Description of the invention (1) (1), [Technical field to which the invention belongs] The present invention relates to an optical recording medium and its manufacture. A digital video and audio disc with an improved printing form and its manufacturing method are particularly (2), [previously Technology] With the advancement of science and technology, the use of optical disc recording media for storage is an increasingly popular data storage method. At present, the most common light wind second warp bodies include CD (Compact Disc), digital video disc 1 δ, and digital media Versatile Disc. Among them, because the digital D 'data storage capacity is much larger than the CD data storage capacity, The second disc can be said to be the mainstream of future optical recording media. ~ 9 light Please sign as shown in Figure 1. The conventional digital video disc includes one disc 11 and one second half disc 12. Among the music half, the thickness of the first half disc 11 and the second half disc 12 is 0.6 mm, so the digital video and audio produced by bonding the first half disc u and the second half disc 12 are bonded. The thickness of the optical disc is 12 coffees. For example, half of the disc 11 is composed of a plurality of layers of materials. Generally, the first half of the disc 11 mainly includes a substrate and a reflecting layer. It should be noted that if the digital video light is a recordable or rewritable digital video disk, the first half of the disc ^ ... The fine structure may include a substrate, a recording layer (Dye), and a reflective layer. A bang is a substrate, a down-dielectric layer, a recording layer, an up-dielectric layer, and a reflective layer (not shown in the figure 1221612. V. Description of the invention (2) ). In addition, the two second half discs 12 are mainly composed of a blank substrate. In digital video discs that are common at 2%, they usually have a reading side and a printing side; as shown in the figure, half of the discs have a reading side 111 and a first bonding surface 112.

Description of the Invention (4) — In the example, Chu, brother—half disc 31 is attached to the second half disc 32. Among them, the thicknesses of the first and second discs 31 and 32 are all 0.6 mm, and the thickness of the digital video light j 3 is ι. 2 mm. The first half-disc 31 has a reading surface 311 and a first bonding surface 312, and the Jing take surface 3 1 1 is opposite to the first bonding surface 3 1 2. It should be noted that the first half disc 31 may be a half disc of DVD, a half disc of DVD-R / RW, a half disc of DVD + R / RW, a half disc of DVD-RAM, etc. As an example, the half-disc 31 includes a substrate and a reflective layer (not shown), and a plurality of pits are formed in the substrate. The second half of the disc 3 2 has a second and second bonding surface 321, which is used to be bonded to the first bonding surface 3 1 2; the second half of the disc 32 has a pattern display surface 3 2 2 ' The second bonding surface 3 2 1 is opposed to each other. In this embodiment, the first half disc 32 is composed of a substrate 3 2 3, and one side of the substrate 3 2 3 facing the second bonding surface 3 2 1 is formed with a pre-engraved printing pattern 3 2 4. Therefore, when the second half disc 32 is viewed from the pattern display surface 3 2 2, a pre-engraved printed pattern '3 24 can be observed. It should be noted that the substrate 3 2 3 is formed by an injection molding process, and the pre-engraved printed pattern 3 2 4 is formed during the injection molding process. In addition, a pre-printed pattern may be formed on one side of the substrate facing away from the second bonding surface (not shown). As described above, the first bonding surface 31 2 of the first half-disc 31 and the second bonding surface 3 2 1 of the second half-disc 32 are bonded to form a digital video light ^ 3. ^ In this embodiment Among them, one side of the digital video disc 3 is a pattern display surface 322, and the other side thereof is a reading surface 3 1 1. In addition, 'the second half of the disc 3 2 may be composed of a substrate and a reflective layer 1221612 V. Description of the invention (5) (not shown in the figure), at this time, the substrate north ac case display surface 3 2 2 and The side of the substrate facing the reflection \ reflection layer is the pre-engraved printed figure 帛 324; the reflection = -side is formed with a complex. In the present embodiment, when the first stone is covered with a pre-engraved printing pattern 324, the second digital video disc = two p and the second half disc 32 are bonded to each other, and the reading side 311 /面 1 surface is the pattern display surface 3 2 2, which is to make it easier to explain the content of the present invention according to the preferred embodiment of the present invention. Refer to Figure 4 for the flow of the digital shirt audio CD manufacturing method. Referring to FIG. 4, the manufacturing method of the DVD includes a substrate forming process, the “digital video and audio program of the embodiment. The board production order, a sputtering process, and A laminating private mountain Ϊ In the embodiment, the 'substrate molding procedure is to use # to make a molding process to form a required substrate, such as the aforementioned substrate 3 2 3, or the first: half disc 3 1 Substrate. It should be noted that, when carrying out the substrate forming process, a corresponding stamper must be made by laser engraving technology according to the required substrate. For example, if the required one is the aforementioned one, The substrate 3 2 3, that is, it has a groove with a pre-engraved printing pattern of rp R 〇 D 丨 sc ", the master is a protrusion with the word" PRODISC ", so the pre-engraved printing pattern is in the injection molding process In addition, if the required one is the substrate of the first half-disc 31, the master system has a plurality of protrusions so as to form a plurality of recording data on the substrate of the first half-disc 31. Hole. Next, the sputtering process is to deposit the required film layer on the substrate. In the case of this invention 1221612 V. Description of the invention (6), the sputtering process is only on the first layer, such as base ore-reflection; on the substrate of the film on the substrate, the ore is destroyed. The ore-spattering process can be performed on the -half disc δ-recording layer,-on the dielectric layer and a reflective layer. -Layer In addition, in the present invention, "+9" is in the second embodiment of the second half of the disc. In a more general embodiment, the sputtering process can have a pre-engraved printed pattern on the side. The side can also be a back-reflecting layer. The soil is reversed, with a pre-engraved printing pattern followed by the 'fitting procedure will be Jiang Chu _. In order to form a digital audio and video stele ::: = second half disc fitting'-half Discs… fitting] and middle: The fitting process is to form a digital video light stele. The younger brother of the two pieces of the pot is bonded to the bonding surface, and the spin coating method and screen printing method are used: see the bonding method By using, for example, e. Glue method, an adhesive layer is then pressed to press the first surface and the second bonding surface, and then UV curing (UV cu, rir; 〇nding), layer.
