A problem with a cd player

[Gaetan Mailloux]

Hello

A friend of mine do have a kenwood DP-460 cd player with a cd playing problem.

My friend was sure that the laser was burned, but I
decide to test his Kenwood cd player, wen I use commercial music cd it
work perfect, but wen I use burned cd-r music, this Kenwood cd player can
not play more than 7 track, after 7 track it do jerky sound with the
music, it look like it can not follow those track.

Any hints of what could be the problems ?

Here is a link to a part of the schematic of the kenwood DP-460 cd player.

You don't need a schematic to figure out that many CD players have
problems with CD-R discs. I've seen this on my own equipment. Depends on
the type of CD-R discs *and* the recorder they were burned on.

Likely to be poor laser performance. CD-R discs are nowhere near as
reflective as commercial 'pressed' types, and many players that were not
specifically designed to cope with them, struggle, particularly if the laser
is marginal, or even dirty. Have you, as a first move, tried cleaning the
lens ? (properly with alcohol etc, not a cleaner disc).

As you get further into a disc, its rotational speed falls to maintain CAV.
If the performance of the spindle motor is anything less than perfect, its
speed can be minutely erratic. If the performance of the laser is down as
well, then when you combine these factors, which are typically present in
any player older than a few years, the result tends to be poor tracking
performance / general playability problems on late tracks, and this will be
exacerbated by use of CD-R discs.

Home recorded CDs ain't the same as commercial ones and some CD players
simply can't cope with them. And re-recordable seem to be more prone to
these problems than use once types. Think it's to do with the type of
reflective layer. Strangely, very old ones seem ok - I have an early
Philips dating from the '80s which does. Newish ones should be ok too.
It's the inbetweens that can be a problem.

Try burning the CDs at a slower speed.

I agree - the OP should definitely clean the laser. Other maintenance, such
as cleaning and lubricating other moving parts - rails, gears, motor
spindles, etc, is also indicated. If after cleaning and maintenance issues
are resolved the problem persists, another brand of CD-R's might help, or
the laser may just be deteriorated to that point, especially if in a dusty
and/or smoky environment.

Perhaps because audio CD's are CLV...

I hate to jump on you, Arfa, because you are incredibly knowledgable, but
CDs are CLV, not CAV.

Also, technically speaking, it should be "further out of a disc" (as disks
are read from the inside out).

I did try other cd-r brand but the problems still there.

Yes indeed. See my reply to Mark. As far as "further into a disc" goes,
we're just looking at it from two different angles. You are looking at it
from the physical side, as indeed, the laser does read from the inside out.
I was looking at it from the time angle - as in further into the disc's
musical content.

If you have access to an oscilloscope, the HF "eye" pattern can be observed,
and may be noisy. This would account for the deteriorated performance first
on CD-R's. As previously noted, this is often the result of dust and smoke
contamination. The finest particles get inside the laser, and settle on the
turning mirror as a fine film. This diffuses the reflected laser light
coming back off the disc before it can really be read. It is sometimes
worthwhile to adjust the Focus Offset for maximum amplitude as viewed on the
scope. If it makes a difference of about 20% or more, this may solve your
problem, at least for the short term.

Same problem here. Gets frustrating at times. I'll stop mid-sentence because
I can't bring forth a noun to continue. Then after perhaps 2 or 3 seconds it
comes and I finish the sentence. Short-term memory getting worse also,
although in truth this has always been a weakness of mine. Still able to
function at work though, so that's a blessing.

My hearing is getting really bad also.

With me it's early morning. I get up around 3:30 to 4:00 AM most days.

Spend a lot of time perusing old analog meters etc on eBay. Added several to
my collection lately, including an AVO 8 which I got interested in after
finding you had one. It's a Mark 5 Nato model, on it's way from Germany as
we speak. Not many AVO's in the U.S. it turns out...

Added several Simpsons (the American answer to AVO?) lately as well. The guy
at simpson260.com has offered to sell me his 9 remaining Simpsons. I don't
think I can do that though, nowhere to put them!

Yeah, I know that Mark. Dunno. The older I get, the more this nonsense
seems to just fly out of my mouth (fingers)... Perhaps I'm going down
with some kind of early addle-brain. There's a prog on the telly next week
about poor old Terry Pratchett. He first noticed something was wrong,
when he kept typing spelleen misstaykes :-( I think that my problem
is that I spend too much late-night time sitting in front of this idiot
machine,
instead of getting some sleep...

There's nothing wrong with you. As you get older, you're more likely to drop
words or letters from your posts. And as time seems to pass faster, you have
less time and inclination to think carefully about what you've written.

Spend a lot of time perusing old analog meters etc on eBay. Added
several to my collection lately, including an AVO 8 which I got
interested in after finding you had one. It's a Mark 5 Nato model, on
it's way from Germany as we speak. Not many AVO's in the U.S. it turns
out...

Those large AVOs were to be found pretty well everywhere even vaguely
connected with electronics in the UK. Still available new up until
recently - at about $1000.
My original one got stolen many years ago - and like many others I just
used a DVM instead. But always wanted another - and got a perfect
condition one off Ebay a few years ago. Nothing else quite matches the
tactile switches. ;-) And of course if working to old service sheets,
voltage measurements were near always made on one so allowed for the
loading.
