A few drives used to have a small fan mounted at back, guess laser diode and
supply run a bit toasty.

It's all heat related.

50-60mW power at 780 nM (near infrared) (depending upon CD-R vs CD-RW)

under normal use, heats to between 200-700 degrees celsius (also
depending upon CD-R or CD-RW).

Thermal dissipation through the CD, with insufficient dissipation out of
the drive itself, and the cd material (polycarbonate) melts at what
temperature?

 

[Torrance Bell]

50-60 mW is a big ass amount of power, compared to normal read lasers,
or even laser pointers which go up to 5mw.

50mw laser from a DVD recorder:

Blu-Ray is incompatible with DVD.
HD-DVD, however, is fully backwards compatible with DVD.

The studios are backing Blu-Ray, while Microsoft is backing HD-DVD.

This is leading to a very big format war like VHS and Betamax, but the victor
over all this chaos is probably going to be regular DVD since it has gained
such huge and widespread acceptance by consumers and the industry as a whole.

DVD is technologically obsolete, but it's like the CD: still way too useful
with too many benefits and having such widespread acceptance with a strong
foothold that it's not likely to be replaced anytime soon. This is regardless
of what comes to try and replace it, unless its superiority is as huge as "VHS
versus DVD" to the consumer.

MiniDisc couldn't replace CD, DVD Audio isn't replacing CD, and SACD isn't
replacing CD. To the minds of the consumer, the CD is more than good enough in
almost every imaginable aspect that replacing it with something that isn't
immediately noticeable as superior isn't justified. So, what makes the
industry think that consumers will leap over to Blu-Ray or HD-DVD with wide
open arms and wide open wallets as many people seem to be perfectly happy with
DVD Video in a manner very much like CD?

Besides, consumers don't like spending more money on this. - Reinhart

Sorry, but I lost the original post; set was a RH8546, I believe; this is the
set with the double-sided convergence board (located behind the front panel);
notorious for bad solder connection on the feed-thru's. You MUST solder every
one of them, both front and back, paying particular attention to the ones
closest to the large heat sinks. Expect it to take an hour or more, as there
are lots of them, and they're easy to miss...

Besides, consumers don't like spending more money on this. - Reinhart

The iPods, et al, are selling like hotcakes. They are stealing the show,
giving the CD format a run for its money bigtime. Apparently, loads of
consumers have deemed the little mp3 players to be immediately noticeable as
superior, at least in one very important way: convenience. Who wants to
haul around a bunch of CD's when they can hold their entire collection in
the palm of their hand, w/o having to swap media a single time to get
instant access to any track?

Some may argue that those same people probably kept their CD collections at
home. Talk to iPod users. You'll find many of them ditched most of their
CD's to make room for something else once they ported them over to their
computers and/or iPods. Space-saving and convenience features are very
attractive selling points. Most people nowadays don't seem to care much
about CD playback on a stand-alone unit attached to a receiver/amp. It's
the mp3 age, and most of these folks use their hard drives and/or iPods to
house their music collection. And no, they aren't all college kids.

Some may argue that mp3 only retains about 90% of the original CD
information. It doesn't seem to matter, except perhaps to the minority --
professional audio engineers or musicians, or those who like to think they
have a "golden ear". But then, the golden ear types also tend to argue the
superiority of tube amps and vinyl for everyday listening purposes.

At any rate, convenience is an important enough issue that it's helping
defeat CD's in the minds of a huge number of consumers, a number which is
steadily increasing.
Some people with CD collections may hang onto them a while longer, but sales
of new CD's are steadily declining. But that's in no small way due to the
increasing availability of single-track purchases online.

Greatly enhanced video quality and storage capacity of Blu-ray (or whatever
becomes the standard) will give DVD a run for its money, too. I don't know
anyone who wouldn't love to be able to cram 10 times the amount of data on a
Blu-ray disc vs. a DVD disc. More, smaller, faster, better. You all know
you've upgraded your hardware over the years, and not just because Mr. Gates
said you had to.
Obviously, years after Blu-ray, something else will come along to render it
obsolete as well. Such is progress..

Hell, I remember reading at least 8 years ago about some lab work involving
such media as holographic cubes (shades of HAL 9000) and animal protein
molecules. And they worked! Ahh, the holy grail of mass storage -- no
mechanical parts. Last I heard, they were getting down to the 55
terabyte/cm2 level way back then! Too bad it takes so damn long to bring
THAT kind of stuff to market.

So, what does all this have to do with the business of repair? For one
thing, it means more reliable products are out there and on the way, which
equals fewer jobs on your service benches.

Sure, there will be a few hardcore magneto-philes out there, but not enough
to keep you profitable, especially when the only place they can obtain tape
is thru obscure mail order providers -- as has happened with Beta. Even
Wal-Mart has seen fit to cease stocking high grade TDK, which I used to buy
in abundance, and has seriously reduced its inventory of blanks in general.
My last visit to Target revealed they are stocking NO high grade VHS tapes
whatsoever, when a few short years ago they had numerous brands. Noticed
the VHS sections of your favorite video rental store shrinking, too?

Sure, even the new Blu-ray devices will need minor repairs occasionally.
That may help you stay in biz, good luck.
Plasma's tendency to prematurely die may help you stay in biz. But I
believe plasma is just a momentary trend, destined to die out after the
awestricken masses eager to keep up with (or ahead of) the Jones' realize
that plasma's "super thin, hang-on-the-wall HDTV" superiority is
overshadowed by its pitfalls.

The real enemy to servicers will be such displays as OLED -- low current,
lightweight, inexpensive and highly reliable. Yes, I'm aware of the current
probs getting OLED into a larger screen area, it was just an example of
next-gen display tech which will kill plasma. The increasingly
uncooperative attitude of manufacturers won't be a lot of help, either.

I speak not of the immediate future. But I also don't mean 50 years from
now. Servicers who intend to do this kind of work for another 15-20 years
should be worried. Of course, the more who go out of biz, the less
competition in your neighborhood, so that may help you a little.. for a
while.

It would be nice for HDD backups, but as it stands now, almost all of the
non-backup CDs I burn end up with 5-50MB on them, so unless the Blu-ray
recorder also burns relatively cheap CDRs, I'll still need my CDR drive.

Has anyone started a betting pool on how long it will take the Windows
install disc to expand to fill a double-layer Blu-ray disc?

Of course, it would be nice to take all the various driver and software
installers for all the hardware on this computer, along with the OS
installer and all the patches for everything, and burn them all to a single
disc, but that won't be a nice enough feature to offset any cost over $200
for the drive. As it stands, I can probably stuff it all on a DVDR if I
pare it down to get rid of the product demos, the copy of Acrobat Reader
that darn near everything include, and other stuff I don't need...and get a
DVD burner.
