DISC REPRODUCING APPARATUS AND METHOD WITH ADJUSTMENT OF ROTATION SPEED BETWEEN READ POSITIONS

A DISC REPRODUCING APPARATUS SUCH AS A DISC PLAYER AND A METHOD OF THE SAME WHICH OF THE SEEK TIME CAN BE SHORTENED AT THE TIME OF TRAVERSE OF A PICK-UP, BY CALCULATING A LINE SPEED AT A READ POSITION OF A DISC (1) BEFORE THE CHANGE OF THE READ POSITION AND THE TARGET LINE SPEED AFTER THE CHANGE OF THE READ POSITION BEFORE THE PICK-UP (3) IS TRAVERSED, CONTROLLING THE ROTATIONAL SPEED OF A ROTATION DRIVING UNIT (2) TO THAT BEFORE THE CHANGE OF THE READ POSITION SO THAT THE LINE SPEED AT THE READ POSITION AFTER THE CHANGE FALLS WITHIN A MAXIMUM REPRODUCTION LINE SPEED.
