Abstract(in English)	In this paper, we explain the hot replication method. In hot replication, frequenctly accessed(hot)files are replicated on the reserved area of the tape. Reduction of seek length by clustering of hot files and improvement of accessibility to hot data by replication can reduce the response time. After the description of the algorithm of hot replication, its basic performance is shown through simulations. In addition, we clarify its effectiveness for the real applications through the simulation using the access logs of our satellite image database system.
