Abstract
The utility model relates to an improved DVD optical disk comprising two substrate layers which are mutually bound, a chamfer angle is formed on the periphery of at least one substrate layer which is near to one side of the bonding surface, the chamfer angle is N multiplied by 45 DEG, wherein the value of the N is 0.05mm-0.3mm, and the preferential value is 0.15mm. As certain space is formed on the periphery of the bonding surface due to the chamfer angle, no bubbles are produced when the two substrate layers are bonded, and the structure can not only ensure the production quality of the optical disk, but also lead the shape of the optical disk to be aesthetic.
Description
Technical field
The utility model relates to a kind of CD, is a kind of improved DVD CD specifically.
Background technology
Along with popularizing of multimedia technology, the DVD CD is because advantages such as its capacity is big, low price obtain application more and more widely.Existing DVD CD generally comprises mutually two bonding substrate layers and since the DVD CD in process of production its substrate layer periphery more or less have some burrs, therefore when bonding, can produce bubble when two substrate layers.If bubble is created in the block of information of CD, then can causes the defective or need degradation processing of CD quality, even cause CD to be scrapped; If bubble is created in the non-block of information of CD, then influence the attractive in appearance of CD profile.
The utility model content
At the deficiency of above-mentioned prior art, the utility model provides a kind of improved DVD CD that can avoid CD to produce bubble in process of production.
The utility model is achieved in that a kind of improved DVD CD, comprises two bonding substrate layers mutually, has opened chamfering at least one described substrate layer near the periphery of adhesive surface one side.
The utility model also has following attached technical characterictic:
Described chamfering is N * 45 °, and wherein the value of N is 0.05mm-0.3mm.
The value of described N is 0.15mm.
All opened described chamfering at described two substrate layers near adhesive surface one side periphery.
A kind of improved DVD CD that the utility model provides compared with prior art has following advantage: in the production run of CD, when two substrate layers are bonding, though it is jagged on the substrate perimeter, because the utility model has been opened chamfering at least one described substrate layer near the periphery of adhesive surface one side, therefore the periphery at adhesive surface has produced certain space, thereby make and can not produce bubble when two substrate layers are bonding, this structure not only can guarantee the quality of production of CD, and makes the CD profile very attractive in appearance.
Description of drawings
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Embodiment
Referring to Fig. 1, a kind of optimal way of a kind of improved compact disk structure of the utility model is shown, comprise two bonding substrate layers 1 mutually, opened chamfering 2 at least one described substrate layer 1 near the periphery of adhesive surface one side, described chamfering 2 is N * 45 °, wherein the value of N is 0.05mm-0.3mm, and preferred value is 0.15mm.Therefore, at the periphery of adhesive surface because chamfering has produced certain space, thereby make and can not produce bubble when two substrate layers are bonding that this structure not only can guarantee the quality of production of CD, and makes the CD profile very attractive in appearance.In implementation process, can all open chamfering near adhesive surface one side periphery at two substrate layers, also can only open chamfering near adhesive surface one side at a substrate layer, the number of degrees of chamfering are not limited to 45 °, can also select other the number of degrees for use, as 30 °, 60 ° etc.The big or small N of chamfering also can suitably select for use according to the thickness of substrate layer.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
