Data record：
Solves data record this problem, we, which first have to find, can mould specific " steric information storage body " structure
Method, what this structure can be with data is different and ever-changing.It is more and more as the development of 3D printing technique is with ripe
Material the solid of an arbitrary shape by way of 3D printing, can be ultimately formed.This is just us by data record
The convenient technique in an engineering is provided into " steric information carrier " structure.Certainly the invention is not limited in using 3D printing
Technology moulds " steric information carrier " structure, might have more excellent substitute technology in the future and occurs, 3D printing technique here
It can be understood as a kind of current best practices.
It is understood that data are finally all made up of 0 and 1, the essence of record data is exactly " imprinting " difference on medium
Feature, to represent 0 and 1.For example, the principle of magnetic disc storage is exactly that the state of magnetic in card is controlled with magnetic head, so will
Carry out can and restore 0 and 1 accordingly；CD is exactly to burn out different reflective spots in card with laser, further according to light
Reflection angle and the difference of time, to judge 0 or 1.Likewise, data are dissolved into by the present invention also with similar principle
In " steric information carrier " structure.
We illustrate the principle of data record of the present invention with Fig. 1-2, and left side is one group of 0-1 sequence, and right side is then logical
Cross a laminar structure of 3D printing technique manufacture.In order to make it easy to understand, data and structure have been simplified to one by one by we here
Corresponding relation, i.e., 0 is represented in structure with circular hole, and 1 is represented with square hole.
General principle
Most ancient rock has had the history of 4,400,000,000 years away from the present in the world, is inspired by this, we are expected if can
Data recorded in rock according to certain specific rule, then it can necessarily withstand examining for time and adverse circumstances
Test, after 1 years, still data can completely be extracted, so as to which that realizes that people preserve to data ultimate tells
Ask-permanent data preservation.To achieve it, the present invention needs solve two key problems, one is how to remember data
Record in steric information carrier, another is how on the premise of steric information carrier is not destroyed, and data are extracted.
On this basis, such as Fig. 3-4, the structure of individual layer is built up and is stacked by we, is formed this hair
Visible record " steric information carrier " structure of data message, 3D printing technique can ensure firmly glue between layers
It is combined, the holding for years as an entirety is stable.
It should be noted that above legend is only to demonstrate principle to be used.In actual product, it is contemplated that fault-tolerant, correction etc.
Various factors, initial data can be subjected to one or many conversion, so as to be formed with functional intermediate data, then be made
Cause " steric information carrier " structure., will also be according to the property of material during manufacture, selection traits are stable, easily distinguish
The feature recognized represents data, such as the material element that density is different or form is different.Such as above-mentioned circular, square.
When supporting more than two kinds of features, such as along with triangle, rhombus, and each shape also divide four kinds of different sizes, then appoint
A kind of what feature of specification can now represent multiple numerical digits, such as four kinds of shapes, as four kinds of sizes, 16 systems, Mei Gete
Sign represents four numerical digits.
Embodiment two, as viewed in figures 5-8, the method for persistence data of the present invention are that two with the difference of embodiment one
Kind identification material represents the material identification point of different identification information；(can also be the material identification point of four kinds of unlike materials).Institute
The material identification point for stating two kinds of unlike materials is nichrome, one kind in Au, Pt, Pd alloy, gold and silver palldium alloy, pure titanium, resin
Or any two kinds in any a variety of, ceramic, glass sand.More specifically glass sand and Au, Pt, Pd alloy.The Material Identification
Point is to be capable of the identification point that tomoscan is read；It is successively to sweep to read the multi-layer information storage using tomoscan that described information, which is read,
Deposit internal printed material positional information.(preferably described identification point layered configuration, between adjacent layer identification point between be separated with ceramics and be
The wall of matrix material)
The material identification point of described two unlike materials represents 0 and 1 respectively, and (or four kinds of shapes of different shapes are known
The material identification point of other point or four kinds of unlike materials represents 0 respectively, 1,2,3).
That is, such as Fig. 5-7, the above " steric information carrier " structure is by different material element or by same substance member
The new object that element is formed by different shape or density, wherein the locus residing for each unit material element is according to specific
Coding rule is formulated.When making such novel substance, first original digital information is changed into according to specific coding rule
The spatial positional information of the material element of unit numerical characteristic is represented, then new object is formed with the means of class such as 3D printing.Then
The new object formed is become as a kind of data medium, is restored when by the positional information for forming all kinds of material elements of the object
When, it can inversely restore original digital information according to used coding rule when manufacturing the object.
In a word, core demand of the invention is not specific coding rule (initial data-＞ intermediate data), nor in detail
Thin manufacturing standard (intermediate data-＞ " steric information carrier " structure), but data are specifically converted by certain, finally
Fashion into the thought of " steric information carrier " structure.As shown in figure 8, data deposit is to three-dimensional with 3D printer by data-printing
In information carrier structure.
As shown in figure 9, data extraction is that the data being stored in steric information carrier structure are read with lossless detection method
Take out, i.e., the order of data extraction and data record is on the contrary, data extraction is from completely " steric information carrier " by data
The process restored in structure.In order to achieve this it is needed non-destructive testing technology is used, for not destroying " solid letter
