Description

Technical Field

[0001] The present invention relates to the field of information storage technology, in particular to a dynamically adjustable holographic optical storage medium and a preparation method thereof. Background Art

[0002] Holographic optical storage devices are complex systems that integrate optical interferometry, precision mechanical control, and optoelectronic signal processing. Their core function is to record and reproduce holograms through the interaction of coherent light modulation and the medium. From laboratory research to commercial exploration, these devices are developing towards high precision, miniaturization, and intelligence, providing key technological support for future massive data storage. Holographic optical storage, a key core element of optical storage media, primarily utilizes the interaction between light and materials to achieve storage.

[0003] Optical storage media are generally used in conjunction with an operating system when in use, and therefore need to be installed in a fixed position, including a chassis. However, some existing chassis or other objects that fix optical storage media are placed in a standing, tilted or inclined state when in use. This causes the holographic optical storage medium to be not placed flat when in use, resulting in a reduced service life of the holographic optical storage medium. In addition, when the entire chassis is moved during use, vibration is inevitable, and vibrations of varying sizes will be transmitted to the optical storage medium, causing damage to the storage medium, which is not conducive to actual use.

When necessary, the outer ring 1 and the inner ring 2 can be prohibited from rotating.

[0021] See also Figures 1-4As shown, the fixing mechanism includes a mounting plate 14, which is fixedly connected to the top of the shell 4 near the middle, and an internal threaded ring 15 is fixedly connected to the top of the mounting plate 14. The bottom end of the internal threaded ring 15 passes through the mounting plate 14, and the internal thread of the internal threaded ring 15 is connected to a lifting screw 16. The top of the lifting screw 16 is fixedly connected to a knob 17, and the bottom end of the lifting screw 16 is rotatably connected to a fixing plate 18.

The top of the limit rod 19 passes through the mounting plate 14 and is movably connected to the mounting plate 14. The top of the fixing plate 18 is fixedly connected to evenly distributed heat dissipation fins 20.

[0022] During operation, the lifting screw 16 is rotated forward by the knob 17, driving the fixing plate 18 and the limit rod 19 to descend, so that the fixing plate 18 contacts the top of the storage medium body 13, thereby fixing the storage medium body 13, wherein the heat dissipation fins 20 can play a role in auxiliary heat dissipation.

[0023] See also Figure 2-Figure 4 As shown, the shock filtering mechanism includes a rubber connecting ring 5, and a rubber connecting ring 5 is fixedly connected to the outer wall of the placement shell 4 and the inner wall of the water storage shell 3 near the top. The cross-section of the rubber connecting ring 5 is arranged in an arc shape, and a water opening 6 is opened near the middle of the bottom of the water storage shell 3. A rubber bellows 7 is fixedly connected to the bottom of the placement shell 4 near the middle, and the rubber bellows 7 is connected to the inside of the water opening 6. A circular plate 8 is fixedly connected to the bottom of the rubber bellows 7, and a U-shaped plate 9 is sleeved on the outside of the rubber bellows 7.

[0024] During operation, when vibration or shaking occurs, the vibration will be transmitted to the storage medium body 13 through the ear plate 30 and the support rod 22, but when the vibration is transmitted to the storage medium body 13, it will pass through the coolant between the water storage shell 3 and the placement shell 4. The coolant can fully filter the vibration, thereby reducing the vibration of the storage medium body 13. If the vibration amplitude is large, the placement shell 4 will float up and down, causing the coolant in the water storage shell 3 to move up and down and push the rubber bellows 7 and the shock-filtering spring 10 to reciprocate up and down through the water opening 6. The floating of the rubber bellows 7 and the shock-filtering spring 10 can achieve a good buffering effect.

[0025] See also Figure 7As shown, the dynamic fixing assembly includes an integral rotating mechanism, a first rotating mechanism and a second rotating mechanism.

Uniformly distributed positioning openings 23 are opened at the end of the fixed tube 21 opposite to the flange tube 24. The end of the positioning block 25 opposite to the fixed tube 21 extends into the positioning opening 23. The end of the support rod 22 away from the flange tube 24 is rotatably connected to the fixed tube 21. The movable ring 29 and the end of the support rod 22 are sleeved with a positioning spring 28, and the two ends of the positioning spring 28 are fixedly connected to the flange tube 24 and the movable ring 29 respectively. Movable grooves 26 are provided on both sides of the end of the flange tube 24 opposite to the fixed tube 21. Cylindrical blocks 27 are provided in the two movable grooves 26.

