Abstract:
A data recording/reproducing apparatus comprising:recording means for recording on a recording medium recording data and parity data for the recording data;parity storage means for storing the parity data prior to being recorded on the recording medium;reproducing means for reproducing the recording data and the parity data recorded on the recording medium;error correction means for correcting the reproduced recording data based on the parity data reproduced by the reproducing means;detection means for detecting a number of times error correction has been performed on the reproduced recording data by the error correction means when the recording data and the parity data are recorded by the recording means;recording confirming means for comparing the detected number of times error correction has been performed to a pre-set threshold value and when the detected number of times error correction has been performed is less than said pre-set threshold, said recording confirming means compares the reproduced parity data to the parity data stored in the parity storage means in order to determine whether the recording by the recording means has been done correctly; andre-recording controlling means for controlling the recording means so that, if the recording confirming means does not determine that the recording by the recording means has been done correctly, the recording data is re-recorded by the recording means.
