BRIEF DESCRIPTION OF THE DRAWINGS The invention will be more fully understood from the detailed description given hereinbelow and the accompanying drawings. which are given by way of illustration only, and thus do not limit the present invention, wherein: Fig. 1 is a schematic view showing an optical recording medium structure having a memory chip according to a first embodiment of the invention; Fig. 2 is a schematic view showing an optical recording medium structure having a memory chip according to a second embodiment of the invention; and Fig. 3 is a schematic view showing an optical recording medium structure having a memory chip according to a third embodiment of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Fig. 1. an optical recording medium structure having a memory chip is shown. The optical recording medium structure 10 includes an optical recording medium having an inner periphery 12a, an outer periphery 12b, a printed surface 16, an inner ring 14, a memory chip 20 and an antenna structure 22. The memory chip 20 is used to record information, related to manufacturer, seller, protective key, etc., required by users. The information stored in the memory chip 20 can be transmitted to an external reader (not shown) through the antenna structure 22. The above-mentioned optical recording medium can be CD-ROM, VCD or DVD.
The printed surface 16, which is located between the inner periphery 12a and the outer periphery 12b. is a region for pattern design. The inner ring 14 located between the inner periphery 12a and the printed surface 16 is usually made of a transparent material and can also be designed with patterns, but is not used for data recording.
As shown in Fig. 1, the memory chip 20 is directly adhered to the inner ring 14.
If the optical recording medium is a double-sided recording DVD with two layers, the memory chip 20 can be compressed between the upper and lower inner rings (not shown) thereof.
A most commonly used smart card can serve as the memory chip 20. Since the smart card 20 has a large memory capacity, data stored in the smart card 20 can even include product-related data, such as product serial number, product content, and manufacturing data and place, stock management data and a special protective key.
The antenna structure 22 is disposed on the inner ring 14 of the optical recording medium and is electrically connected to the memory chip 20. Like the memory chip 20, the antenna structure is adhered to the inner ring 14. Or, if the optical recording medium is a double-sided recording VCD with two layers, the antenna structure 22 can be mounted between the two inner rings (not shown) thereof.
A reader (not shown) used only for the memory chip 20 can read information stored in the memory chip 20 in coordination with the antenna structure 22.
Interaction between the reader and the antenna structure 22 is performed by contactless electromagnetic (EM) wave transmission. A power supply required by the memory chip 20 can be sensed between the reader and the antenna structure 22. In other words, data stored in the memory chip 20 can be transmitted to the reader through the antenna structure 22 in the form of a contactless electromagnetic wave.
Referring to Fig. 2. an optical recording medium structure having a memory chip according to a second embodiment of the invention is shown. Elements that are the same as those in the first embodiment are labeled with the same reference numerals.
The second embodiment has a structure substantially similar to that of the first embodiment. The main difference is that an antenna structure 22'is adhered or mounted on the outer peripheral 12b of an optical recording medium. Since a memory chip 20 is disposed on an inner ring 14 while the antenna structure 22'is disposed on the outer periphery 12b, it is necessary to use a conductive line 24, such as a metal conductive line, to electrically connect the memory chip 20 and the antenna structure 22'. To avoid signal interference, the conductive line 24 must be mounted on a printed surface 16 of the optical recording medium. As such, undesired signal interference can be efficiently prevented when reading the optical recording medium.
Likewise, data stored in the memory chip 20 can be transmitted to an external reader through the antenna structure 22'. Since the memory chip 20 has a large memory capacity used to store various data, the memory chip 20 can provide product management, anti-piracy and anti-theft functions in the optical recording medium structure.
For a double-sided recording DVD with two layers, since there is no printed surface thereon, the conductive line 24 has to be mounted between the two layers. In this case, there is no signal interference created during data transmission through the conductive line 24.
Referring to Fig. 3. an optical recording medium structure 10 having a memory chip according to a third embodiment of the invention is shown. The optical recording medium structure 10 of the third embodiment is substantially similar to that illustrated in Fig. 1. The main difference between the two embodiments shown in Fig. 1 and Fig.
3 is that an antenna structure 26 is disposed on an inner ring 14 of the optical recording medium structure 10. For example, the antenna structure 26 is adhered to the inner ring 14.
As to the practical efficacy of, for example, the management of the optical recording medium, sellers can record information, such as product serial number, delivery data, and special protective key, on the memory chip 20. A reader used only for the memory chip 20 can read data stored in the memory chip 20. Moreover, data stored in the memory chip 20 can be smoothly read by the reader in a contactless manner, and then transmitted in the form of an electromagnetic wave, even when the optical recording medium structure is completely packaged with a cover. Therefore, the management efficiency of optical recording media products can be greatly improved.
When compared to the optical recording medium described in the prior art which records on an inner ring only information such as product serial number, product content and manufacturing data and place, which information can be read only when the optical recording medium is unpacked, the optical recording medium structure of the invention is more convenient. Additionally, information stored in the memory chip 20 can include more items relating to stock and shipping management.
The memory chip 20 can be a read only memory chip in which all required information is written after the optical recording medium is completely manufactured.
The memory chip 20 can also be a repeatable read/write memory chip in which information can be optionally written.
Furthermore, the memory chip 20 can record a special protective key which is used for anti-counterfeiting. As such, even if the optical recording medium is illegally copied, the counterfeit CDs cannot be read without the special protective key.
Additionally, the counterfeit CDs cannot be read, if a corresponding key is different from a default value. The memory chip 20 can also store data as to whether or not the price has been paid by customers before leaving. In the invention, an appropriate reader can be used to read the memory chip to determine whether or not the price has been paid, thereby providing protection against theft.
As described above, one single memory chip of the invention can simultaneously have a variety of functions which can be achieved only by different methods and technologies in the prior art. Furthermore, the inventive optical recording medium structure displays an industrial utility.
In a word, a first feature of the invention is that a memory chip and an antenna are disposed on an optical recording medium. The memory chip is small in size and has a large memory capacity, such that various data can be recorded according to practical requirements.
A second feature of the invention is that information can be received/transmitted through the antenna even through the optical recording medium structure is already packaged.
A third feature of the invention is that all information related to product management, piracy prevention, protective key, etc., is recorded in the memory chip without need for any other additional methods.
A fourth feature of the invention is that the memory chip is disposed on an inner ring without occupying the recording area of the optical recording medium.
While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment. To. the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
