Description

  The present invention relates to a recording medium in which a game program, a music program, and the like are written and becomes a product of a distribution service for sale and purchase, and a manufacturing method thereof.

  Various prepaid cards such as public telephones are in circulation, but this type of prepaid card can be used / unused by punching a punch hole when it is used or by cutting a part of the card. Use etc. are prevented (for example, patent document 1).

  On the other hand, the following distribution services using recording media have also been proposed. In other words, this distribution service can be used with a distributor who sells recording media consisting of various optical discs such as CD-ROM, CD-R, DVD, etc. This is a service in which unused recording media collected by the take-out trader is distributed to the seller, and the unused record media is circulated and distributed among the seller, customer, and take-off trader. .

  By the way, in the case of the prepaid card as described above, a method of directly making a hole in the card or cutting a part thereof is used to distinguish between unused and used, but in the case of the above optical disk, a hole is made. The general-purpose drive device does not have a means for cutting and is not common.

  In addition, the optical disc is not provided with an identification information section for writing the seller's identification information or a means for confirming the usage state. Therefore, the optical disc cannot be effectively used for the above distribution service as it is. Therefore, there has been a demand for a recording medium composed of an optical disc that is suitable for recording and can be reproduced by a general-purpose drive device.

  Therefore, the present applicant combines an optical disc and a wireless (so-called RF) data carrier using radio waves (for example, microwaves), and sells information such as the seller's identification information and sales date / time to this data carrier. In some cases, a recording medium has been proposed in which the position and method of attaching the data carrier to the optical disc is devised so that the function of the data carrier must be physically destroyed when writing and program playback of the optical disc. .

For example, as shown in FIG. 5, a data carrier is formed by attaching and fixing a sheet 3 made of an insulating material on the disk surface of the optical disk 1 so as to hold the data carrier 2 and close the center hole 11 of the optical disk 1. The two chip portions 20 are disposed within the range of the center hole 11, and the antenna portion 22 connected to the chip portion 20 is disposed on the disk surface around the center hole 11, and the center hole 11 is closed. A plurality of cuts 7 for cutting out parts of the sheet 3 are provided on a circumferential line substantially concentric with the center hole 11, and when the part of the sheet 3 corresponding to the center hole 11 is cut out by the cuts 7, the antenna part 22 and the chip part 20 are arranged. The lead wire portion 21 to be connected is cut, and the chip portion 20 is removed from the optical disc 1 together with the cut-out portion of the sheet 3. So that can be separated. That is, the data carrier 1 is physically destroyed and does not function, and the optical disc 1 is not blocked by the center hole 11 and can be reproduced by the drive device.
Japanese Unexamined Patent Publication No. 2000-182015 (FIG. 1)

  By the way, in the case of the configuration as described above, when the cut 7 is punched in the sheet 3 while holding the data carrier 1, the thin lead wire portion 21 may be cut, resulting in a defective product. was there. In order to eliminate this fear, it is necessary to increase the drilling accuracy so that the lead wire portion 21 is not cut when the cut 7 is drilled.

  The present invention has been made in view of the above points, and the object of the present invention is to reduce product defects due to cutting of the lead portion of the data carrier at the time of drilling the cut without increasing the drilling accuracy of the cut. Another object of the present invention is to provide a recording medium and a method for manufacturing the same that can reduce the manufacturing cost because high punching accuracy is not required.

And an insulating sheet that is fixed to the disk surface of the optical disc so as to close the center hole of the optical disc, and the sheet is substantially abbreviated as the center hole. A plurality of holes are formed on a concentric circumference with predetermined intervals, and the data carrier has a chip portion disposed in a center hole range and an antenna portion connected to the chip portion disposed in a range of the disk surface. A lead wire portion connecting the antenna portion and the chip portion is cut across the circumferential line of the sheet. In a recording medium that is free, the portion of the lead wire portion that crosses the cut is configured by a plurality of lines that are connected in parallel to each other and the interval between the cuts is equal to or greater than the width of the line. It is characterized by.

  According to the first aspect of the present invention, when the cut line is drilled on the circumference, it is possible to leave at least some lines of the lead portion of the data carrier without being cut by the cut line. As a result, it is possible to prevent the chip part and the antenna part from being separated from each other, resulting in a product defect. As a result, the product defect is reduced, and it is not necessary to improve the perforation accuracy of the cut. Since the manufacturing cost can be reduced and the width of each line can be reduced, when the part surrounded by the cut is cut, almost no burrs are generated at the cut part of the line. There is almost no burr that faces the center hole when playing an optical disc mounted on the drive device, so there is no concern about trouble occurring when the drive device is installed. .

  According to the invention of the recording medium manufacturing method of claim 2, in the recording medium manufacturing method of claim 1, the recording of the optical disk is performed so that the center hole of the optical disk is closed with an insulating sheet holding the data carrier in advance. A first step of fixing to the disk surface opposite to the reading surface; a second step of fixing a cover label to the disk surface of the optical disc so as to cover the sheet after the first step; After the second step, the method includes a third step of providing a plurality of cuts on the circumferential line substantially concentric with the center hole so as to freely cut off the portion of the cover label and the sheet closing the center hole. It is characterized by.

