APPARATUS AND METHOD FOR CONTROLLING THE ROTATION VELOCITY OF AN OPTICAL DISC |
摘要 |
<p>Method and apparatus for controlling the rotation velocity of an optical disc in a wide range of velocities, including low velocities. In a first range of velocities, a first sensor, for example an EMF sensor, is used to control the commutation moments of a turntable motor. For velocities outside the first range, a periodic control signal based on a periodic second signal generated by a second sensor and a mapping between the first and second periodic signal are used. The method and the apparatus are suitable for LightScribe applications.</p> |
