The optical recording medium has an inner periphery, an outer periphery, a printed surface and an inner ring, the printed side being between the inner and outer peripheries, and the inner ring lying between the inner periphery and the inner periphery. on the printed side. The memory chip is glued or mounted on the surface of the inner ring of the optical recording medium. The antenna structure is also disposed on the surface of the inner ring of the optical recording medium and is electrically coupled to the memory chip. By the antenna structure, the information stored in the memory chip can be transmitted in good conditions to an external reader. Because the memory chip has a large memory capacity used to store various pieces of information, the memory chip can provide product management, hacking prevention and anti-theft functions in the support structure of the memory chip. optical recording of the invention.

In addition, another optical recording medium structure having a memory chip according to the invention comprises an optical recording medium, a memory chip, an antenna structure, and an optical recording medium. and a conductive line. The optical recording medium has an inner periphery, an outer periphery, a printed surface and an inner ring. The printed surface is between the inner and outer peripheries. The inner ring is between the <B> p </ B> inner riphery and the printed surface. The memory chip is glued or mounted on the surface of the inner ring of the optical recording medium. The antenna structure is glued or mounted on the outer periphery of the optical recording medium. The conductive line is mounted on the printed surface. In addition, the antenna structure is electrically connected to the memory chip by the conductive line. With the antenna structure, the information stored in the memory chip can be transmitted to an external reader.

Similarly, because the memory chip has a large memory capacity used to store various pieces of information, the memory chip can provide product management, hacking prevention and anti-theft functions in the structure. optical recording medium of the invention.

The invention will be better understood by reading the following detailed description of embodiments, given as non-limiting examples. The remainder of the description refers to the accompanying drawings, in which: <B>: <B> 1 </ B> is a schematic representation showing an optical recording medium structure having a memory chip According to a first embodiment of the present invention, FIG. 2 is a schematic representation showing an optical recording medium structure having a chip of <I> m </ I>. moire conforming to a second embodiment of the invention; and Figure <B> 3 </ B> is a schematic representation showing an optical recording medium structure having a <I> compliant chip <B> to </ b> a third mode Embodiment of the invention Referring to <B> 1, <B> 1, an optical recording medium structure having a memory chip is shown. The optical recording medium structure <B> 10 </ B> comprises an optical recording medium having an inner periphery 12a, an outer periphery <B> 12b, </ B> a printed surface <B> 16 , An inner ring 14, a memory chip 20 and an antenna structure 22. The memory chip 20 is used to record information about a manufacturer, a vendor, a protection key, etc. ., which is required by users. The information stored in the memory chip 20 may be transmitted to an external reader (not shown) via the antenna structure 22. The optical recording medium mentioned above may be of the CD-type. ROM, VCD or DVD.

The printed surface <B> 16, </ B> which lies between the inner periphery 12a and the outer periphery <B> 12b, </ B> is a region intended to receive patterned patterns. The inner ring 14 between the <B> p </ B> inner rim 12a and the printed surface <B> 16 </ B> is usually made of a transparent material, and it can also receive patterns drawn, but it is not used for recording data.

As shown in FIG. 1, the memory chip 20 is directly glued to the inner ring 14. If the optical recording medium is a double-sided DVD with two layers, the memory chip 20 may be interposed between its upper and lower inner rings (not shown).

A very commonly used chip card can be used for the memory chip 20. Because the chip card 20 has a large memory capacity, the data stored in the chip card may even include product related data, such as a product serial number, product content, and manufacturing data as well as location management data. and stock, and a special protection 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 structure of the Antenna is bonded to the inner ring 14. Alternatively, if the optical recording medium is a double-sided VCD, with two layers, the antenna structure 22 can be mounted between its two inner rings (not shown).

A reader (not shown) used only for the memory chip 20 can read the information stored in the memory chip 20 in association with the antenna structure 22. The interaction between the reader and the antenna structure 22 is accomplished by electromagnetic wave (EM) transmission without contact. Power supply required by the memory chip 20 may be transmitted between the reader and the antenna structure 22. In other words, data stored in the memory chip 20 may be transmitted to the reader by the intermediate of the antenna structure 22 in the form of a tromagnetic electromagnetic wave, without contact.

