Description
Technical Field
The present invention relates to the field of optical storage devices, and more particularly, to a storage device for an optical disc.
Background
With the further development of the digitization industry, the utilization rate of data storage devices is gradually increased. Optical storage, which is capable of storing data safely, at low cost, for long periods of time, is becoming increasingly popular. Compared with the expensive price, complex maintenance and high environmental requirement of hard disk storage, the cost of using optical disk storage is lower, and the stored data is safer and more stable. Because the optical disk storage does not need to rotate continuously like a hard disk, the energy consumption is lower, and because the structure of the optical disk determines that the optical disk has longer service life than the hard disk, the optical disk can be used for 50 years or even longer, and does not need to be replaced frequently. With the development of error correction technology, the reliability of data stored in the optical disc is greatly improved. Because the data stored in the optical disc is recorded on the metal film of the disc by the purely physical metal ablation technology, the process is irreversible, so that the data cannot be tampered, and the stability of the data is ensured on the physical level. The hard disk and the magnetic tape become fragile if they are exposed to water or in a humid environment, and the optical disk is not affected by these influences, and data can be normally read even in an office environment at a temperature higher than 35 ℃.
Optical storage, which has such many advantages, is increasingly used in storage. Among the optical storage devices, there is a circular turntable type optical storage device, which has been gradually popularized in the field of optical storage due to its high storage density, small volume and low manual intervention. The existing optimization of the disk round rotating disk type disk box of the optical disk is mostly directed at the optical disk slot, and mainly solves the problem of how to stably store the optical disk in the optical disk slot, but never considers how to ensure the stability of the optical disk in motion in the process of the optical disk entering and exiting the optical disk slot. The round turntable type disc box of the optical disc always has the problem that the optical disc does not smoothly move and is not smooth, the groove bottom of an optical disc groove in the traditional disc box is mostly in a structure with the radian similar to that of the excircle of the optical disc, the smooth movement of the optical disc can be ensured by the structure, and under the action of no external force, the circular arc at the groove bottom of the optical disc groove can be tightly attached to the static state due to the inertia of dead weight so as to be positioned at the lowest part of the circular arc, but when the turntable rotates, the optical disc vertically jumps or shakes left and right, so that the probability of collision between the optical disc and. In addition, in order to slide the optical disc out of the optical disc drive smoothly, one end of the disc cartridge is necessarily opened, and when the base rotates, the optical disc is easily thrown out of the optical disc slot due to the action of centrifugal force. Once the disc collides or is thrown out of the disc slot, the disc is inevitably damaged in an untwisting way, resulting in data disaster and immeasurable loss.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the present invention provides a storage device for optical discs, which makes the movement of the optical discs more smooth and stable, and safer.
The utility model adopts the technical proposal that:
the storage device of the CD is in a ring shape and is provided with an inner side and an outer side, a plurality of vertical storage grooves of the CD are distributed along the radial direction of the storage device, the storage grooves point to the circle center of the storage device, the bottom of each storage groove is provided with a first horizontal plane and a second horizontal plane, the first horizontal plane is positioned on the inner side of the second horizontal plane, and the second horizontal plane is higher than the first horizontal plane.

Further, a third horizontal plane is arranged between the first horizontal plane and the second horizontal plane, step transition is adopted between the first horizontal plane and the third horizontal plane, and slope transition is adopted between the second horizontal plane and the third horizontal plane.
Only when the optical disk is continuously exerted with the pushing force, the optical disk can rise from the first horizontal plane to the third horizontal plane and then roll from the third horizontal plane to the second horizontal plane, and the step can enable the optical disk to be still in the storage device under the condition of insufficient pushing force, so that the influence of centrifugal force during circular motion of the storage device is overcome; the inclined plane is arranged between the third horizontal plane and the second horizontal plane, so that the movement process of the optical disk from the second horizontal plane to the first horizontal plane is accelerated, and the optical disk can fall to a storage position and reach a static state more quickly.
Further, the storage device comprises an inclined surface transition outer ring area from the second horizontal surface to the third horizontal surface and an arc-shaped storage inner ring area from the third horizontal surface to the inner side of the circular ring; the first horizontal plane is located at the lowest point of the arc-shaped storage inner ring area, the inner side of the arc-shaped storage inner ring area is provided with a buffer structure, and the cambered surface of the arc-shaped storage inner ring area connecting the buffer structure and the lowest point is matched with the outer contour of the optical disk.

Further, the storage device is provided with a slotted disc framework, the height difference between the slotted disc framework and the first horizontal plane is 8-12 mm, the height difference between the slotted disc framework and the second horizontal plane is 1-5 mm, and the height difference between the slotted disc framework and the third horizontal plane is 6-10 mm.
The groove disc framework is regulated to better adapt to the optical disc, the movement of the optical disc to and from the optical disc driver and the storage device is not blocked because of being too high, and the optical disc cannot be kept vertical because of being too low.
Furthermore, the storage device can be connected with a plurality of optical drives which are arranged in a fan shape, and the inlets of the optical drives point to the circle center.
