PROBLEM TO BE SOLVED: To increase efficiency of data transfer relating to an interface technology for connecting a computer and a device. SOLUTION: In a data transfer system including an interface section (200) which can interface a host (100) and media (300) which can be accessed by this host, the interface section is provided with; a storage section (202) that can hold the data written in the media from the host, or the data read from the media; and controllers (201, 203, 204, 205 and 206) which can discriminate whether the data concerning access to the media from the host exists in the storage section or not, and can omit writing duplicated data to the media. Also in reading data, read operation from the media can be omitted by using the data in the storage section. Thereby, efficiency improvement in data transfer is attained. COPYRIGHT: (C)2006,JPO&NCIPI
