13-13 DVD Servo
(1) Outline
SERVO system of DVD is Composed of Focusing SERVO, Tracking SERVO, SLED and CLV SERVO
(spindle motor servo)
1) Focusing SERVO : Focuses the optical spot output from object lens onto the disc surface. Maintains a uniform
distance between object lens of Pick-up and disc (for surface vibration of disc).
2) Tracking SERVO : Make the object lens follow the disc track in use of tracking error signal (created from Pick-up).
3) SLED Linked SERVO : When the tracking actuator inclines outwardly as the object lens follows the track during
play, the SLED motor moves slightly (and counteracts the incline).
4) CLV SERVO (DISC Motor Control SERVO) : Controls the disc motor to maintain a constant linear velocity
(necessary for RF signal).
