Abstract： [Purpose/significance] The choice of storage carrier is the key issue for long-term preservation of digital archival resources. Magnetic-optical-electric hybrid storage technology combines advantages of magnetic storage, optical storage and electric storage. Exploring the application of this technology in the long-term preservation of digital archival resources creates great value in theoretical research and practical guidance.[Method/process] Based on the summary of the current research status of long-term preservation of digital archival resources, this paper proposed that carrier selection is an important issue in the long-term preservation of digital archival resources; combing the relevant standards, practical applications, common carrier suitability and performance requirements of long-term preservation of digital archival resources; introduced and analyzed the advantages of magnetic-optical-electric hybrid storage technology in long-term preservation of digital archival resources;and taking the application of Archives of Chinese Academy of Sciences as an example, this paper introduced the application and exploration of magnetic-optical-electric hybrid storage in long-term preservation of digital archival resources.[Result/conclusion] Although magnetic-optical-electric hybrid storage has shortcomings such as incomplete standards, as well as software and hardware that need to be improved, it has many advantages such as green energy saving, low Total Cost of Ownership, long storage life, safety and reliability, and supporting for multiple backup modes. It is the best choice to meet the characteristics of digital archival resources and long-term preservation requirements.
