Description of drawings
By the detailed description of preferred, non-limiting example that is used to modify the device at optical disk edge and modifies the method at optical disk edge of the present invention, other features and advantages of the present invention will be more obvious, with reference to the accompanying drawings, to describe non-limiting example of the present invention below, wherein:
Fig. 1 is the synoptic diagram of the glue structural sheet of double-deck BD Blu-ray Disc;
Fig. 2 is the view of device that is used to modify the disc edge according to an embodiment of the invention;
Fig. 3 modifies the view of the device at disc edge for being used to according to another implementation of the invention.
Embodiment
Below with reference to Fig. 1,2,3 the specific embodiment of the present invention is described.
With reference to figure 1, the glue structural sheet that it has shown double-deck BD Blu-ray Disc comprises four glue layer A2 altogether, A3, and A4, A5, wherein the A1 layer is a disc substrates.When making double-deck BD blue light disk, need on the thick disc substrates A1 of 1.1mm the following glue layer of spin coating according to this: the cover layer A4 that replication layer A3 that the spacer layer A2 that 23 μ m are thick, 2 μ m are thick and 73 μ m are thick; Because the gross thickness that these glue layers are added up is thicker, therefore after spin coating was intact, the disc edge will gather many glue, thereby stability that influence reads to coil and disc is attractive in appearance, so need be removed.
Shown among Fig. 2 according to embodiment of the present invention a kind of and be used to modify disc, the device at especially double-deck BD blue light disk edge, this device comprises: whirligig, be used to place disc on it and drive the disc rotation, this whirligig comprises pallet 2 and is positioned at the turning axle 1 at pallet center, described pallet 2 is used to carry disc, and described turning axle 1 is used to drive the disc rotation; Remove adhesive dispenser 4, should remove the glue layer 3 that adhesive dispenser is arranged to close CD edge, be used to remove this glue layer to modify the disc edge; Dedusting device of air 5, this dedusting device of air be positioned at glue layer 3 under, be used for removing and removing the glue process by removing the dirt gas that adhesive dispenser produces.Preferably, this dedusting device of air 5 comprises air extractor.
The described adhesive dispenser 4 that removes can be cutter, and it is arranged to be on the same surface level with disc, and near glue layer 3.Diameter at disc is under the situation of 120mm, and the close optimum seeking site ground of described cutter and glue layer is at 61mm place, the center of distance disc.
In Fig. 3, shown according to another selectable embodiment of the present invention, structure difference among itself and Fig. 1 is that the described mucilage binding that removes is changed to laser instrument 6, its be arranged on glue layer 3 directly over, be used for removing the glue layer at disc edge by the glue layer 3 at gasification disc edge.
The method and the process at concrete modification disc edge are described below.
An embodiment referring to Fig. 2, be coated with above-mentioned three layers of glue layer A2, A3, A4 and solidify with UV after, this disc is placed on the pallet 2 of Fig. 2, by auto-control software cutter 4 is moved to the close position of separation disc sheet edge glue layer 3 then, be positioned at preferred 61mm place, center (diameter at disc is under the situation of 120mm) apart from disc; Activated drive mechanism then drives the disc rotation by turning axle 1, opens the air extractor 5 under the glue layer 3 simultaneously; In the process of disc rotation, disc edge glue layer 3 is crossed out by cutter 4, and produced simultaneously dirt gas is taken out by air extractor 5.Like this, the thick hardcover layer A5 (as shown in Figure 1) of spin coating 2 μ m on disc again, because this glue layer thin thickness, it also is to ignore that the disc edge has glue to gather, this glue layer can also play the effect of protection disc simultaneously.
Under the situation of the embodiment of Fig. 3, be coated with above-mentioned three layers of glue layer A2, A3, A4 and solidify with UV after, this disc is placed on the pallet 2 of Fig. 3; Activated drive mechanism then drives the disc rotation by turning axle 1, open simultaneously under the glue layer 3 air extractor 5 with and directly over laser instrument 6; In the process of disc rotation, disc edge glue layer 3 is fallen by the laser gasification of laser instrument 6, and produced simultaneously dirt gas is taken out by air extractor 5.Like this, the thick hardcover layer A5 (as shown in Figure 1) of spin coating 2 μ m on disc again, because this glue layer thin thickness, it also is to ignore that the disc edge has glue to gather, this glue layer can also play the effect of protection disc simultaneously.
Although with reference to the accompanying drawings, the method that is used to modify the device at disc edge and modifies the disc edge of the present invention is illustrated, above-mentioned disclosure only is in order to understand the present invention better, rather than limits the scope of claim by any way.So all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, and are included in protection scope of the present invention.
