DIGITAL DATA RECORDING DEVICE AND RECORDING METHOD

摘要

When dividing digital data of variable bit rate into continuous areas of unit periods, it is possible to suppress generation of fragmentation. When the data amount of the buffer memory is equal to or above the unit period, the digital data is read out from the buffer memory by the unit period and the digital data which has been read out is recorded as a continuous area (step 106). When the data amount of the buffer memory is smaller than the unit period, the data amount is predicted from the time corresponding to the digital data amount smaller than the unit period and from the length of the unit period (step 112). The digital data of the unit period is recorded in a recording-enabled area capable of continuously recording the digital data of the predicted data amount (step 106).
