PROBLEM TO BE SOLVED: To provide an information recording device which improves efficiency, when recording data to a disk recording medium using a nonvolatile memory as a cache, in writing data recorded in the nonvolatile memory to the disk recording medium, prevents data errors as much as possible and keeps high reliability of data, and to provide a control method therefor. SOLUTION: The information recording device includes a setting means 16l which sets the priority order of writing asynchronous data to the disk recording medium 13 depending on the state of each recording area in which the asynchronous data of the nonvolatile memory 15 is recorded when writing asynchronous data not recorded in a disk recording medium 13 among data recorded in the nonvolatile memory 15 to the disk recording medium 13 by a control means 16 which controls data transfer among the disk recording medium 13, the nonvolatile memory 15 and an external device.
