ABSTRACT:
A recording/reproducing apparatus detecting a starting position of each data recording block or sector on a data recording medium, such as an optical disk. A VFO pattern and a CRC code are recorded at a starting position of each of the sectors. The VFO pattern and the CRC code are utilized for detecting a starting position of each sector with no predetermined pattern or sector mark, on the recording medium, which is dedicated for the starting position detection. This improves data formatting efficiency of the recording medium while maintaining the accuracies of automatic focusing and tracking even in a system employing pit-edge recording/reproducing.
