Abstract
The invention provides a novel ceramic digital optical disc (1) which is applied to constant storage of computer digital signals. The disc comprises a ceramic base layer (2), a fiber reinforced layer (3), a reflective layer (4), a high-temperature resistant laser photosensitizing dye, a pigment coating (5) and a low-temperature transparent glaze layer (6). The base layer (2) of the novel ceramic digital optical disc is made of kaolin; and both the reflective layer (4) and the low-temperature transparent glaze layer (6) of the novel ceramic digital optical disc are made of glazes. The overall disc is manufactured through sintering. The novel ceramic digital optical disc has the advantages of fire resistance, high-temperature resistance, corrosion resistance and the like, and the recorded digital signal of the disc is not influenced by magnetic field and current. In addition, the service life of the ceramic is very long, therefore, the ceramic digital optical disc is particularly suitable for constantly recording digital signals.
Description
Technical field
A kind of new digital pottery CD, it act as the recording medium of digital signal, for the persistence of digital signal.
technical background
Since nineteen seventies, along with the high speed development of computer technology, the mankind enter digital times.Digital times produces extremely far-reaching influence to human civilization, can predict, and in the near future, all cultural achievement of the mankind all will be come to be preserved in a digital manner.At present, along with the high speed development of computer technology, semiconductor technology and network technology, people have got used to a large amount of digital signals to be stored in the middle of jumbo hard disk, CD, semiconductor flash memory device and network hard disc.But above-mentioned data storage medium but also exists some fatal defects.
First, be no matter the flash memory body manufactured by hard disk, CD or semiconductor, its life-span is all limited.After the full phase in longevity expires, hard disk can dry up because of lubricant, and electronic unit is aging and cannot work; CD then can be aging and broken because of plastic basis material; Semiconductor flash memory device then can because of its periphery electronic unit, aging circuit and losing efficacy.
Secondly, be no matter the flash memory body of hard disk, CD or semiconductor manufacturing, all do not meet the safety requirements of persistence digital signal.Although hard disk very high capacity, itself be not water-fast, high-intensity magnetic field, heavy current, corrosion, and fire and high temperature also make it impaired, thus cause data thoroughly to be lost; CD too not water-fast, burn into is fiery and the impact of high temperature; There are these problems too in semiconductor flash memory device.
Three, in above-mentioned three kinds of digital signal storage mediums, except the price of CD is lower, other price of two kinds all costly, is unfavorable for the digital signal of persistence magnanimity.
Above-mentioned three shortcomings, determine the needs that existing digital signal recording medium cannot meet permanent record digital signal, and this transmission for human civilization are very disadvantageous.
summary of the invention
The present invention utilizes the high stability of pottery and permanance to manufacture new digital pottery CD, to realize the persistence of digital signal.
Pottery is as one of Chinese four inventions, and its stability and permanance all obtain inspection.No matter porcelain manufactured before thousands of year, be always by people are used, view and admire, be still imbedded in underground, be even submerged in seawater, can keep its original appearance.Have only and smashed by physics mode, the integrality of pottery could be destroyed.Utilize stupalith to make new digital pottery CD, just can ensure that new digital pottery CD has the life-span reaching thousands of years.
New digital pottery CD (1) involved in the present invention is disc structure, intermediate position perforate.The porcelain embryo that its Ceramics Ceramic basic unit (2) is sintered by porcelain earth water mixing, for ensureing Ceramics Ceramic basic unit (2) intensity of new digital pottery CD, prevent the Ceramics Ceramic basic unit (2) of new digital pottery CD broken, can lay in the Ceramics Ceramic basic unit (2) of new digital pottery CD by glass fibre, fibrous asbestos, carbon fiber or other inorganic matter fiber the fabric reinforcement (3) that weaves.The Ceramics Ceramic basic unit (2) of new digital pottery CD, after high temperature sintering is shaping, optionally can carry out polishing to its A, B two sides.
After Ceramics Ceramic basic unit (2) high temperature sintering of new digital pottery CD involved in the present invention is shaping, carries out " gold-decorated " process on its A, B two surface, namely coat the glaze containing metal object, and then sinter.Ceramics Ceramic basic unit (2) the AB face of the new digital pottery CD after sintering is all provided with metallic reflector (4).
The Ceramics Ceramic basic unit (2) of new digital pottery CD involved in the present invention, can in the resistant to elevated temperatures laser photosensitive dyestuff of the upper coating of metallic reflector (4), pigment coated (5) after completing metallic reflector (4) sintering.After treating after resistant to elevated temperatures laser photosensitive dyestuff, pigment coated (5) drying, laser photosensitive dyestuff, pigment coated (5) are coated with low-temperature transparent glaze (6) again.Finally, new digital pottery CD Ceramics Ceramic basic unit (2) being coated with low-temperature transparent glaze is put into low-temperature sintering stove and sinters, new digital pottery CD (1) can be obtained.
New digital pottery CD (1) involved in the present invention has following advantage.
1, good endurance: pottery is as a kind of inanimate matter product, and it is unlimited that its life-span can be described as.
2, good stability: pottery itself is not by magnetic, electricity, water, fire, high temperature and various acid, alkali and salt corrosion.Laser photosensitive dyestuff, pigment coated (5) are inherently resistant to elevated temperatures, therefore also can not because of fire, high temperature and affect data security.
And the low-temperature transparent glaze (6) be coated on outside new digital pottery CD can form tight glaze paint protective seam, thus protection is formed to metallic reflector (4) and laser photosensitive dyestuff, pigment coated (5).
3, crush resistance is strong: pottery itself is frangible, but by laying enhancement Layer (3) in the middle of the Ceramics Ceramic basic unit (2) of new digital pottery CD, the anti-crushing performance of new digital pottery CD can significantly improve.
4, cheap: kaolin resource enriches, cheap, thus the prices of raw and semifnished materials of new digital pottery CD (1) are extremely low.The manufacturing process of new digital pottery CD (1) is simple.Thus price is very cheap, is convenient to a large amount of buying.
5, can be connected with prior art: laser-optical disk technology is a ripe digital signal record technology, most PC has all been equipped with laser-optical disk read write line, only need purchase new digital pottery CD, the persistence of digital signal can be completed.
6 and come into operation along with the laser instrument that the glistening light of waves such as blue laser, violet laser is shorter; And the maturation of multilayer laser photosensitive coating technology.The memory space of CD there has also been very large raising.New digital pottery CD can meet the requirement of forever depositing all a large amount of digital signals.
7, new digital pottery CD is applicable to the entity and individual such as archives, library, government department, school and preserves various digital signal works.
The present invention has wide market outlook.
