Abstract
When data is recorded to a recording medium having a sector structure, the data is recorded with synchronization signals (frame marks) placed at a constant interval for use during data reproduction. When the data is then reproduced from this recording medium, these frame marks are detected to demodulate the data based on the detected signals.
