PROBLEM TO BE SOLVED: To provide an information processing and a corresponding optical disk capable of reproducing information respectively recorded on a land and a groove without a pause. SOLUTION: The information processing device imparts a logical address capable of changeing over a land and a groove to every zone divided by making prescribed number of blocks as unit to physical addresses inherent in an optical disk. Consequently, a lens actuator positioned at the block having the physical address 0 of the land of a zone 1 is moved to the block having the physical address 10000 of the groove of the zone 1 next to the block having the physical address 9 and is guided to the physical address 10009 of the groove of the zone 1 and further, is moved to the block having the physical address 10 of the land of a zone 2. Subsequently, information are reproduced in the order of the groove of the zone 2, the land of a zone 3 and the groove of the zone 3. |
