ABSTRACT:
Recording areas in an optical disc having a plurality of recording layers allocated so each recording layer includes a data area for recording data, a connection area in which a predetermined pattern of data for indicating that no data area is recorded therein, and a remaining area, wherein a size and location of the data area of each recording layer is determined according to an amount of user data to be recorded. The connection area and the remaining area are allocated next to the data area of each recording layer in a direction from the inner circumference to the outer circumference of the disc. Accordingly, a recording time is reducible, and exclusive areas for recording information except user data can be additionally allocated to outer circumference areas of the optical disc or the sizes of the exclusive areas can be increased, increasing recording medium efficiency.
