Replacement

of

the

pickup

assembly

@

Before

removing

the

pickup

assembly

be

sure

to

solder

~bridge

where

indicated

in

the

inset

(Fig.

4-1)

to

prevent

the

laser

diode

from

being

electrostatically

damaged.

After

replacing

the

pickup

assembly,

be

sure

to

unsolder

the

antistatic

bridge.

Or

else

the

laser

diode

does

not

function.

@

Before

servicing

the

pickup

assembly

be

sure

to

prevent

electrostatic-inducer

destruction

by

grounding

not

only

test

equipment

in

use

but

also

yourself

as

shown

in

Fig.

4-2.

*

Electrostatic

charge

drastically

shortens

the

operating

life

of

the

laser

diode

or

possibly

results

in

its

destruction.

@During

the

transportation,

mounting

and

dismounting

of

the

assembly,

support

with

your

fingers

at

points

A

and

B

as

shown

in

Fig.

4-3.

Be

particularly

careful

not

to

touch

the

actuator,

photosensor

and

LD

plate

and

do

not

apply

force

to

them.

@

Soldering

must

be

done

quickly

less

than

30W,

@Laser

beams

are

similar

to

Don’t

look

at

the

beams

directly

and

keep

your

eyes

at

least

30cm

away

from

them.

@Don’t

touch

the

objective

with

@If

objective

becomes

dirty,

will

deteriorate.

To

clean

the

objective,

moisten

a

good

cleaning

tissue,

such

as

made

by

KODAK,

in

isopropyl

alcohol

and

wipe

the

gently.

Wipe