  According to the invention of claim 2, since the cut is perforated while the insulating sheet holding the cover label and the data carrier is fixed to the medium, the insulating sheet and the cover label are stably held during the perforation. Since the optical disk itself can be used as a member for the recording, the punching process can be easily performed, and the recording medium can be manufactured without using an expensive facility for punching by separately preparing a means for stably holding the cover label. .

  According to the invention of the recording medium manufacturing method of claim 3, in the recording medium manufacturing method of claim 1, the insulating sheet holding the data carrier in advance is applied to the portion of the cover label corresponding to the center hole of the optical disk. A first step of fixing, and a cut line that cuts off the portion of the cover label and the sheet that closes the center hole of the optical disk after the first step, on a circumferential line along the outer peripheral edge of the portion to be cut A plurality of second steps are provided, and after the second step, the cover label is fixed together with the sheet on the disk surface opposite to the recording / reading surface of the optical disk so that the center hole is closed by the sheet. It consists of a 3rd process, It is characterized by the above-mentioned.

  According to the third aspect of the present invention, since the cut is made in the sheet holding the cover label and the data carrier before being fixed to the optical disc, the cover label and the sheet can be used even if a trouble due to the cut processing occurs. As a result, it is possible to eliminate product defects including optical disks.

  The present invention can leave at least some lines of the lead portion of the data carrier uncut by the cut when punching the cut on the circumference, and therefore the antenna portion and the chip of the data carrier when cutting the cut. As a result, product defects are reduced, and it is not necessary to increase the drilling accuracy of the cuts. Therefore, the drilling operation is facilitated, and the manufacturing cost is reduced accordingly. In addition, since the width of each of the lines can be reduced, almost no burrs are generated at the cut part of the line when the part surrounded by the cut line is cut off. Recording media that does not have to worry about troubles when installing the drive device because there is almost no burrs that face the center hole when playing with it mounted. Providing can, also it can be produced with an improved yield by eliminating or can be produced, or the occurrence of product defects without expensive equipment.

A plurality of perforations are made on the circumference along the line. After the second step, in the third step shown in FIG. 4D, the sheet is placed on the disc surface opposite to the recording / reading surface of the optical disc 1 so that the center hole 11 of the optical disc 1 is closed by the sheet 3. 3 and the cover label 5 are pasted and fixed using the pressure-sensitive adhesive layers 6 and 4 (see FIG. 1). As a result, a desired recording medium M is completed. Even in the case of this example, by setting the interval between the cuts 7 to be larger than the width of the line 21a, the entire line 21a is prevented from being cut when the cut 7 is drilled, and the antenna unit 22 and the chip are cut through the uncut line 21a. The occurrence of product defects is prevented by ensuring electrical connection with the unit 20.

  In each of FIGS. 4A to 4D, the upper drawing shows a top view and the lower drawing shows a side sectional view.

  Next, a distribution service using the recording medium M of the present invention will be briefly described.

  First, in the distribution service, when the seller sells the recording medium M, the writer device performs a process of writing identification information such as the seller and sale date and time on the data carrier 2. When a purchaser who has purchased the recording medium M from a dealer or a person who has been given by the purchaser wants to play and enjoy the game program or music program recorded on the recording layer of the recording medium M, first of all, the cut is made. 7 is used to cut out the corresponding portions of the sheet 3 and the cover label 5 in the center hole 11 to expose the center hole 11. Thus, if the recording medium M is set in the drive device in the same manner as a normal optical disc, the program recorded on the recording layer of the optical disc 1 can be reproduced and enjoyed.

  On the other hand, when the above-described sheet 3 and cover label 5 are cut out for program reproduction, the chip part 20 of the data carrier 2 is removed from the optical disk 1 in a form separated from the lead wire part 21, so the chip part 20 is removed. Even if the customer takes the recording medium M to the take-out agent, it can be seen at a glance that the recording medium M has been used, and the mistake that the take-out agent takes over (buys) the used recording medium M can be avoided. .

  That is, the customer substantially purchases the recording medium M by reproducing the program. Even if the part including the chip part 20 that has been extracted despite being used is fitted into the extracted part and disguised as an unused state in appearance, the cut lead parts 21 and 21 are not seen through in appearance. Since the identification information written on the data carrier 2 by the reader device cannot be read by the reader device, it can be easily detected that the recording medium M has been used. Thus, it is possible to prevent the used recording medium M from being taken over (purchased). In addition, the forged storage medium M can be detected by reading the record information of the data carrier 2.

  Now, if you have purchased a recording medium M from a distributor, but you want the recording medium M of another program or you no longer need it, the customer will collect the recording medium M from the distributor (buyer) for a specified fee. It is possible to buy (buy) or exchange for equivalents in the distribution service.

  In other words, the customer only needs to take the unused recording medium M to the take-out trader, and the take-out trader confirms whether the brought-in recording medium M is unused or not, and is further recorded on the data carrier 2 by the reader device. The identification information is read out, and based on the identification information, it is determined that the recording medium M is a product to be purchased, and the recording medium M is purchased at a predetermined fee or is exchanged for an equivalent. In this case, it is also determined from the identification information whether the seller is in a business relationship with the take-off agent, and the elapsed date and time from the sales date is determined, which is used for determining the charge according to the elapsed date and for refusal of collection. To do. The take-out trader can recirculate the recording medium M as a product for distribution by reselling the collected (purchased) recording medium M to the seller.
