Abstract: An optical disc has a data disc, a transparent disc to enclose and protect the data disc and an annular control chip securely attached to the clamping area of the transparent disc. The control chip records the data area allocation. Consequently, the data area allocation written in the control chip will not be copied by conventional copying techniques. An infringing disc will not work even when all of the data files on the data disc are completely copied. Therefore, a good security is provided, and infringement can be avoided. In addition, the optical disc can work as a smart card after bonding with a chip on it. The function of the optical disc can be improved.
