Eject/Load are not used usually, because they can be done with
the [EJECT] button.

: Pause is made by executing track jump once per
revolution.

same voltage to the focus drive as that in focus

On this screen, track jump, etc. are executed.
Confirm the sector information (SI) to check the DVD_DL layer
jump direction. Even SI means layer 0, or odd SI means layer 1.
When 1TJ or 32TJ is executed, the tracking is turned on, but the
sled becomes just like initialization.
Also, after executing each jump except 1TJ (and FJ1, 2), the CLVA
mode is set.
The optical system will be damaged if make a jump in
wrong direction FJ0, FJ1, LJ0 and LJ1.
0. FWD 32TJ
: Jump 32 track forward (N track jump).
1. RVS 32TJ
: Jump 32 track reversely (N track jump).
2. FWD 500TJ : Jump 500 tracks forward (fine search).
3. RVS 500TJ
: Jump 500 tracks reversely (fine search).
4. FWD 10KTJ : Jump 10k tracks forward (direct search).
5. RVS 10KTJ : Jump 10k tracks reversely (direct search).

: Adjust tracking offset.
1. TRK. Offset 2 (DVD) : Adjust DVD tracking offset (TO TK-
47 board, IC006). Adjusting range is
(A1 – AF) with
A1 – A7: +25 to +175 mV,
A8 – AF: 0 to –175mV.
2. TRK. Gain 2 (CD)
: Adjust simple AGC of CD tracking.
Adjusting range is (88 – C8) with lower
4 bits fixed.
3. Focus Gain

: Adjust tracking gain.

TRK. Offset : In the tracking offset adjustment for DVD, based
on the peak and bottom data measured by DSP
(IC506), the SSL33P3720A cansels the offset
roughly, then the DSP (IC506) adjusts it finely.
Here, finely adjusted value is set. As adjustment is
made by DSP (IC506) only.
DC component of tracking traverse does not change.
For the CD, only this set value changes.

TRK. Gain : In the tracking gain adjustment for CD, based on
the peak and bottom data measured by DSP (IC506),
the CXA2556 on the sets simple AGC to 5 steps of
–3.2, –1.6, 0, +1.6, +3.2 dB (Auto Tracking Off-
set), then the DSP (IC506) makes setting (Auto
Tracking Gain). Here, DSP (IC506) setting can be
made. In the case of DVD, only DSP (IC506) set-
ting is executed.
