PROBLEM TO BE SOLVED: To prevent different information processing devices from writing data to the same storage unit by storing the write data in a storage access relay device. SOLUTION: When the storage access relay device receives write data sent from an information processing terminal to a storage device, it stores the data in a write data storage region secured for the information processing terminal that has sent the data instead of sending the data to the storage device. When it receives a data read request sent from the information processing terminal to the storage device, it is determined if a data to be read by the read request exists in the write data storage region secured for the information processing terminal that has sent the read request, etc. If the data exists, the relay device returns the data to be read in the write data storage region to the information processing terminal instead of relaying the read request to the storage device. If the data does not exist, it relays the read request to the storage device. COPYRIGHT: (C)2007,JPO&INPIT