Slide grooves are respectively provided at the top and bottom of the inner side of the rectangular opening 32, and the top and bottom of the movable block 33 are fixedly connected with sliders matching the slide grooves.

[0026] During operation, first pull the flange tube 24 and then move the positioning block 25 away from the positioning opening 23 to compress the positioning spring 28. When the positioning block 25 disengages from the positioning opening 23, the cylindrical block 27 will also disengage from the movable groove 26. At this time, the flange tube 24 can be rotated so that the end of the flange tube 24 rests against the cylindrical block 27. In this way, the flange tube 24 will not be pushed back to the initial position by the rebound force of the positioning spring 28, so that the outer ring 1 and the fixed tube 21 can rotate on the support rod 22.

[0027] See also Figure 5-Figure 9 As shown, the first rotating mechanism includes a longitudinal rod 40, and the outer side of the inner ring 2 is symmetrically fixedly connected with the longitudinal rod 40. The ends of the two longitudinal rods 40 that are away from each other respectively pass through the outer ring 1 and are movably connected to the outer ring 1. The ends of the longitudinal rods 40 that are away from the inner ring 2 are fixedly connected with a gear 41. A rectangular opening 32 is symmetrically opened on the outer side of the outer ring 1 near the gear 41. A movable block 33 is slidably connected to the inner wall of the rectangular opening 32. The side of the movable block 33 that is away from the inner ring 2 extends to the outside of the rectangular opening 32. The end face of the movable block 33 opposite to the gear 41 is fixed. A tooth block 34 is connected, which meshes with the gear 41. A movable spring 35 is fixedly connected between the end surface of the movable block 33 away from the gear 41 and the inner wall of the rectangular opening 32.

[0028] During operation, the movable block 33 is pulled to compress the movable spring 35, so that the tooth block 34 is disengaged from the placement shell 4, and then the screw 38 is tightened so that the screw 38 can press the movable plate 36, so that the movable block 33 will not be pushed to the initial position by the rebound force of the movable spring 35.

[0029] See also Figure 3 and Figure 4 As shown, the second rotating mechanism includes a transverse supporting screw rod 42, and a transverse supporting screw rod 42 is provided on the outer side of the inner ring 2 near the center of both ends. The ends of the transverse supporting screw rod 42 opposite to the inner ring 2 respectively penetrate the inner ring 2 and are rotatably connected to the inner ring 2. The opposite ends of the two transverse supporting screw rods 42 are respectively fixedly connected to the outer wall of the water storage shell 3, and the ends of the transverse supporting screw rods 42 are threadedly connected with internal thread flanges 43 near the inner ring 2.

[0030] During operation, the storage medium body 13 can be used normally after the inner thread flange 43 is rotated away from the inner side of the inner ring 2 .

[0031] The method for using a dynamically adjustable holographic optical storage medium is mainly applicable to the dynamically adjustable holographic optical storage medium of claims 1-9, and the method mainly comprises the following steps: S1: Before use, first remove the two screw plugs 12, and inject an appropriate amount of coolant into the space between the water storage shell 3 and the placement shell 4 through the external water injection pipe 11. After filling, install the screw plug 12 on the external water injection pipe 11 to prevent coolant leakage; S2: The lifting screw 16 is rotated by the knob 17 so that the fixing plate 18 descends and contacts the top of the storage medium body 13, thereby fixing the storage medium body 13; S3: The ear plate 30 needs to be fixed at a specified position by bolts 31 or other fixings. The support rod 22 can be fixed horizontally or vertically. The fixing angle can be adjusted according to actual needs. S4: When the positioning block 25 is disengaged from the positioning opening 23, the cylindrical block 27 will also be disengaged from the movable groove 26. At this time, the flange tube 24 can be rotated so that the end of the flange tube 24 abuts against the cylindrical block 27. In this way, the flange tube 24 will not be pushed back to the initial position by the rebound force of the positioning spring 28, so that the outer ring 1 and the fixed tube 21 can rotate on the support rod 22. S5: disengage the tooth block 34 from the placement shell 4, and then tighten the screw 38 so that the screw 38 can press the movable plate 36, so that the movable block 33 will not be pushed to the initial position by the rebound force of the movable spring 35.

