Data recording apparatus and method

摘要

A recorded state monitoring portion 4 monitors a state where a recording instruction to a storage device 1 is executed. A recording managing portion 3 judges whether or not the result of the monitoring by the recorded state monitoring portion 4 satisfies a predetermined condition, to issue the recording instruction to the storage device 1 when the result of the judgment is affirmative, while issuing a recording instruction to an auxiliary storage device 2 when it is negative. Data continuously fed are recorded upon being shared between the storage device 1 and the auxiliary storage device 2, so that the apparent recording speed is equal to the sum of the recording speed of the storage device 1 and the recording speed of the auxiliary storage device 2, thereby making higher-speed recording possible.
