<p>There is provided a data recording device that, even when data for which a real time property is required is recorded on a recording medium, can record the data in real time by effectively using large and small writing rate regions in the recording medium. The data recording device comprises a buffer function unit (11), a buffer state monitoring unit (13), and a write control unit (16). The buffer function unit (11) temporarily stores data. The buffer state monitoring unit (13) monitors the storage amount of the data stored in the buffer function unit (11). The write control unit (16) writes the data stored in the buffer unit into a first recording region writable with a first writing rate in a recording unit (12) when the storage amount monitored by the buffer state monitoring unit (13) is less than a predetermined value, and writes the data stored in the buffer unit into a second recording region writable with a second writing rate larger than the first writing rate in the recording unit (12) when the storage amount monitored by the buffer state monitoring unit (13) is the predetermined value or more.</p> |
