Looking now to FIGS. 4A-4C, a cross-sectional view of an optical disk 400 is illustrated in accordance with one embodiment. As an option, the present optical disk 400 may be implemented in conjunction with features from any other embodiment listed herein, such as those described with reference to the other FIGS., such as FIGS. 1-3. However, such optical disk 400 and others presented herein may be used in various applications and/or in permutations which may or may not be specifically described in the illustrative embodiments listed herein. Further, the optical disk 400 presented herein may be used in any desired environment. Thus FIGS. 4A-4C (and the other FIGS.) may be deemed to include any possible permutation.

As shown in FIG. 4A, the optical disk 400 has a thin cross-sectional profile with distinct storage layers 402, 404, 406 extending thereacross. Moreover, FIG. 4C depicts the circular shape of the optical disk 400 along its face 408. However, it should be noted that the thickness t of the optical disk 400 and each of the storage layers 402, 404, 406 have been greatly exaggerated for demonstration purposes. Moreover, each of the storage layers 402, 404, 406 are divided by separator layers which have not been shown.
