Description
Technical field
The CD array library structure, the memory device that belongs in the magnanimity field of optical storage technology is made the field.
Background technology
The typical structure of at present popular multiple driver CD server is made up of a mechanical arm, a plurality of driver and one or more CD rack, optic disc storage is on CD rack, finish the exchange of CD between driver and CD rack by the motion of mechanical arm, each driver all is an independently read/write server.The characteristics of this CD server are system service is subject to a driver in the transfer rate of a request transfer rates, the file size of storage is subject to the amount of capacity of a CD, thereby can not satisfy the actual demand of the application system (as multimedia application) of the big file of storage, high speed transmission data.
For this reason, people propose to utilize RAID (the Redundant Arrays of Inexpensive Disk) technology in the Disk Array to solve the problems referred to above that CD server exists.The core of RAID technology is to divide the parallel read/write that (data striping) technology realizes a plurality of media by data, thereby improves the whole I/O performance of memory device; Utilize data redundancy (data redundancy) technology to increase the reliability of memory device simultaneously.Yet, in optical disc memory apparatus, use above-mentioned RAID technology and but face very big difficulty.Chief reason is, storage medium and drive unit are to concern one to one in disk unit, and CD is typical mobile memory medium, driver number in CD server equipment is less than cd number far away, optic disc storage is on CD rack, and the read/write of data needs at first to finish CD by mechanical arm and just can carry out after the exchange between driver and the CD rack.And the typical structure of at present popular multiple driver CD server as shown in Figure 1, and one of its key character is exactly to have only a mechanical arm, and equipment is finished the exchange of CD between driver and CD rack by the motion of mechanical arm.Under a kind of like this structure, realize the RAID technology, owing to can not realize the synchronous load/unload of CD, CD can only sequentially be loaded on each driver, or order unloads from each driver, thereby very big time delay is arranged, make the competition of mechanical arm become the maximum bottleneck that influences the CD array equipment performance.If the mechanical arm of increase activity on the architecture basics of this CD server is alleviated competition, then the mechanical realization of CD server and control all become extremely complicated, have increased the complexity and the cost of equipment greatly.
For this reason, the scheme that realizes RAID technology (the RAIL-Redundant Arrays of Inexpensive Library technology of saying so accurately) between a plurality of CD server is mainly adopted in the realization of CD array equipment at present, and the core of this scheme is by increasing the purpose that the CD server number reaches increases the mechanical arm number.This method invents a high speed CD-ROM drive, huge capacity compact discs, a quick mechanical arm respectively, thereby has reached very high performance being present in the corresponding CD-ROM drive of a plurality of CD server, corresponding CD, corresponding mechanical arm.The shortcoming of this scheme is the support that needs a plurality of CD server, and its cost is high more a lot of than realize the RAID technology in single CD server.
Summary of the invention
For simple at device structure, under the lower-cost condition, realize the synchronous load/unload of CD, solve the race problem of mechanical arm in the CD server, the invention discloses a kind of CD array library structure, comprise CD rack, driver and mechanical arm, it is characterized in that: this structure comprises the CD rack that is driven by the CD rack drive unit, evenly distributed CD folder on described CD rack is to be positioned over CD in the CD folder and N to mechanical arm and driver one to one perpendicular to the CD rack direction; Described N is distributed in the next door of described CD rack to mechanical arm and driver, and described mechanical arm is between the driver and CD rack corresponding with it.
Above-mentioned CD rack drive unit can be the meshed transmission gear device.
The present invention proposes a kind of CD array library structure, it is characterized in that described CD rack is the annular pallet of a two-way rotation on guide rail, described CD folder is in the radial array of pallet upper edge, and described CD is to be positioned over perpendicular to described pallet direction in the described CD folder; Described CD rack drive unit is positioned at the centre of described annular pallet and is meshed with the inboard of described pallet, and described N is evenly distributed in the described annular pallet outside to mechanical arm and driver.
Described CD and CD folder are divided into N CD group according to the driver number, the corresponding CD group of each driver.In this scheme, the logarithm N of mechanical arm and driver is 2,3,4,5,6 or 8.Pallet rotating range in this CD array library structure is 0 to 360/N degree.
Another kind of CD array library structure of the present invention is characterized in that described CD rack is two the bar shaped pallets that fixed as one by web member that move horizontally on guide rail, evenly distributed CD folder on described two bar shaped pallets; Described N is evenly distributed on the both sides of described bar shaped pallet to mechanical arm and driver, and described CD rack drive unit is meshed with tooth bar on the described web member along described tray motion direction.
The logarithm N of the mechanical arm of such scheme and driver is 2,4,6 or 8.
Another kind of CD array library structure of the present invention is characterized in that described CD rack is a bar shaped pallet that moves horizontally on guide rail, CD evenly distributed on described pallet presss from both sides; Described N is evenly distributed on a side of described bar shaped pallet to mechanical arm and driver, and described CD rack drive unit is positioned at the opposite side of CD rack.
The logarithm N of the mechanical arm of such scheme and driver is 2,3,4,5,6,7 or 8.
CD rack drive unit of the present invention is positioned at a side of CD rack, and this device comprises a power wheel, a pinion wheel and a gear wheel; Described power wheel, pinion wheel, gear wheel mesh successively, and described gear wheel is meshed with CD rack.
According to technique scheme as can be known, the present invention has following beneficial effect:
(1) structure of corresponding N the driver of N mechanical arm, load/unload when making the CD array storehouse realize corresponding CD in the single CD server, thus eliminated the stand-by period delay that produces because of the mechanical arm competition.
(2) CD rack only needs to move in each driver administrative area, has reduced the motion delay of CD exchange; After motion positions of CD rack, serve the dish that changes of N driver simultaneously and operate simultaneously, this structure has been improved the performance in CD array storehouse greatly.
(3) Gu Ding mechanical arm has been simplified the mechanical component of mechanical arm on the one hand, on the other hand by corresponding with driver, makes the increase of mechanical arm not cause the significantly increase of CD array storehouse volume.
(4) Gu Ding mechanical arm utilizes the motion among a small circle of the CD rack of carrying disc to transmit CD, the integral mechanical structure in CD array storehouse is simplified greatly, thereby reduced production cost of products.
