Description of the Invention (1) The present invention relates to an optical disc recording medium, a manufacturing method and a manufacturing mold thereof, and particularly to a super digital compatible with a digital multi-function disc Multifunctional optical disc, manufacturing method and manufacturing mold thereof. The optical disc is mainly used for storing sound, video and data. Generally, it has only the size of graphics, and its outer diameter is 120 mm or 80 mm. There are two main types of discs, namely CD discs (small discs) and DVD discs (digital versatile discs). CD 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 can also be divided into DVD-Video (Video DVD), DVD-Audio (Audio DVD), DVD-ROM, DVD-R, DVD-RW, DVD-RAM and other formats. DVDs look very similar to regular CDs, with a diameter of 120 mm and a thickness of 1.2 mm. The data storage capacity of DVD can reach 7 to 13 times of CD. Take single-sided single-layer D V D as an example, its data storage capacity reaches 4 · 7GB, more than seven times the storage capacity of a CD. When used in home theater, a single-layer DVD can store at least two hours and fifteen minutes of video images, with high definition image quality (horizontal resolution of up to 500 lines) and high-definition music and interactive multimedia. Performance ° At the same time, the DVD comes with Dolby Digital (AC-3) surround channels and eight independent channels. When applied to audio products, single-sided single-layer DVDs can store six to seven CD players' music content, while providing up to 96 kHz sampling frequency and 24 bit mode conversion capability. As the DVD has a larger paper size, it is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) —i — «.------------- Order -------- -Line (please read the notes on the back before filling this page) -4-497097 A7 B7 V. Description of the invention (2) (Please read the notes on the back before filling this page) High storage capacity when used for storage When playing a game program, the game program can have more unexpected designs, have a stronger sense of reality, and more natural settings, making the game program more entertaining. D v D's read-only storage mode can completely replace the existing CD. Since the capacity of a single-sided single-layer DVD is seven times that of a CD-ROM, only one DVD-ROM disc can store the contents of a reference book, including video, audio, and video clips. Any kind of data can be stored on DvD ', which means that DVD has broad development prospects in multimedia applications. For example, 'Wired and wireless TV can use DVD for more effective programs' Video on Demand (VOD) is an ideal DVD application because DVD images do not need to be rewinded and can be automatically searched. Karaoke DVD is another An application and a huge market. In addition, D V D can also be used in publishing. Other possible application areas include video and audio recording 'to replace tapes in various systems. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in order to keep the DVD with a large capacity while maintaining the appearance similar to that of the CD, the DVD pit (or crater 'pit') is designed to be only half the CD pit That is, 0.4 micrometers, and the track interval distance of the DVD is also half of the CD track interval distance, that is, 0.74 micrometers. In order for the optical head to focus properly on such a small pit, DVD uses a thinner polycarbonate (PC) substrate than CD disks. However, 'if a DVD is made using only a single substrate', the DVD will be too thin to be held smoothly on its own and cannot be played in a conventional DVD player. A conventional DVD player requires that the DVD played must have a minimum thickness of approximately 1.2 mm. Therefore, when manufacturing traditional DVDs, the ―-5- size of this paper applies to the Chinese National Standard (CNS) A4 (210 x 297 mm). The printed clothing of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 497097 A7 ___ B7 V. Description of the invention (3) Using a bonding technique, the rain pad 0.6 mm thick substrates are bonded together to form a 1.2 mm thick DVD. In a single-sided single-layer DVD, there is no recording material on one of the substrates. Obviously, the traditional D V D production process not only wastes the raw materials of the substrate, but also increases the production cost unnecessarily because of the need for expensive bonding machines and a large amount of adhesive. In addition, the bonding process not only prolongs production time, but also reduces D V D yield. The first object of the present invention is to provide a digital multi-function optical disc with a new structure, which is referred to as a super DVD in the description. Super D V D discs have a data format compatible with conventional D V D so they can be played in traditional D V D players, but their manufacturing technology is relatively simple and saves raw materials.
