Video tape recorder including tracking apparatus. |
摘要 |
<p>A video tape recorder performs tracking corrections by moving video heads using an electric-mechanical transducer vertically with respect to the scanning direction of video tracks. The video tape recorder measures cycles of synchronizing signals included in reproduced video signals, so that the electric-mechanical transducer shifts the video heads to get regular measuring, thereby allowing the video heads to accurately scan the video tracks.</p> |
