<p>A track jumping scanning control section (300) in an optical disc device is provided with a header cycle calculating circuit (341A), which calculates a header cycle from a time when an optical beam is applied on a header region in a certain sector in an optical recording medium to a time when the optical beam is applied to a header region in a subsequent sector. The control section is also provided with a comparing circuit (342), which compares the length of the header cycle calculated by the header cycle calculating circuit with a time required for track jumping scanning, and a delay control circuit (343), which controls delay of starting timing of the track jumping scanning, based on the comparison results obtained from the comparing circuit.</p> |
