5-4-1 Outline
SERVO system of DVD is divided into Focusing SERVO, Tracking SERVO, SLED Linked SERVO and CLV
SERVO (DISC Motor Control 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).
