Method.
Background technique
With the further development of digitlization industry, data storage device utilization rate is gradually increased.Can safely, it is low at
Originally, the optical storage of store data long term gradually has been favored by people.Relative to the expensive of hard-disc storage, maintenance it is complicated,
Environmental requirement is high, using the cost of optical disc storage is lower, storing data is safer, stablizes.Because being not required to using optical disc storage
It constantly to be rotated as hard disk, the energy consumption used is lower, and because the construction of CD itself also determines its service life
It is longer than hard disk, it can be used 50 years or even longer, do not need often to replace.With the development of error correction alignment technique, CD saves number
According to reliability greatly improve.Because the data of optical disc storage are the gold by the ablation of metals technical notes of pure physics in disc
Belong to film on, this process be it is irreversible, distort data can not, ensure that the stability of data from physical layer.Hard disk
If meeting water with tape or can become very fragile in a humid environment, CD is not influenced but by these, even if being higher than 35 DEG C
Working environment in can also be with normal read data.
The optical storage for possessing so many advantage, the application in terms of storage are further extensive.In many light storage devices,
There is a kind of light storage device type --- rotating disc type CD server, because its CD stores, density is high, own vol is small, manual intervention
It is low, it slowly popularizes and comes in the field of optical storage.Such as: Chinese Patent Application No. is that CN106710609A discloses wherein one
The CD server of kind rotating disc type type, scheme are that sensor sends instructions to driving device, control driving device driving turntable
Motion state, when sending movement instruction, turntable rotates a certain angle, and when sending still command, turntable stops operating, and enables and needs to make
CD is corresponding with manipulator, and manipulator crawl CD is facilitated to be sent into CD-ROM drive.Another example is: Chinese Patent Application No. is
CN108320759A discloses the CD server patent of another rotating disc type type, unlike the scheme of CN106710609A,
On the basis of CN106710609A scheme, it joined image acquisition device, position sensor and control chip, image acquisition device and use
Mark in acquisition CD disk, position sensor are used to acquire the location information of plate rail, and control chip receives two kinds of information
And command adapted thereto control driving device rotation turntable is issued, this scheme further improves the lookup accuracy rate of CD, and deposits
The built-in CD-ROM drive of storage device allows the safer convenience of the use process of CD it is not necessary that CD grabbing is gone out memory.Above-mentioned two
Although scheme all inherits the few advantage of the large capacity of traditional rotating disc type CD server, manual intervention, while also improving manipulator
The accuracy rate for searching CD, if but both not having it is considered that in order to possess larger capacity turntable is made bigger, originally
Groove design for stored CD not can guarantee CD and be always ensured that plumbness in access procedure.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of Wheel-type CD casket and disc accessing method, makes to be stored in light
CD in disk casket is always ensured that plumbness in access procedure.
The technical solution adopted by the present invention is that:
A kind of Wheel-type CD casket, the CD casket is annular in shape, has an inside and an outside, radially divides along CD casket
It is furnished with the vertical holding tank of multiple CDs, holding tank is directed toward the center of circle of CD casket, and the center of circle of CD casket is arranged in driving means, special
Sign is that the CD casket includes slotted disk bracket, upper slotted disk and lower slotted disk, and the upper slotted disk and lower slotted disk are connected by slotted disk bracket
It connects, the holding tank of upper slotted disk is corresponding with the holding tank of lower slotted disk.
The holding tank of slotted disk limits edge on CD on CD casket, and the holding tank of slotted disk limits CD lower edge under CD casket, on
The holding tank of lower slotted disk is corresponding, acts on same CD, CD is made to remain plumbness in access procedure.It will not be because of
The variation of CD casket own vol causes CD run-off the straight during access, avoids manipulator and grasp to CD
Accident occurs when making, ensure that the smoothness of access procedure movement.The Wheel-type CD casket of the prior art only has lower tray, in order to
CD can smoothly pass in and out CD casket, and not wear CD, and the storage groove width in lower tray is larger than disk thickness, this
Sample results in what CD can not be completely erected to be stored on CD casket.And in order to avoid the abrasion to cd side, holding tank
Depth be it is more more shallow better, which results in the angle change of CD is very big.Come especially for the CD casket of large capacity
It says, inertia caused by wheel disc rotation is very big, leads to CD periodic wobble on CD casket, generates in this way to holding tank side
Biggish compressing, makes its rapid fatigue aging, and service life substantially reduces, in some instances it may even be possible to generate mechanical system risk.In addition,
The disc tilt angle change of only lower tray is too big, also increases that CD enters the alignment difficulty of CD-ROM drive and CD is touched with CD-ROM drive
Hit possibility.Although this patent simply increases a upper slotted disk structure, CD is limited by upper and lower holding tank, tilt angle
It is limited in the angle of very little, this structure is more advantageous to alignment when CD disengaging CD-ROM drive, and can be avoided CD casket and turn
Periodic wobble caused by CD when dynamic, thus the depth of holding tank can be made more shallow instead up and down, reduce to CD
A possibility that abrasion of data field.The Wheel-type CD casket of this particularly suitable large capacity of structure, for existing storage data quantity
Increasing demand, the quantity on CD casket is more and more, existing CD casket design, structural behaviour, stability and

Dry sector slotted disk respectively manufactures, and the circular slotted disk an of entirety multiple fan-shaped slotted disks is spliced back again after the completion of manufacture.In this way
Original technique limitation is not only breached, also simplifies process, reduces manufacturing cost.Lower slotted disk in the prior art is all made of
Integrally formed structure, in the case where memory capacity is little, this structure is simple, easy to process, finished product good integrity.But such as
Fruit continues the lower slotted disk that large capacity is processed by the way of integrally formed, then can bring a series of problems.Size constantly adds
Greatly, the size of existing huge capacity compact discs casket is at least 1.5 times of conventional capacity or more, and has the tendency that incrementally increasing.In this way
Big annulus area carries out integrally formed, and not only die cost is expensive, and the requirement to material and technique is also than traditional technology
Several grades on height, moreover precision controlling difficulty wants at least one high magnitude, i.e., to guarantee that overall leveling prevents from making again
Warpage etc. will not be deformed in, and once has the damage of some details, need integral replacing, this is not only at high cost, and to storage
Information Security brings high risk.A series of problems brought by after increasing in view of size, and with the increasing of size
These problems are added more to highlight, in order to meet the needs of following big data storage, this patent is from structure, using fan-shaped slotted disk
Large scale is decomposed into unit small size by the structure spliced, although increasing the processes such as splicing debugging, structural behaviour,
Stability and security performance are all much higher than integrally formed structure.In big data storage, more advantage is when a certain portion
When bit loss badly needs replacing, maintenance work only influences to be stored in a small amount of CD on the sector element, substantially increases data
Safety.
Further, the CD casket further includes driving gear, adjustment gear and driven gear, and driving gear is CD casket
Rotational power is provided, driven gear is connect with slotted disk bracket, and adjustment gear is engaged with the active gear teeth, driven gear respectively；It is described
