Discman Optic Group

[Daniele - Skrauso]

Hi all,
I have a discman with problems with the Mechanical/Optical group (the one
including the lens and the driving motors). It's detached from the board,
and connected to it by a 6-wires connector. It really looks like it's
standard.. do you know if it truly is and if it was possible to get another
mechanical/optical group from another discman to substitute it?

Thanx

Daniele

I have a discman with problems with the Mechanical/Optical group (the one

What kind of problems are you having?

What is the make and model of the Discman.

It's possible to replace the traverse assembly, but it must be an exact
replacement. The part numbers for the replacement optical pickup alone must
match those of the one it's replacing.

It's almost impossible to swap a traverse from a Philips portable CD player
into a Sony CD player because of significant differences of the parts, despite
the fact that they perform the same function.

It is possible to swap parts from, say, one Sony CD player to another Sony CD
player as many CD players of the same brand share the same parts throughout
different models. But, again, the parts must be exact replacements and not all
models are interchangeable with one another. For example, while you could swap
an optical pickup from a Sony CDP-101 to a Sony CDP-610ES, you cannot swap an
optical pickup out of a Sony CDP-270 into a Sony CDP-610ES.

In addition, the optical pickup block itself is usually connected to the player
electronics through the use of a multi-conductor ribbon cable. This ribbon
passes the data picked up from the disc as well as feedback for the servo
control. This ribbon connector also feeds power to both the laser for reading
the disc and the voice coil actuators for controlling the objective lens focus
and tilt to control the beam. The traverse assembly should be connected to the
player electronics with at least one more element than just the six wire plug
you've described. - Reinhart

Thanx a lot for your extended explanation!
After further testing I could fix the problem: there was a stability issue
in the optical block.. it's poorly set into its place by 3 shitty rubbers.

Bye and thanx again

In other words, the rubber dampeners have deteriorated to the point where they
are no longer supporting the traverse assembly, affecting how the disc is being
read. - Reinhart
