Embodiments of the present application disclose a data reading method and device, electronic equipment and computer readable storage medium, and relate to the technical field of data reading; the method comprises the following steps: when a reading request of Blu-ray disc access library for Blu-ray data is received, it is detected whether the Blu-ray data is included in a cache reading channel; when the Blu-ray data is not included in the cache reading channel, the whole target Blu-ray data containing the Blu-ray data is read from a NAS device based on the cache reading channel, and the whole target Blu-ray data is cached to the cache reading channel; the Blu-ray data is cut out from the whole target Blu-ray data based on an offset position corresponding to the reading request, and the Blu-ray data is returned to the Blu-ray disc access library. In this way, the present application can request the whole data of large granularity from the NAS device, thereby reducing the number of network requests and fully utilizing the link bandwidth.

The invention discloses a monitoring video stream automatic filing and optical disk storage system and device, and the system comprises a blue-ray optical disk library with a built-in management server, a video stream automatic capturing and filing system for executing the instruction of the built-in management server, and a storage management system. The video stream automatic capturing and filing system is used for capturing a video stream from the front-end monitoring storage device and performing format conversion and compact disc recording on the video stream so as to file the video into a blue-ray disc jukebox and realize storage of the monitoring video; the storage management system is used for collecting optical disk data stored in the blue-ray optical disk jukebox and archived data and video data in the video stream automatic capturing and archiving system, and performing unified scheduling and management on the optical disk data, the archived data and the video data to complete management and retrieval of monitoring videos; according to the method, the problems of high cost, high risk and inconvenience in subsequent management and retrieval of important video data stored in a magnetic storage medium for a long time can be solved.

The application discloses a data migration method based on a blue-ray disc library, relates to the technical field of data migration, and determines data to be migrated as migration data, and transmits the migration data in the original storage medium to a temporary storage area of a blue-ray disc library server through a data transmission channel; after the migration data is received, the migration data is uploaded to a specified storage position of the blue-ray disc library server, and a burning traction item corresponding to the specified storage position is set. The application can sequentially store and manage the migration data through a traction chain, can realize the orderly burning of a large amount of migration data, avoids data confusion, can safely acquire the migration data through a traction package, the traction chain and the corresponding traction package can guarantee the safety of the migration data, reduce the burning abnormality caused by data changes due to network interference, and have a good migration data management effect.

The invention belongs to the technical field of optical storage, and discloses a super-resolution optical hard disk (HORD) device based on a nanometer tip array. According to super-resolution recording, the size of a near-field light spot is determined by the distance between a nanometer tip and a disk (not the laser wavelength), the typical size can reach 10-50 nm, the resolution is improved by 5-10 times compared with traditional optical storage (larger than or equal to 200 nm), and the optical storage efficiency is greatly improved. The capacity of a single disc can reach a TB level (the capacity of a traditional blue-ray disc is about 100GB); the aerodynamic (or electromagnetic) suspension structure of the floating block can adapt to a high-speed motion scene (such as a flying mode of a magnetic head in magnetic storage), and dynamic stability of nanoscale spacing is ensured by combining the spacing regulation and control module; and the distance regulation and control module monitors and adjusts the suspension distance (the precision is less than or equal to 1nm) in real time through a sensor, so that the influence of thermal fluctuation and mechanical vibration on near-field light spots is effectively inhibited, and the recording and reading accuracy is ensured.

The invention discloses a data migration method based on a blue-ray disc jukebox, which relates to the technical field of data migration, and comprises the following steps: determining data to be migrated as migration data, and transmitting the migration data in an original storage medium to a temporary storage area of a blue-ray disc jukebox server through a data transmission channel; and after receiving of the to-be-migrated data is completed, uploading the to-be-migrated data to a specified storage position of the blue-ray disc jukebox server, and setting a recording traction item corresponding to the specified storage position.
