Embodiment Construction

[0024] The basic principle of the present invention is to place two optical disc masters overlappingly under the heavy particle radiation source, and deposit them on the optical disc master instantaneously through the bombardment of heavy particles, thereby forming the same nanometer on the contact surface of the two optical disc masters. Track random information, and then transfer the information to the disc, and after processing and interlocking encryption with software, it is more effective to prevent the disc from being pirated.

[0025] refer to figure 1 The structure of an anti-piracy optical disc according to the present invention will be described. The CD master includes three parts: a nano-track inspection area 1, a nano-track digital information encryption area 2, and an application software data area 3. The sector address of the nano-track inspection area 1 in the optical disc is specific, and application software data is no longer recorded in this area during the ...

Abstract

The present invention relates to a method for enciphering optical disk by using nano track and antipiracy optical disk made by using said method. The basic principle of said invention lies in that itutilizes bombardment of heavy particle and mementary deposition on the mother plate of optical disk to form random information with identical nano track on the contact surface of two optical disk mother plates, then utilizes the Fourier transform method to process said information and make secondary encryption of said information, finally makes it and applied software data form on optical disk together. Said invention can effectively prevent optical disk from pirating.

Description

technical field [0001] The invention relates to a method for preventing piracy of optical discs, in particular to a method for preventing optical discs from being pirated by combining nanometer track technology and software encryption technology to realize interlocking, and at the same time relates to an anti-piracy optical disc manufactured by the method. Background technique [0002] At present, digital information storage products including computer software, audio-visual products and books have become more and more popular, and the development of digital information storage products involves various fields of life and national economy. Optical disc is a major digital information storage product, which is characterized by large storage capacity and low production cost. But existing optical disc manufacturing technology makes it extremely easy to be copied. The phenomenon of CD piracy is very serious, and the problem of preventing CDs from being pirated is increasingly ur...
