Description

470943 Printed by A7 B7, Consumer Cooperative of Employees of Intellectual Property Bureau, Ministry of Economic Affairs V. Description of the Invention The present invention relates to smart cards and optical disc recording media, and particularly to a composite smart optical disc card composed of a combination of smart cards and optical disc recording media, Manufacturing method of composite smart disc card. BACKGROUND OF THE INVENTION Smart cards are similar in shape and size to credit cards. Technically, smart cards can be classified into chip cards and contactless cards. An electronic microcontroller is embedded inside the chip card, allowing more important data to be stored, as well as shielding the memory area from being inaccessible for optimal security performance. The chip card can be used as a credit card, mobile phone card, parking card, health card, electronic shopping card, and so on. Contactless card is a new type of chip card. Data is transmitted between the contactless card and the external circuit by radio frequency. Contactless cards can be used as public transportation cards, access control cards, etc. Optical discs are mainly used for storing sound, video and data. Generally they have a circular size with an outer diameter of 120 mm or 80 mm. There are two main types of optical discs, namely CD discs (small discs) and DVD discs (digital versatile discs). CD discs can be divided into cd-DA, CD-I, CD-Photo, CD-G, CD_ROM, CD-ROM XA, VCD, CD_R, CD-RW and other formats according to various functions and recording formats. DVD discs can also be divided into DVD-Video (video DVD), DVD_Audio (audio DVD), DVD-ROM, DVD-R, DVD-RW, DVD-RAM and other formats. Conventional optical discs have such a layered structure, and the bottommost layer is a polycarbonate substrate, and above it are a data recording layer, a metal thin film layer, and a varnish layer. This optical disc is made by the following process. First make a circular substrate; however, this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -4- — — — — — — — — — 1111111 «—— — — — — I— (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 470943. ^, A7 ____B7___ • 5.
