Abstract
The utility model relates to a data storage medium, particularly to an optical disk which has action of preventing interference of electromagnetic wave. The utility model comprises a transparent basal plate, a recording layer and a protecting layer, wherein the recording layer is glued on the transparent basal plate, and the recording layer comprises a reflecting layer, and a transparent layer is glued on the recording layer. An organic shielding material layer is arranged between the protecting layer and the transparent layer, and thickness of the organic shielding material layer is 0.07mm. The structure principally solves the technical problem that the existing optical disk doesn't have better shielding and protecting function to the electromagnetic wave so as to produce error codes easily when reading. Under the precondition that the utility model doesn't increase overly optical disk thickness, the utility model decreases error code rate of reading the optical disk.
Description
Technical field:
The utility model relates to a kind of data storage medium, particularly a kind of CD with anti electromagnetic wave interference effect.
Background technology:
CD is the same with disk to be a kind of data storage medium that generally uses at present; its integral thickness must remain on about 1.2mm; and the thickness of the transparency carrier of conventional optical disc is about 1.0mm; most thickness that accounted for is so can only realize with very thin hyaline layer data logging protection once.
China's utility model patent instructions (Granted publication number: CN2470914Y) disclose a kind of CD; see also Fig. 1: it comprises transparency carrier 1 ', recording layer 2 ', protective seam 5 '; wherein recording layer 2 ' is bonded on the transparency carrier 1 '; comprise a reflection horizon 3 ' in the recording layer 2 '; hyaline layer 4 ' is bonded on the recording layer 2 '; the thickness of described transparency carrier 1 ' is between 0.5-0.9mm, and the thickness of protective seam 5 ' is between 0.3-0.5mm.Utilize bigger thickness space protection optical disc data layer, make bonding non-data face protective seam can be effectively used to print commercial advertisement and utilize various means to reach false proof purpose simultaneously.
But, because the CD of said structure does not have shielding protection feature capability preferably to electromagnetic wave, and is to have gathered a plurality of light, electric installation in the computer host box, therefore, be necessary very much to improve the electromagnetic wave proof ability of CD, the bit error rate in the time of with the minimizing reading of data.
The utility model content:
The purpose of this utility model provides a kind of organic screen CD, mainly solve existing CD electromagnetic wave is not had shielding protection feature capability preferably, so that be easy to generate the technical matters of error code when reading, exceeding under the prerequisite that increases disk thickness, reduce the bit error rate that reads CD.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of organic screen CD; comprise transparency carrier, recording layer, protective seam; wherein; recording layer is bonded on the transparency carrier; comprise a reflection horizon in the recording layer; hyaline layer is bonded on the recording layer, it is characterized in that: be provided with an organic shielding material layer between protective seam and the hyaline layer, the thickness of this organic shielding material layer is 0.07mm.
The thickness of described transparency carrier is between 0.5-0.9mm, and the thickness of protective seam is between 0.3-0.5mm.
This organic shielding material layer reaches shielding strong electromagnetic wave ability in the 10MHz-3000MHz frequency range be more than 98%.
Advantage of the present utility model is as follows:
Be provided with an organic shielding material layer between protective seam of the present utility model and the hyaline layer; the thickness of this organic shielding material layer is 0.07mm; realize the electromagnetic to external world interference of CD under the prerequisite that increases disk thickness exceeding, reduced the bit error rate when reading.
Description of drawings:
Fig. 1 is the structural representation of existing CD.
Fig. 2 is the structural representation of the utility model organic screen CD.
Embodiment:
See also Fig. 2, it is the structural representation of a kind of organic screen CD of the utility model.As shown in the figure: it comprises transparency carrier 1, recording layer 2, protective seam 3; wherein; recording layer 2 is bonded on the transparency carrier 1; comprise a reflection horizon 3 in the recording layer 2; hyaline layer 4 is bonded on the recording layer 2; it is characterized in that be provided with an organic shielding material layer 6 between this protective seam 5 and the hyaline layer 4, the thickness of this organic shielding material layer 6 is 0.07mm.
The thickness of above-mentioned transparency carrier 1 is between 0.5-0.9mm, and the thickness of protective seam 5 is between 0.3-0.5mm.
This organic shielding material layer is mainly mixed by organic substrate, modification batching and conductive shield functional material and forms, and this base material is a macromolecular material, and this modification batching is an Organic Chemicals; When above-mentioned material adds up to 180 parts according to parts by weight, 100 parts of base materials, modification batching 25-55 part, conductive shield functional material 25-55 part.Through test, it reaches shielding strong electromagnetic wave ability in the 10MHz-3000MHz frequency range be more than 98%.
Claims (2)
