Problems solved by technology

However, in the existing technologies for reading and writing data using optical disc libraries, when the data to be accessed is distributed on different optical discs, frequent disc replacement operations must be performed, resulting in frequent use of mechanical components of the optical disc library, resulting in mechanical failure of the optical disc library. Reduced component life, increased maintenance costs, and increased data inaccessibility

Abstract

The invention provides an optical disc data reading and writing method. The optical disk library comprises a write buffer area and a read buffer area, wherein the write buffer area comprises a first write request queue for receiving a user write request, the user write request comprises a target optical disk of the user write request, the read buffer area comprises a first read request queue for receiving a user read request, and the user read request comprises a target optical disk of the user read request; recording a user write request into a first write request queue, and merging the userwrite request with a history write request of the same target optical disc. The user read request is recorded in a first read request queue, and the user read request is merged with a history read request of the same target optical disc. The invention reduces the number of disk changing operations, prolongs the life of the mechanical parts of the optical disk library, reduces the maintenance cost,and reduces the inaccessible time of the data.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method for reading and writing optical disc data. Background technique [0002] With the rapid development of social informatization, human society has entered the era of massive data. Compared to magnetic disks, optical disks are a less expensive medium suitable for long-term storage of data. [0003] At present, most optical disk libraries are used for data storage, and each optical disk library can accommodate multiple optical disks, and a certain proportion of optical disk drives is configured. However, in the existing technologies for reading and writing data using the optical disc library, when the data to be accessed is distributed on different optical discs, frequent disk changing operations must be performed, resulting in frequent use of the mechanical components of the optical disc library, resulting in mechanical failure of the optical disc library. Component ...
