For example, the theoretical service life of the data storage medium 100 using the quartz substrate 1 with purity of more than 90% can reach more than thousand years; for another example, the theoretical service life of the data storage medium 100 using the quartz substrate 1 with a purity of 99% or more can reach 1 hundred million years or more; however, in practical applications, the higher the purity, the more expensive the quartz, and in view of economic and performance considerations, it is generally most appropriate to use 99.9% to 99.99% high purity quartz. In one embodiment, the quartz substrate 1 has a disk shape with a concentric circular hole in the center, as shown in fig. 2. It is to be understood that the shape of the quartz substrate 1 may be a square, a rectangle, a circle, or a modification thereof, and is not limited to the above embodiment.

In other embodiments, all the positions of each longitudinal data line 10 shown in the first embodiment may be set at unequal intervals, and may be set according to actual needs; similarly, all the positions of each horizontal data line 10 shown in the first embodiment may be arranged at unequal intervals, so that at least the data lines 10 to be collected are arranged at equal intervals during the reading and writing operation. In other embodiments, the staggered pitches in the radial direction of the adjacent data lines 10 shown in the second embodiment may not be equal, and the embodiment is not limited to this.
The first data source site 3, which is a groove opened on the quartz substrate 1, corresponds to the basic data 1. As shown in fig. 1 or fig. 2, the groove is a cylinder, and the cross section on the surface of the quartz substrate 1 is circular and is opened perpendicular to the thickness direction of the quartz substrate 1. In a specific embodiment, the cross-sectional diameter of the grooves is 220-245 μm, the depth H of the grooves is 15-25 μm, and the minimum distance D between the adjacent edges of the grooves in each data row 10 is 90-110 μm. For example, fig. 1 shows the grooves as cylindrical with a cross-sectional diameter of 220 μm and a depth H of 20 μm, the grooves being arranged next to each other in one of the data rows 10 without second data source sites 5 in between, with a minimum spacing H of 100 μm adjacent the edges. The grooves shown in fig. 2 are cone-like columns with a cross-sectional diameter at their top end of 245 μm, a diameter at their bottom end of 230 μm, and a depth H of 20 μm, and the grooves in one circle of the data rows 10 are arranged next to each other without the second data source sites 5 in between, and have a minimum arc length spacing at their top ends adjacent to the edges of 100 μm.

In actual production, most information sites are left after grooves are formed, and due to the fact that the information sites and the first data source sites 3 are in a relative concave-convex shape, different basic signals are fed back due to the fact that the reflection angles and the reflection times are different under the irradiation of a light source. It is understood that the second data source site 5 may also be an etched recess, and only needs to be able to significantly differ from the first data source site 3 to feed back a data signal, and in other embodiments, the second data source site 5 may also be a composite layer deposited or coated with other materials, such as magnetic materials, on the quartz substrate 1.
The following describes the preparation process of the data storage medium 100 of the present invention in detail with reference to fig. 3.
The method comprises the following specific steps:

step 2: f produced by ionizing carbon tetrafluoride gas-And etching the quartz substrate 1 by using plasma to obtain the first data source sites 3 preset on a plurality of data lines 10, thereby forming the data storage medium 100.
Wherein:
the etching speed is 150-200 nm/s. To achieve such an etch rate, a small amount of oxygen gas is typically added to the carbon tetrafluoride gas. This is because the etching rate of pure carbon tetrafluoride plasma gas for etching silicon dioxide is relatively slow, and after a small amount of oxygen is added, oxygen reacts with carbon tetrafluoride to release fluorine atoms, consuming part of carbon, so that the fluorine-to-carbon ratio in the plasma is increased, and thus the etching rate is greatly increased along with the increase of the density of fluorine atoms in the plasma. The volume ratio of the two is preferably (3-1): 1, especially 1: 1.
The carbon tetrafluoride gas is ionized through the space between the positive electrode and the negative electrode of the radio frequency power supply under the micro-positive pressure environment of 20-100pa, and the diameter of the electrode nozzle formed by the positive electrode and the negative electrode is smaller than that of the cross section of the groove. In one embodiment, when the diameter of the cross section of the groove is 220 μm, the diameter of the electrode tip can be 170 and 190 μm. More specifically, when the diameter of the cross section of the groove is 220 μm, the diameter of the electrode nozzle is 180 μm, the working distance between the electrode nozzle and the surface of the quartz substrate 1 is 2 μm, and a groove with a cross section diameter of about 220 μm and a depth of 20 μm can be etched by etching for about 30s, however, in the actual operation process, the etching time is related to the working distance between the electrode nozzle and the surface of the quartz substrate 1, and the closer the distance, the shorter the etching time required by the same structure is, the faster the molding is; conversely, the longer the distance, the longer the etching time required for the same structure, and the slower the formation.
The utility model discloses the application method of above-mentioned data storage medium 100 is further provided:
reading a data segment formed by the first data source position 3 and/or the second data source position 5 line by line according to a preset distance through a vision sensor, wherein the first data source position 3 and the second data source position 5 are respectively marked as 1 and 0, check bits are arranged at preset number of positions at intervals in the data segment, and the correctness of the data is verified by comparing the data identified by the check bits with the consistency of a set value.
Wherein the content of the first and second substances,
in one embodiment, the predetermined distance read by the vision sensor is the center distance of the adjacent sites, for example, if the sites arranged in the linear array have a diameter of 220 μm and the adjacent edges are spaced apart by 100 μm, the predetermined distance read by the vision sensor is 320 μm.
In one embodiment, check bits are set every 16 bit points in the data segment to verify the correctness of the data.
To sum up, the utility model discloses a data storage medium 100 adopts quartz material to be the substrate, has better resistance to wears the characteristic, and long service life reaches millennium or more than hundred million years theoretically. The quartz lining body is etched by adopting fluorine plasma generated by carbon tetrafluoride gas, so that the etching rate is high and the forming rate is high; and the correctness of the data is ensured through the setting of the check bit.
The above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and are not limited, and although the embodiments of the present invention have been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions to the technical solutions of the embodiments of the present invention may be made without departing from the spirit and scope of the technical solutions of the embodiments of the present invention.
