2 is a flowchart illustrating an embodiment of a method of manufacturing a CD card incorporating an RF IC according to the present invention.

Referring to FIG. 2, the present invention provides a method of engraving a groove in a predetermined position on the front or rear surface of a CD for storing data (S200), attaching a wireless recognition unit including an antenna and an RF IC to the groove (S210), Attaching a protective film to protect from the outside on the wireless recognition unit (S220).

With reference to Figures 1 and 2 will be described in detail the CD card with a built-in RF IC according to the present invention and a manufacturing method thereof.

In this embodiment, in order to attach the wireless recognition unit 120 to the surface of the CD 110 so as not to protrude, a groove (not shown) is below a predetermined depth between the central hole of the CD 110 and the data start area 140. To engrav (S200), and attach the wireless recognition unit 120 to the groove (S210). Here, the central hole has a diameter of 16 mm and the diameter of the data start area is 46 mm based on the central axis of the central hole, but the groove is engraved to 0.4 mm or less in an area of 35 mm or less in diameter based on the central axis of the central hole. It is preferable to attach.

In another embodiment, the wireless recognition unit 120 may be attached between the central hole of the CD 110 and the data start area 140 without engraving the groove. In this case, it is most preferable to attach the wireless recognition unit 120 to a region having a diameter of 35 mm or less based on the central axis of the central hole.

In the above two embodiments, the direct bonding with the antenna 122 with the RF IC 124 being a flip chip so that the size and thickness of the RF IC 124 does not protrude from the surface of the CD 110. To the CD 110. At this time, it is preferable that the antenna 122 uses a printed antenna, an etching antenna, a coil antenna, or the like.

In addition, the RF IC 124 and the antenna 122 may be printed and bonded to the CD 110.

Then, by attaching the protection unit 130 on the wireless recognition unit 120 using an adhesive (S220) to protect the wireless recognition unit 120 from external damage. Here, the protection unit 130 is preferably non-toxic, environmentally friendly material of PVC (polyvinyl chloride), PET (polyethylene terephthalate resin; polyethylene terephthalate resin), or paper, it is preferable to use a polycarbonate. In addition, the protection unit 130 is preferably a doughnut shape of 46mm or less based on the central axis of the central hole.

By attaching a label printed on the advertising content on the back of the CD (110) can obtain an additional promotional effect. It is also possible to print a bar code on the label for other additional services.

When the protection unit 130 is removed from the CD 110, the antenna 122 and the RF IC 124 are disconnected, and thus the transponder function of the wireless recognition unit 120 is lost. This is to prevent reuse of the RF IC 124 or forgery of the CD card 100 by unauthorized users.

In the above description, the case where the RF IC 124 is attached to the inside of the antenna 122 is illustrated as an example as shown in FIG. 1, but the RF IC 124 may be attached to the outside of the antenna 122.

On the other hand, when the wireless recognition unit 120 is attached to the front or rear of the CD 110, if there is a reflective film between the central hole of the CD 110 and the data start area 140, the RF signal is blocked in the rear or front direction do. Thus, a CD using the reflective film of the position where the antenna is to be attached is used.

3 is a perspective view illustrating an example of a CD having a portion of the reflective film 114 removed from a position where an antenna is to be attached when there is a reflective film 114 between a CD central hole and a data start area. In this case, the reflective film is removed in advance before the groove is engraved in step S200 of FIG. 2.

In the embodiment of FIG. 3A, the wireless recognition unit 120 is attached to the front of the CD 110. In the embodiment of FIG. 3B, the wireless recognition unit 120 is attached to the rear of the CD 110. Is shown. Here, the CD 110 includes a layer 112 for storing data, a reflective film 114 made of aluminum, and a protective layer 116.

In FIG. 3, the CD having the reflective film 114 removed by puncturing at regular intervals along the position where the antenna 122 is attached is used, but the CD having the reflective film 114 removed along the circle having the same width as the antenna 122 may be used. It may be. It is most preferable to use a CD in which the reflective film is removed in various shapes along the position where the antenna 122 is attached so that the RF signal can pass through the reflective film and transmit and receive the signal in the opposite direction.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, the present invention, by attaching the RF IC and the antenna to the CD, in addition to the function as a normal data storage medium, using a wireless recognition function, such as traffic card, identity card, student card, book loan, admission ticket, medical card, etc. Can be used in various ways.

In addition, the RF IC and the antenna are attached to the CD so as not to protrude, thereby protecting it from external damage, and using a non-toxic material protection part, which is environmentally effective.

In addition, there is an advantage that can be promoted by attaching a label printed advertising content, to prevent the illegal forgery of unauthorized users by losing the transponder function of the wireless recognition unit when the protection unit is removed.
