Claim:
A data recording device having incorporated therein or connectable thereto a plurality of storage media for digital-recording video data and/or sound data, and comprising an input device for giving a command to start and cease recording data and a control circuit for controlling data recording to the plurality of storage media, the control circuit comprising: means for starting recording data to one storage medium A at a first point of time when a command is given to start recording data; first judging means for judging whether the remaining capacity of the one storage medium A is not greater than a given capacity value x during data recording to the one storage medium A; first control means for starting recording data to another storage medium B at a second point of time when it is judged that the remaining capacity of the one storage medium A is not greater than a given capacity value x, concurrently with the data recording to the one storage medium A; second control means for terminating recording of data to the one storage medium A at a third point of time when a capacity of the one storage medium A is full or is not greater than a given capacity; second judging means for judging whether, at a fourth point of time when a command is given to cease recording the data or data recording is automatically ceased to said another storage medium B, space capacity of said another storage medium B is greater than a data amount recorded on the one storage medium A from the first point of time to the second point of time; and third control means for, when it is judged that space capacity of said another storage medium B is greater than a data amount recorded on the one storage medium A, copying automatically or in response to a user's command the data recorded on the one storage medium A from the first point of time to the second point of time to said another storage medium B, and managing a series of data from the first point of time to the fourth point of time as one file.
