Recording and reproducing device and recording and reproducing method

摘要

Audio DIF blocks containing audio data and video DIF blocks containing video data are extracted by an audio/video extracting unit and respectively recorded in separate storage areas of an HDD. System data and audio auxiliary data are extracted by a system data reconstruction unit and thereafter recorded in a system data storage area of the HDD together with frame information generated by a frame information generating unit. The respective data items are recorded in these separate areas, while the audio auxiliary data is recorded together with the system data, and therefore it is easy to rewrite the data during an editing operation.