[0032] To sum up, the problem that the holographic optical storage medium is not placed flat, which will reduce the service life of the holographic optical storage medium, and when the entire chassis is moved during use, large or small vibrations will be transmitted to the optical storage medium, causing damage to the storage medium, which is not conducive to actual use is effectively solved.

[0033] Working principle: When using this technical solution, first remove the two screw plugs 12 by rotating them, and inject an appropriate amount of coolant into the space between the water storage shell 3 and the placement shell 4 through the external water injection pipe 11. After filling, install the screw plug 12 on the external water injection pipe 11 to prevent coolant leakage. When the space between the water storage shell 3 and the placement shell 4 is filled with water, the placement shell 4 will float up. Next, place the storage medium body 13 at the center of the placement shell 4, and turn the lifting screw rod 16 forward by turning the knob 17 to drive the fixing plate 18 and the limit rod 19 to descend, so that the fixing plate 18 contacts the top of the storage medium body 13, thereby fixing the storage medium body 13, wherein the heat dissipation fins 20 can play a role in auxiliary heat dissipation.

[0034] Next, the ear plate 30 and the water storage shell 3 are installed as a whole in the specified position in the chassis through the ear plate 30 and the bolt 31 or other fixing parts. The support rod 22 can be installed vertically or at other angles. After the installation is completed, the storage medium body 13 can be kept in a horizontal state according to actual needs. If the storage medium body 13 needs to be kept in a horizontal state, first pull the flange tube 24 and move the positioning block 25 away from the positioning opening 23 to compress the positioning spring 28. When the positioning block 25 is out of the positioning opening 23, the cylindrical block 27 will also be out of the movable groove 26. At this time, the method can be rotated. The flange tube 24 is formed by the outer ring 1 and the fixed tube 21. The outer ring 1 and the fixed tube 21 can rotate on the support rod 22, and then the movable block 33 is pulled to compress the movable spring 35, so that the tooth block 34 is disengaged from the placement shell 4, and then the screw 38 is tightened. The screw 38 can press the movable plate 36, so that the movable block 33 will not be pushed to the initial position by the rebound force of the movable spring 35. Finally, by rotating the inner thread flange 43 away from the inner side of the inner ring 2, the storage medium body 13 can be used normally.

[0035] When vibration or shaking occurs, the vibration will be transmitted to the storage medium body 13 through the ear plate 30 and the support rod 22, but when the vibration is transmitted to the storage medium body 13, it will pass through the coolant between the water storage shell 3 and the placement shell 4. The coolant can fully filter the vibration, thereby reducing the vibration of the storage medium body 13. If the vibration amplitude is large, the placement shell 4 will float up and down, causing the coolant in the water storage shell 3 to move up and down and push the rubber bellows 7 and the shock-filtering spring 10 to move up and down through the water opening 6. The floating of the rubber bellows 7 and the shock-filtering spring 10 can achieve a good buffering effect.

[0036] When the state of the chassis changes, the storage medium body 13 can still be rotated to a horizontal state. Because there is also coolant in the rubber bellows 7 at the bottom of the placement shell 4, the center of gravity of the placement shell 4 is at the bottom. Therefore, when the chassis tilts forward or backward, the outer ring 1 and the placement shell 4 can rotate as a whole. When the chassis tilts to the left or right, the longitudinal rod 40 on the inner ring 2 will rotate, so that the placement shell 4 and the storage medium body 13 are always kept in a horizontal state for use, and the coolant in the water storage shell 3 can cool the placement shell 4 and the storage medium body 13 through the properties of physical heat conduction, which can effectively improve the service life of the storage medium body 13.

[0037] When it is necessary to fix the outer ring 1, the inner ring 2 and the water storage shell 3 so that they do not rotate, their positions can be fixed. First, rotate the flange tube 24 so that the cylindrical block 27 enters the movable groove 26. The rebound force of the synchronous positioning spring 28 pushes the flange tube 24 to slide, so that the positioning block 25 enters the positioning opening 23, so that the outer ring 1 cannot rotate. Next, loosen the screw 38, and the rebound force of the synchronous movable spring 35 pushes the tooth block 34 to engage with the gear 41, so that the inner ring 2 as a whole will not rotate again. Finally, rotate the inner thread flange 43 so that the inner thread flange 43 presses against the inner wall of the inner ring 2, and fixes the water storage shell 3 and the placement shell 4 as a whole by friction so that they will not rotate again. The above operations can fix the position of the storage medium body 13.
