Embodiment 1

[0074] The present invention provides a near-line optical disc library, which will be described in detail below in conjunction with the accompanying drawings. For simplicity, only those elements relevant to the subject matter described herein are shown. The overall nearline optical disc library can have many other configurations and use many other types of equipment.

[0075] figure 1 It is the front view of the manipulator provided by the present invention in the near-line optical disc library in the low-density storage area, figure 2 It is the front view of the manipulator provided by the present invention in the near-line optical disc library in the high-density storage area, such as Figure 1-2 As shown, a near-line optical disc library includes a cabinet 1, and the cabinet 1 is provided with a low-density storage area 2, a high-density storage area 3, an optical drive group 4 and a robot assembly 5; the low-density storage area 2 includes a first optical disc magazine ...

Embodiment 2

[0095] Figure 11 is a flow chart of the data hierarchical storage method provided by the present invention, such as Figure 11 As shown, the present invention provides a data hierarchical storage method, comprising the following steps:

[0096] S1: When the data of the target disc becomes cold data, the target disc is taken out from the specified pull-out type disc case 211 by the manipulator assembly 5 and put into the group type disc case 311;

[0097] Please refer to Embodiment 1, the nearline optical disc library is configured with a low-density storage area 2 and a high-density storage area 3, the low-density storage area is used to store near-line data, the low-density storage area 2 includes a first optical disc magazine, the first optical disc The magazine is equipped with several disc cartridges 211; the high-density storage area is used to store cold data. The high-density storage area 3 includes a second optical disc magazine 31, and the second optical disc magazi...

Embodiment 3

[0105] Figure 14 is a structural block diagram of the data hierarchical storage system provided by the present invention, such as Figure 14 As shown, the data hierarchical storage system provided in this embodiment includes a nearline optical disk library 301 , a data classification module 302 , a data migration module 303 , an offline optical disk library 304 and a data retrieval module 305 .

[0106] The data grading module 302 is used for when the data of the target disc becomes cold data, the target disc is taken out from the specified disc case 211 by the manipulator assembly 5 and put into the grouped disc case 311; 211 is accommodated in the first disc magazine compartment of the nearline disc library 301 , and the grouped disc magazine 311 is accommodated in the second disc magazine compartment 31 of the nearline disc library 301 .

[0107] The data migration module 303 is used for taking out the grouped optical disc magazine 311 from the second optical disc magazin...

Abstract

The invention discloses a near-line light disc library comprising a cabinet. A CD driver group, a low-density storage area, a high-density storage area and a mechanical arm assembly are arranged in the cabinet. The CD driver group consists of a plurality of CD drivers that can carry out reading and writing on a light disc in parallel or independently. The low-density storage area includes a firstlight disc box cabin with a plurality of drawing piece type light disc boxes. The high-density storage area includes a second light disc box cabin with a plurality of grouped light disc boxes. Openings are formed in the sides of the first light disc box cabin and the second light disc box cabin. The mechanical arm assembly faces the openings formed at the sides of the first light disc box cabin and the second light disc box cabin and is used for capturing a target light disc in the selected cabin and conveying the target light disc to a predetermined position. In addition, the invention also discloses a data grading storage method and a data grading storage system. Therefore, the low-density storage area can be utilized fully; and the data storage cost and the work intensity of data transfer are reduced.

Description

technical field [0001] The invention relates to the technical field of optical storage, in particular to a near-line optical disc library, a data hierarchical storage method and a data hierarchical storage system. Background technique [0002] Hierarchical data storage is based on the locality of data access. Data objects are stored in different levels of storage devices, so that important data and commonly used data can be accessed in the shortest time, and rarely used data can be backed up in cheap mass storage. , and realize the automatic migration of data objects between different levels of storage devices through hierarchical storage management software. [0003] In the hierarchical data storage structure, high-cost and high-speed devices are used to store frequently accessed important information, while lower-cost storage resources are used to store less frequently accessed information. Data from generation to storage, utilization, archiving, and finally deleted beyon...
