SERVO BLOCK 3-2. Servo Operation at DVD Play 3-2-1. Optical Pickup Control 3-1. General Description of Servo Circuits (1) DVD focus servo The focus error signal output from the optical pickup for DVD (hereinafter referred to as optical pickup) is entered to the TK-47 board IC006: SSI33P3720A A to D ((_ to 3-1-1.
Page 31
The IC506 Servo DSP: CXD8730 on MB-78 board provides the following control the focus servo system. (a) Focus search The optical pickup lens is moved toward a disc to turn on the focus servo. The focus servo loop is turned on when the PI (Pull IN) signal (used for FOK: Focus OK) exceeds the specification (Vc +0.25V) and the FE signal zero-crossing is detected.
Page 33
The FE signal input to IC506 (DSP CXD8730R) is low frequency boosted and gain-adjusted the internal digital filter, and then output from the DSP as the focus drive signal (F OUT _)P) by the D/A converter inside the DSP. The FOUT signal is input to the focus actuator (coil) drive IC (IC363:BA5981). In IC363, voltage amplification, voltage conversion,...

The Servo DSP IC provides the following control in the tracking servo system. (a) Tracking gain adjustment The gain of intemal digital filter of IC is automatically adjusted so that the tracking servo loop gain becomes optimum. Consequently, the optimum gain for each disc to be played can be attained, besides correction of gain variations...

The sled error signal is passed through the digital filter in IC506 (DSP), and output from the DSP as the SOUT ((_)P) signal from the D/A converter. The SOUT signal is input to DVI ((_P) of the sled drive IC (IC302:LA6527N). The sled drive IC incorporates a speed (motor rotation speed) feed back control using the Hall element.
3-2-3. Spindle Control This section describes the flow of control signals in the spindle servo during DVD playback. The CLV control signal is generated from the RF signal obtained from the optical pickup in ' IC806 (CXD1865) to generate the two servo error signals-disc CLV speed error (MDSO (_ P) and CLV phase error (MDPO (_)P).

(2) Tilt offset adjustment minimizing jitter To optimize RF during DVD playback (excluding search), the jitter (JITTER:time:axis fluctuation of the RF signal) is measured, offset is added to the tilt servo loop, and the jitter is minimized. As jitter is adjusted at shipment, normally this adjustment is not required during playback.

3-3-2. CD Sled Control CD sled control is exactly the same as the DVD. However settings in IC506 (DSP:CXD8730R) differ. 3-3-3. CD Spindle Control As the RF signal is processed inside IC806 (CXD1865), the process from the ARP is the same as the DVD.
Disc loading, unloading, and chucking operations are performed with one DC motor. Its block diagram is dhown in Figure 3-19. 3-4-1. Motor Driver The system controller IC (IC805) controls the open and close of the tray. It monitors sensors of the mechanism conti:ols the operations of the tray motor via the L G/A IC (IC804).
3-5. Differentiation of Disc Type This series can determine three types of discs (CD/DVD-SL/DVD-DL) at one time when performing focus-search. 3-5-1. CD/DVD Differentiation The pit shape and track pitch are quite different between CD and DVD. Because of this difference, TE is not generated even if a large laser spot for CD is shot at a high density disk such as DVD.
