A configuration, in which access processing such as data recording from an external device to the archive device can be efficiently performed, is implemented. A data processing section that performs a data recording processing control on a library, which is a data storage section of the archive device is provided. The data processing section saves record data in the local cache section in response to an input of the data recording request from the external device to the library, and outputs a recording processing completion notification to the external device. Further, an elapsed time after the saving in the local cache section is measured, and after the saving in the local cache section, the record data is transferred from the local cache section to the library and recorded after a pre-specified postponement time elapses.
