Zusammenfassung:	PROBLEM TO BE SOLVED: To set a timeout value corresponding to AV data and the other data, relating to a data recording device which writes/reads the AV data as well as other data on/out of a plurality of HDDs based on the command from an upper-class control device. SOLUTION: The data recording device includes a control part 11-2 which performs: a process for setting a limit on the time duration corresponding to the number of sectors required through the command received from a control device 11-1 of a higher order; a process for issuing a command corresponding to the command received from the control device 11-1, with a set limit time specified, to HDD controllers 14-1 to 14-6; and a process for responding to the control device 11-1 based on the result of writing/reading only with such HDD in which the process of writing/reading has been completed within the limit time among HDDs 15-1 to 15-6.
