Abstract:
1. A data recording equipment for recording data including sub-code data by irradiating an optical disc with a laser beam and for interrupting the recording of data when detecting an external shock that hinders the recording of data or when predicting the occurrence of a buffer underrun error, the data recording equipment comprising: a counter for counting execution of recording data on the optical disc in units of bits and generating a count value indicating the amount of data that is recorded; and a control unit connected to the counter for holding the count value of the counter immediately before the interruption when the recording of data is interrupted and re-irradiating a position on the optical disc, on which data prior to the data recorded immediately before the interruption is recorded, with the laser beam; wherein the control unit controls restart of the recording of data based on the held count value while recognizing the position of data on the optical disc using the sub-code data.
