<p>PURPOSE: To execute precise tracking based on calculation after tracking data at the time of the other mode is calculated through the use of tracking data at the time of a reproduction mode since the change of tracking at the time of the reproduction mode and the change of tracking have mutual relevance. CONSTITUTION: Present tracking data is transmitted after automatic tracking at the time of the reproduction mode is executed and the conversion value of tracking data being a difference between present tracking data and initial tracking data is calculated. The function of conversion data is set at the time of two-fold speed reproduction and slow mode by using the conversion value of such tracking data. When initial tracking data is transmitted at the time of two-fold speed reproduction and slow mode, the function of conversion data and initial data at the time of two-fold speed reproduction and slow mode is added and it is transmitted as tracking data.</p> |
