A optical storage disk (100)provides multiple logical disks (106,108)without the need to physically alter the structure of the optical storage disk. According to one example embodiment of the present invention, a dual-layer (102-104)data disk is adapted to store data in each of two layers readable by an optical disk reader. A first region (106A-106B) of the disk includes data recorded for a first logical disk, and a second region (108A-108B)is adapted to store data for a second logical disk, and the first and second regions are located on the two layers. Each of the data logical disks includes a lead-in region (106A-108A)and a lead-out region (106A-108D)and for data (106B,108B)therebetween traversing each of the two layers. The lead-out region of the first logical disk (106D)stores pointing data (107)which points to the lead-in region (108A)of second logical disk, and the logical disks are not necessarily physically contiguous. |
