“…In the age of big data, facing the storage problem of massive data, it is impossible to meet the market demand of big data storage only by using a single storage medium [1][2][3] . Rational use of storage devices and design of effective storage methods is an important research direction of data storage.…”

There are some advantages and disadvantages when using cold storage medium and hot storage medium separately. To solve this problem, the disk array is used as the disk storage layer, and the Blu-ray disc library is used as the optical storage layer, and a multi-level distributed object storage system is formed by reasonably combining cold storage and hot storage. Then based on the multi-level distributed object storage system, an effective data storage method is designed. The functions of data reading, recording and reverse recovery are realized to provide users with effective storage services and improve data storage efficiency and resource utilization. Finally, the system is tested to verify the feasibility and effectiveness of the system.

“…Permanent magnetic materials with high coercivity and high remanent magnetization have wide application fields including cost-effective electric motors, long-lasting data recording media, high frequency communication devices, electroacoustic devices, etc. [1][2][3][4][5]. Among these, strontium hexaferrite (SrM; SrFe 12 O 19 ) with magnetoplumbite structure comprises one of the most important class of highperformance magnetic materials.…”

“…Among these, strontium hexaferrite (SrM; SrFe 12 O 19 ) with magnetoplumbite structure comprises one of the most important class of highperformance magnetic materials. SrM exhibits a large magnetocrystalline anisotropy constant (K 1 ~ 3.6 × 10 6 erg/cm 3 ) and a high saturation magnetization (M s ~ 74 emu/g) suitable for permanent magnet [6].…”

Aluminum-substituted M-type strontium hexaferrite (SrM-Al, SrFe12−xAlxO19, 0 ≤ x ≤ 4) with uniform microstructure and excellent magnetic properties was synthesized by conventional ceramic processing based on solid state reaction. Coercive field was highly enhanced by heavy doping with Al3+ although magnetization was significantly reduced. However, formation of coarse microstructure and poor development of Hc with low level doping of Al3+ disturbed practical application. To promote phase formation and to suppress growth of coarse grains which were induced by incorporation of Al3+ ions, SrM-Al ceramics was processed with NaOH. Such Na-assisted processing of SrM-Al reduced formation of non-magnetic phases and assisted development of uniform fine grains. In addition, the large residual strain by Al3+ doping was partially relieved by the same approach. As a result, saturation magnetization of SrFe12−xAlxO19 was remarkably enhanced and the BHmax of randomly oriented hard magnetic ceramics was improved to 1.23MGOe by concomitant addition of Na and Al ions.