Referring to FIG. 2, there is shown an optical record carrier structure having a memory chip conforming to a preferred embodiment of the invention. The elements which are the same as those of the first embodiment are designated by 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 glued or mounted on the outer periphery <B> 12b </ B> 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 <B> outer board <b> 12b, </ B> it It is necessary to use a conductive line 24, such as a conductive metal 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 <B> 16 </ B> of the optical recording medium. In these conditions, any harmful signal interference can be effectively avoided during the reading of the optical recording medium.

Similarly, data recorded in the memory chip 20 may be transmitted to an external reader via the antenna structure 22 '. Because the memory chip 20 has a large memory capacity used to store various data, the memory chip 20 can perform product management, piracy prevention, and antitheft functions in the media support structure. optical recording.

For a double-sided, two-layered DVD, since this disk does not have a printed surface, the conductive line 24 must be mounted between the two layers. In this case, no signal interference is produced during data transmission by the conductive line 24.

Referring to <B> 3, <B> 3, </ B> we see an optical record carrier structure <B> 10 </ B> having a <B> compliant memory chip to </ B> a third embodiment of the invention. The optical record carrier structure <B> 10 </ B> of the third embodiment is substantially similar to the <B> 1 </ B> one. The main <B> diff <-> </ B> between the two embodiments shown in Figure <B> 1 </ B> and Figure <B> 3 </ B> is that a structure of antenna <B> 26 </ B> is arranged on an inner ring 14 of the recording support structure opti <B> 10. </ B> The antenna structure <B> 26 </ B> is example glued on the inner ring 14.

With regard to practical efficiency, for example in the management of the optical recording medium, sellers can register in the memory chip 20 such information as a product serial number, delivery data and a special protection key. A reader used only for the memory chip 20 can read the data recorded in the memory chip 20. In addition, the data stored in the memory chip 20 can be read under good conditions by the reader, without contact, and can then be emitted as an electromagnetic wave, even when the optical recording medium structure is fully packaged, with a cover. The product management efficiency of optical recording media can therefore be greatly improved.

In comparison with the optical recording medium described in the prior art, which records on an inner ring only information such as a product serial number, a product content and manufacturing data and a location, this information Although it can be read only when the optical recording medium is not packaged, the optical recording medium structure of the invention is more convenient. In addition, the information stored in the memory chip 20 may include more items relating to inventory and delivery management.

The memory chip 20 may be a ROM chip in which all the required information is written after the optical recording medium has been fully fabricated. The memory chip 20 may also be a memory chip with repeatable read / write capability in which information may be written as desired.

In addition, the memory chip 20 can register a special protection key which is used for the prevention of counterfeiting. Thus, even if the optical recording media is copied illegally, counterfeit CDs can not be played without the special protection key. In addition, counterfeit CDs can not be played if a matching key is different from a default value. The memory chip 20 can also record data indicating whether customers have paid the price or not before going out. In the invention, an appropriate reader can be used to read the memory chip, so as to determine whether the price has been paid or not, which provides protection against theft.

As described above, a single memory chip in accordance with the invention can simultaneously have a variety of functions that can be obtained in the prior art only by different methods and techniques. In addition, the optical recording medium structure of the invention has an industrial utility.

In a nutshell, a first feature of the invention is that a memory chip and an antenna are disposed on an optical recording medium. The memory chip has a small size and a large memory capacity, so that various data can be recorded according to practical requirements.

A second feature of the invention is that information can be received / transmitted via the antenna, although the optical recording medium structure is already <B> already </ B> .

A third feature of the invention is that all information concerning product management, prevention of misfacing, a protection key, etc., is recorded in the memory chip without the need for other methods. any additional.

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.

It goes without saying that many modifications can be made to the device described and shown, without departing from the scope of the invention.
