Abstract:
1. A method of reproducing data from a plurality of recording layers of an optical recording medium, each of the recording layers comprising a user data area, a connecting area, and a remaining area, the method comprising: reproducing user data recorded in the user data area of each of the recording layers; wherein in each of the recording layers, the user data area has an outer boundary that was determined according to an amount of data that was recorded on the optical recording medium; in each of the recording layers, locations of the connecting area and the remaining area were determined according to the determined outer boundary of the user data area; in each of the recording layers, the user data area, the connecting area, and the remaining area are sequentially arranged in a direction from an inner circumference of the optical recording medium to an outer circumference of the optical recording medium so that the connecting area is after the user data area in the direction, and the remaining area is after the connecting area in the direction; in each of the recording layers, the remaining area comprises an exclusive area for a specified purpose, an unused area, and a buffer area; in each of the recording layers, a usage direction of the exclusive area is different from a usage direction of the user data area; and in each of the recording layers, the connecting area stores predetermined data.
