Short Lifetimes of Optical Drives?

lpq asks: "I have various optical disc readers from standard DVD players (apart from a computer), and both CD and DVD readers on one or more computers. My home stereo DVD's have been problematic for a while. One of them won't even take a DVD cleaner disk as it doesn't 'recognize' it as a playable disc, even though it plays discs that my other DVD player won't play. Usually, between the two of them, I can play most discs, but occasionally some discs, purchased new, won't play on either of them. Heaven forbid if it is an older or used DVD which have even more problems (some of my DVDs are approaching old age at an age of around 5 years). However, this is more about my computer's optical drives, including the CD readers. Both CD readers on two different computers have 'died' and are not able to read program disks. Am I specifically plagued by bad luck or do others go through CD/DVD drives so quickly?" "My built-in DVD reader (Dell laptop) no longer reads DVD's, but can still read CD's. My external SCSI plextor has a hard time with music CD's, but can still read most program CD's. My iomega external won't recognize program CD's but can still seem to do DAE on audio CD's.

My internal DVD/CD drive in my desktop can't read either DVD's or CD's. It was about 3 years old. The iomega external was about 2 years old. The laptop internal DVD was about 3-4 years old.

I took apart the IOMEGA, thinking it the easiest to get apart and took an air blower to the lens, but looking at it under a magnifying glass, I can't see a thing wrong with it. It still won't load any program disks, and kicks them back out as unreadable.

One computer is in my bedroom, the other in my living room with both commercial DVD players being in the living room (one used to be in bedroom, but with reliability issues of the older one in the living room, I moved the one in the bedroom out to living room. I still have to switch cables frequently depending on the DVD, as most play on the Digitron, the Sony seems to have poorer error recovery.

Is there anything I can do for maintenance. Air-canisters seem fairly limited in effectiveness and I've verified, at least in the IOMEGA external USB, it wasn't a scratched lens or at least nothing visible under magnification. This is really starting to drive me a bit crazy. It doesn't seem like I should have to replace these things so often.

My parents bought a new DVD player, and 2 out of 3 movies they tried to rent to play were unplayable. They are in their 70s-80s, so they just didn't want to bother with such unreliable technology.

It concerns me to hear about higher capacity DVD's, since with greater density, errors will affect wider areas on the disk. I'm always careful not to touch surfaces of CD's/DVD's but I don't know if the higher density DVD's will be very stable for movie or data storage if they don't do something to improve error recovery.

What do other people do for optical disk drive maintenance? Do other people have to replace them every 2-5 years because the drive is no longer cleanable?

As for video DVD's, should I just be resigned to play errors on almost 50% of DVD's -- usually they won't play on at least one of my players. What about bit-rot on the DVD's. Should I also be resigned to the fact that a DVD purchase is really only a temporary (5 +/-2 year rental) before it becomes unreadable?

The more egregious DVD problems have been with new, multi-CD series, where maybe one disk out of a 6-disk set (Buffy-season 2), Stargate Season 7, just won't play? It's a pain when they are gotten via mail-order even if they are a reputable dealer, since in both cases I've had 1 out of the set be bad, it was the last disc which I didn't get to for a few - several weeks.

What am I doing wrong?"

      Remember the original Playstation that had serious problems after a while? Problem there was that the little sled that the lens was on had a plastic runner. After X hours of seeking, it would wear down slightly, causing the lens to drop on one side. This is why turning the PSX upside down made a difference.

    I think the big problem with DVD players and drives is that the marketplace has dictated that they be a cheap, low-margin item. Consider: most DVD players don't even have RF outputs. Yeah, most people use component outputs, but RF is still widely used, and most VCRs and PVRs support it. Profit margins on DVD players must be really low for them to leave off a feature that's still pretty standard.

    So how else do manufacturers cut corners? By skimping on quality control, obviously. If 20% of your production run dies within months of coming off the line, it costs you -- but apparently not as much as making your production methods bulletproof.

    When my mother asked me to help her buy a DVD player, I knew she'd freak if she bought one that died quickly. So I looked hard for a model that has a solid reputation for never breaking down. Couldn't find a one. Even the expensive models from Big Name brands seem to get a lot of complaints that say, "Had it for a year, then it died." Thought of recommending a service contract, but that's almost as expensive as replacing the thing every other year. So I had her buy the cheapest one in sight, and crossed my fingers. So far so good.

    Perhaps you're doing something wrong, but I think you've probably just had a run of bad luck. The only thing you can do is just replace the drives as they die. There ought to be a better answer to your problem than that -- but I really don't think there is.

