outline function explanation
DISP.
0
The detection sensitivity for the fault detection function is set in four
1
levels.
2
A fault status is detected when a status where a normal signal can
3
not be detected consecutively for 5 tracks over the following track
values.
0: 1/2
1: 3/4
2: 7/8
3: 15/16
SLOW
The compensation speed in PLL frequency compensation mode is
FAST
set in two levels
0
In the PLL response speed setting, mainly the phase pull-in speed is
|
controlled. The response speed becomes faster with larger values.
9
|
31
0
The strength of the frequency pull-in operation of the PLL phase
1
comparison characteristic expansion function is controlled in four
2
levels. The action is weakest with 0 and strongest with 3.
3
When the data acquisition ratio at the time of special playback is bad,
it can be improved by controlling this parameter.
0
The setting of the PLL response speed controls mainly the frequency
|
pull-in speed. The response becomes faster with larger values.

0
Setting of the frequency offset tolerance value for PLL frequency
|
monitor control
28
The actual tolerance range in regard to the reference frequency is
|
(set value)/10.24%.
127
0
Setting of the frequency offset tolerance value for PLL frequency
|
monitor control
28
The actual tolerance range in regard to the reference frequency is
|
(set value)/10.24%.
127
0
Setting of the threshold value for judging the signal quality after
|
equalization
110
The judgment result for the signal quality is used for adaptive
|
equalization, PLL, fault detection function, and other control.
255
0
Setting of the threshold value for judging the signal quality after
|
equalization
98
The judgment result for the signal quality is used for adaptive
|
equalization, PLL, fault detection function, and other control.
255
0
Setting of the threshold value for the envelope detection signal
|
The envelope detection signal is used for adaptive equalization filter,
16
PLL, and AGC hold control.
|
255
0
In the PLL response speed setting, mainly the phase pull-in speed is
|
controlled.

0
Setting of the initial value of the output voltage adjusting the VCO
|
center frequency
512
Adjustment is performed automatically in standby mode, but the time
|
required for automatic adjustment can be reduced by setting this
1023
value in advance to a suitable value.
0
The automatically adjusted value is read out and set.
|
• Read-out is possible only at the time of EJECT, STANDBY-OFF.
