Abstract
To prevent a decrease in the window margin due to reproduced signals having asymmetrical waveforms in a magnetic recording and reproducing apparatus, data in which peak shifts occur are recorded in the SYNC regions in the data format for the recording medium in accordance with the recording method. In data read operation, by detecting the data recorded in the SYNC regions, the center of the data window signal is shifted by a desired peak shift amount.
