From a technical point of view, the low anti-counterfeiting level of CDs is an important reason for the proliferation of piracy
At present, most of the electronic labels suitable for disc management on the market are high-frequency (HF) disc labels, and there are also a small number of ultra-high frequency (UHF) disc labels, but these labels are all realized by pasting on the surface of the disc. It is not only inconvenient to implement, but also affects the appearance, and there is a risk of being replaced

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention will be further described.

[0021] figure 1 Shown is a front view structural schematic diagram of the present invention. It can be seen from the figure that the annular UHF electronic tag 2 is embedded in the non-data area outside the central hole 3 of the optical disc 1 , or in other words, the annular UHF electronic tag 2 is embedded in the inner side of the data area of ​​the optical disc 1 . The area between the central hole 3 of the optical disc 1 and the annular UHF electronic label 2 is an annular transparent material area, and the appearance of both sides of the annular UHF electronic label 2 is also covered by transparent materials.

[0022] figure 2 shown, is figure 1 The enlarged schematic diagram of the cross-section along the A-A junction in figure 2 As can be seen in the figure, the optical disc 1 is composed of two sub-discs, the upper sub-disc 1a and the lower sub-disc 1b; in th...

Abstract

The invention discloses an embedded optical disc ultra-high frequency electronic label, which includes an optical disc and its central hole, and is characterized in that: in the non-data area outside the central hole of the optical disc, a ring-shaped ultra-high frequency electronic label is inlaid. Label. The UHF electronic tag is firmly packaged in two discs, and the relevant data in the electronic tag can be easily read within a range of 10cm with an UHF desktop reader, and has good wireless identification performance and anti-counterfeiting function. And, make optical disk have bright appearance, if want to replace this electronic label, then must pry open two sub-CDs, and pry open these two sub-CDs, this CD is also just rotten. Therefore, there is no risk of being replaced. Thereby, the recognition and anti-counterfeiting properties are greatly improved, and due contributions are made to safeguarding the rights of genuine CDs and cracking down on piracy.

Description

technical field [0001] The invention relates to an anti-counterfeit identification device, in particular to an anti-counterfeit identification device for an optical disc. Background technique [0002] As a large-capacity and low-cost data carrier, optical discs still have a broad market in batch-level data storage applications. However, due to the low threshold of optical disc duplication and the lagging protection measures of relevant domestic laws and regulations, pirated optical discs are rampant. From a technical point of view, the low anti-counterfeiting level of optical discs is an important reason for the proliferation of piracy. At present, most of the electronic labels suitable for disc management on the market are high-frequency (HF) disc labels, and there are also a small number of ultra-high frequency (UHF) disc labels, but these labels are all realized by pasting on the surface of the disc. It is not only inconvenient to implement, but also affects the appearan...
