKLY IDENTIFIED WHETHER THE OPTICAL DISC (10) HAS A STANDARD DENSITY OR A HIGH DENSITY.(FIG 12)

Abstract: PHYSICAL ADDRESSES OF THE RECORDING AREAS PROVIDED ON AN OPTICAL DISC ARE REPRESENTED IN A TIME-AXIS DATA FORMAT AND IN A BINARY DATA FORMAT. THE PHYSICAL ADDRESS VALUE GRADUALLY INCREASES FROM THE INNER PART OF THE DISC TO THE OUTER PART OF THE DISC, WHILE THE FORMATS REMAIN IN ONE-TO-ONE CORRESPONDENCE OVER THE RECORDING AREAS. THE DISTANCE THE OPTICAL HEAD (24) MUST MOVE TO REACH A TARGET RECORDING AREA CAN THEREFORE BE CALCULATED EASILY INDEPENDENTLY OF WHERE ON THE DISC THE OPTICAL HEAD (24) IS LOCATED, ENABLING THE OPTICAL HEAD (24) TO QUICKLY ACCESS THE TARGET RECORDING AREA.
