6-3. SACD (DL) DISC OPERATION CHECK
(• Perform as necessary)
The stability of the set can be checked by repeating the combined
operation of focus jump (layer 0
t
1, layer 1
t
0) and access to
the most inward track
y
most outward track by the set number of
times or until an error occurs using the dual layer HD disc, DL
disc.
A set of operation including an access to the layer 0 (most inward
track)
t
layer 0 (most outward track)
t
focus jump (layer
0
t
1)
t
layer 1 (most outward track)
t
layer 1 (most inward
track)
t
focus jump (layer 1
t
0) is carried out repeatedly by the
set number of times.
Checking Method:
1. After setting the test mode, rotate the
[ AMS ]
dial to
select “92. SET CHECK” and press the
[ AMS ]
dial
to enter.
2. When “SET TEST START” is displayed, rotate the
[ AMS ]
dial clockwise by 3 clicks to display “2.
F.JMP CHECK?”.
3. Press the
[OPEN/CLOSE]
button to open the tray, and place
the DL disc.
4. Press the
[ AMS ]
dial to load the tray into the set.
5. “NOW SET UP” will be displayed and the DL disc setup will
start. (It takes about ten and several seconds to set up the disc
as two layers of layer 0 and layer 1 are adjusted)
6. At the completion of setup, “F.JUMP TIMES” will be dis-
played.
7. Rotate the
[ AMS ]
dial clockwise by 5 clicks to display
“5”. (If 5 sets of operation is executed *1)
8. Press the
[ AMS ]
dial, and the check will start.
9. Immediately when the check finished, “UP MAX
ssss
”
t
“UP AVE
ssss
”
t
“DW MAX
ssss
”
t
“DW AVE
ssss
”
t
“F.JMP OK
[TIMES]
”
will be displayed repeatedly. (
s
denotes the measured value
in msec)
UP MAX: Max time required for layer 0 (most inward
track)
t
layer 0 (most outward track)
t
focus jump
(layer 0
t
1)
UP AVE:
Average time required for layer 0 (most inward
track)
t
layer 0 (most outward track)
t
focus jump
(layer 0
t
1)
DW MAX: Max time required for layer 1 (most outward
track)
t
layer 1 (most inward track)
t
focus jump
(layer 1
t
0)
DW AVE: Average time required for layer 1 (most outward
track)
t
layer 1 (most inward track)
t
focus jump
(layer 1
t
0)
Specified value: 7000 msec or less (if no error occurred)
If an error occurred due to defocusing during the checking,
refer to the following error list. (64 page)
10. Press the
[OPEN/CLOSE]
button, and the disc will be ejected
and the check will finish. Also, if the
[ AMS ]
dial is
pressed in step 9, “2. F.JUMP CHK OK” will be displayed.
Then, if the
[ AMS ]
dial is again pressed, “2. F.JMP
CHECK” will be displayed instantaneously and a recheck is
enabled from the step 5 in the same manner.
*1 Setting arbitrary number of times instead of 5 allows the check-
ing to be repeated by the set number of times. Also, setting 0
(zero) allows the aging check to be repeated until an error oc-
curs.
6-4. HYBRID DISC OPERATION CHECK
(• Perform as necessary)
This test checks the auto adjustment time required when the disc
is switched between HD (SACD) layer and CD layer. This test is
conducted to check the stability in switching from CD to SACD,
or SACD to CD in the HYBRID disc.
A set of operation including CD layer stop state
t
HD layer auto
adjustment
t
HD layer TOC reading
t
HD layer stop state
t
CD
layer auto adjustment
t
CD layer TOC reading
t
CD layer stop
state is repeated by the set number of times.
Checking Method:
1. After setting the test mode, rotate the
[ AMS ]
dial to
select “92. SET CHECK” and press the
[ AMS ]
dial
to enter.
2. When “SET TEST START” is displayed, rotate the
[ AMS ]
dial clockwise by 4 clicks to display “3.
HYB CHECK?”.
3. Press the
[OPEN/CLOSE]
button to open the tray, and place
the HYBRID disc.
4. Press the
[ AMS ]
dial to load the tray into the set.
5. “NOW SET UP” will be displayed and the HYBRID disc setup
will start. (It takes about several seconds to set up the disc *1)
6. At the completion of setup, “CHANGE TIMES?” will be dis-
played.
7. Rotate the
[ AMS ]
dial clockwise by 5 clicks to display
“5” (if 5 sets of operation is executed *2)
8. Press the
[ AMS ]
dial, and “START” will be displayed
and the check will start. During the check, the following will
be displayed.
“CD—>HD” display: Time from switching from CD layer to
HD layer up to start of play is measured.
“HD—>CD” display: Time from switching from HD layer to
CD layer up to start of play is measured.
9. Immediately when the check finished, “CD MAX
ssss
”
t
“CD AVE
ssss
”
t
“HD MAX
ssss
”
t
“HD AVE
ssss
” will be displayed
repeatedly. (
s
denotes the measured value in msec)
Specified value: 10000 msec or less (if no error occurred)
If an error occurred due to defocusing during the checking,
refer to the following error list. (64 page)
10. Press the
[OPEN/CLOSE]
button, and the disc will be ejected
and the check will finish. Also, if the
[ AMS ]
dial is
pressed in step 9, “HYB CHK OK” will be displayed. Then, if
the
[ AMS ]
dial is again pressed, “HYBRID CHECK”
will be displayed instantaneously and a recheck is enabled from
the step 5 in the same manner.
*1 “NOW SET UP” display may continue for several minutes
and an error may be displayed depending on the discs. In this
case, press the
[ AMS ]
dial again.
*2 Setting arbitrary number of times instead of 5 allows the check-
ing to be repeated by the set number of times. Also, setting 0
(zero) allows the aging check to be repeated until an error oc-
curs
