Abstract
The utility model discloses a kind of antistatic resistance to compression laser disc, including substrate, and the groove being arranged on substrate；And it is arranged at recording layer, reflecting layer, protective layer and printing layer on substrate；The substrate includes the first substrate layer, the second substrate layer and the 3rd substrate layer；The printing layer is arranged on the first substrate layer；The first substrate layer another side is fixed by glue-line and protective layer；The protective layer is bonded with reflecting layer；The recording layer includes upper recording layer and lower recording layer；The second substrate layer is provided between the upper recording layer and lower recording layer；Second substrate layer is translucent；Antistatic resistance to compression laser disc of the present utility model, using asymmetric irregular structure, electrostatic field can be destroyed, additionally by pasting antistatic PE films, electrostatic can be prevented well, meanwhile, substrate is arranged to three-decker, second substrate layer can either increase structural rigidity and crushing resistance, while can separate two recording layers.
Description
Technical field
It the utility model is related to a kind of laser disc, and in particular to a kind of antistatic resistance to compression laser disc, belong to disc technology field.
Background technology
CD is the equipment read and write using Principles of Laser, is a kind of additional storage developed rapidly, can deposit
The Multimedia digital informations such as various words, sound, figure, image and animation, existing disc types are various, but its agent structure
It is basically identical；Such as Chinese Patent Application No.：Had three layers 201580010964.7 the CD for disclosing an embodiment at least possesses
Recording layer, the recording layer is in information track record information；Recording layer possesses and had：Inner circumferential side region positioned at inner circumferential side；It is relatively interior
All side regions are located at outer circumferential side and record the data area of content information；And relative data region is located at the outer circumferential side of outer circumferential side
Region；Content information is recorded in the data area of more than 3 layers of recording layer, and by the upper strata in being regenerated towards inner circumferential
Appearance information regeneration switches to the point on upper strata of its next layer of content information and the point of lower floor is set at the most interior of data area
On the outside of all positions；For another example Chinese Patent Application No.：200810008316.X a kind of CD is disclosed, including data field and non-number
According to area, at least two symmetrical through holes are provided with the non-data area；CD provided by the invention passes through in non-number
According to through hole is set in symmetric position in area, pass through gas flowing during optical disk rotary, reduce the electrostatic field caused by frictional heat
Influence to digital independent；But after symmetrical through hole rotation, regular annular is formed, it can not destroy electrostatic well,
Its crushing resistance of other above-mentioned technical proposal is not good enough.
Utility model content
To solve the above problems, the utility model proposes a kind of antistatic resistance to compression laser disc, electrostatic field and increasing can be destroyed
Add crushing resistance.
Antistatic resistance to compression laser disc of the present utility model, including substrate, and the groove being arranged on substrate；And it is arranged at substrate
On recording layer, reflecting layer, protective layer and printing layer；The substrate includes the first substrate layer, the second substrate layer and the 3rd substrate
Layer；The printing layer is arranged on the first substrate layer；The first substrate layer another side is fixed by glue-line and protective layer；It is described
Protective layer is bonded with reflecting layer；The recording layer includes upper recording layer and lower recording layer；The upper recording layer and lower recording layer it
Between be provided with the second substrate layer；Second substrate layer is translucent；The lower recording layer and upper recording layer another side difference
It is bonded with reflecting layer and the 3rd substrate layer；Multiple irregular electrostatic fields are provided with the groove and destroy groove.
As preferred embodiment, antistatic PE films are fitted with outside the 3rd substrate layer.
Further, antistatic PE films are fitted with outside first substrate layer.
As preferred embodiment, first substrate layer and the 3rd substrate layer are made up of makrolon.
As preferred embodiment, second substrate layer is made up of translucent hardening plate.
The utility model compared with prior art, antistatic resistance to compression laser disc of the present utility model, is not advised using asymmetric
Then structure, electrostatic field can be destroyed, additionally by antistatic PE films are pasted, electrostatic can be prevented well, meanwhile, substrate is set
Three-decker is set to, the second substrate layer can either increase structural rigidity and crushing resistance, while can separate two recording layers.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
Embodiment 1：
As shown in figure 1, antistatic resistance to compression laser disc of the present utility model, including substrate 1, and the groove being arranged on substrate 1
2；And it is arranged at recording layer 3, reflecting layer 4, protective layer 5 and printing layer 6 on substrate；The substrate 1 include the first substrate layer 7,
Second substrate layer 8 and the 3rd substrate layer 9；The printing layer 6 is arranged on the first substrate layer 7；The another side of first substrate layer 7
Fixed by glue-line 10 and protective layer 5；The protective layer 5 is bonded with reflecting layer 4；The recording layer 3 includes the upper He of recording layer 11
Lower recording layer 12；The second substrate layer 8 is provided between the upper recording layer 11 and lower recording layer 12；Second substrate layer 8 is
It is translucent；Lower recording layer 12 and upper recording layer 11 another side is bonded with the substrate layer 9 of reflecting layer 4 and the 3rd respectively；It is described
Multiple irregular electrostatic fields are provided with groove 2 and destroy groove 13.
Antistatic PE films 14 are fitted with outside 3rd substrate layer 9.
Antistatic PE films 14 are fitted with outside first substrate layer 7.
The substrate layer 9 of first substrate layer 7 and the 3rd is made up of makrolon.
Second substrate layer 8 is made up of translucent hardening plate.
Antistatic resistance to compression laser disc of the present utility model, using asymmetric irregular structure, electrostatic field can be destroyed, is led in addition
Cross and paste antistatic PE films, electrostatic can be prevented well, meanwhile, substrate is arranged to three-decker, the second substrate layer can
Enough increase structural rigidity and crushing resistance, while two recording layers can be separated.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
