Abstract
An editing system measures the servo-lock period in every pre-view operation. Pre-roll time is updated based on the measured servo-lock period. The magnitude of rewinding of the tape is thus adjusted on the basis of the updated pre-roll time. By up-dating the pre-roll time in accordance with servo-lock period measured in actual operation, the pre-roll time can be set at a minimum value to be determined according to the servo-lock period. Therefore, the tape does not over shoot the optimum queuing position and the period preceding the cut-in point during pre-view operation can be kept short.
