The special jig (J-2501-149-A) is useful for checking the waveform of the BD board. The names of terminals and the checking items to
be performed are shown as follows.

GND : Ground
I+3V : For measuring IOP (Check the deterioration of the optical pick-up laser)
IOP : For measuring IOP (Check the deterioration of the optical pick-up laser)
TEO : TRK error signal (Traverse adjustment)
VC

: Reference level for checking the signal

RF

: RF signal (Check jitter)

Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent.
Details of the procedures are described in “5 Electrical Adjustments”.

• 0.9 mW power

Specified value : 0.84 to 0.92 mW

• 7.0 mW power

Specified value : 6.8 to 7.2 mW

lop (at 7mW)

• Labeled on the optical pickup

Iop value ± 10mA

• Error rate check

Specified value : For points a, b, and c
C1 error : About 200
ADER : Below 2

• Error rate check

Specified value:
a. When using test disc (MDW-74/AU-1)

C1 error : Below 80
ADER : Below 2

b. When using check disc (TDYS-1)

C1 error : Below 50

• CPLAY error rate check

Specified value:
C1 error : Below 80
ADER : Below 2

Laser power check
(6-1 : See page 28)

Focus bias check
(6-2 : See page 28)

C PLAY check
(6-3 : See page 28)

Self-recording/playback
check
(6-4 : See page 28)

Criteria for Determination
(Unsatisfactory if specified value is not satisfied)

• Clean the optical pick-up
• Adjust again
• Replace the optical pick-up

• Replace the optical pick-up

• Replace the optical pick-up

• Replace the optical pick-up

If always unsatisfactory:
• Replace the overwrite head
• Check for disconnection of the circuits around the

overwrite head

If occasionally unsatisfactory:
• Check if the overwrite head is distorted
• Check the mechanism around the sled

Measure if unsatisfactory:

The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for
adjustments.
When performing adjustments, use the specified values for adjustments.