    Two short stories:

    A friend of mine had a portable CD player that he hooked through his home stereo with a Y-cable. He put the CD player on top of the amplifier when in use. Guess what happened? The heat from the ventilation slots on the amplifier ultimately killed the accuracy of the CD player such that it wouldn't track anymore.

    My parents bought a cheap DVD player and set it on top of their TV. They don't have a home theater or stereo system, so they just use the speakers built into the TV. Plus, my dad is losing his hearing so he always has to jack the sound way up on movie to hear the dialog. Guess what? The DVD player now doesn't track right, probably due to all the vibrations being constantly sent through it by the speakers inside the TV set.

    Laptop optical drives (and hard drives and screens and everything else) die frequently because people jostle their laptops around and mistreat them, so no surprise there. But if you're having as many optical drive tracking-related failures as you claim to be having, then your drives are probably getting damaged through thematic mistreatment. Make sure your drives aren't sitting on any surface that eminates heat or is carrying vibrations.

    BTW, the reason heat kills tracking of optical drives is that 99% of optical drives are built with a standard type of laser-tracking mechanism. The laser head rides along a metal rod/rail on one side, and then a parallel worm gear drives the head movement on the other side. With this approach, it's crucial that the metal rod/rail and the sleeve that rides on it have a low-friction relationship so they don't catch when the worm gear on the other side is trying to slide the head around. It's also crucial that the worm gear itself have a low-friction relationship with the threaded sleeve that rides along it so that it won't catch or bump as it does its work. It's typical for manufacturers to put some special lubricant on both the worm gear and the slider rod to reduce friction -- and it turns out to be essential for the whole thing to work. If you continually expose the device to heat, or to extremely dry conditions, the lubricant dries up and then the device won't track properly anymore. I've fixed several CD/CD-ROM drives that weren't tracking right by simply opening them up and applying a safe-for-plastics (silicone-based) lubricant to the worm gear and rail/rod with a Q-tip, and then working it in evenly by putting in a full audio CD and skipping from track to track to cause the head to move along the full range back and forth a few times.

    2) Make sure the case has positive air pressure inside (simplest way is to have one more intake fan, placed at least halfway up the case, than it does outflow fans), to keep air flowing OUT through the various drive orifices. I live in the dusty desert with house cats, and even so, thanks to their intake fans, my systems stay nearly white-glove clean inside.

    This was marked as flamebait, and it may well have been intended that way.

    However, the reason they're made in China is because China is dirt-cheap to manufacture in.

    They may well be capable of producing better quality drives, but that would require more quality testing (and so on) which is going to add to the price. And the consumer has shown that, everything else being equal, they will go for the cheaper drive.

    I don't know how China would stack up if quality were a bigger factor, because I don't know the level of skills required, how many people with the necessary skills live in China, and so on.

    In other words, would the cost of (increased) QA in Chinese-built goods be as proportionately cheap as the basic manufacturing cost in China?

    Would it be worthwhile training people, or do enough people with the necessary skills (at the right price) live in China? Or would it make more sense to manufacture elsewhere?

    Truth be told, I don't know; this is a can of worms. What I do know:-

    (1) China is very cheap to manufacture in, and
    (2) Long-term or even general quality/QA is far less important than the manufacturing (and hence retail) cost.

    As I said, if (2) changed, it's totally unclear whether China would be a good bet or not. I suspect it might still be, but with a far narrower margin of competitiveness to its rivals. But (2) hasn't changed; so the goods with the lowest QA are produced in the country with the lowest manufacturing cost. Doesn't mean they aren't capable of better, it means that the market would prefer "cheaper" to "better".

    Is to pay a lot of money for it.

    Dust and pollen, smoke (a really bad one!) do all shorten the life of a drive, but the REAL kicker is cheap-ass mechanisms. Anyone can buy a $1 laser diode and build an optical pickup, but these cheapo diodes are, well cheap crap. Just like LEDs (see earlier /. article from today) laser diodes dim over time, cheap diodes dim faster, and often have a lower voltage bias set because they can't handle as much power. The lower initial voltage makes them go out that much faster.

    Beyond the cheap diodes used in so many cheap electronics, the mechanism design itself is important. a good laser pickup will be SEALED. Many cheapo pickups have the internal guts of the pickup exposed to air, that means not only is the objective lens going to collect dust, but so is the prism, colimating lens, mirror and photo-diode face. Thats no fewer than 5 extra surfaces to collect dust, pollen and smoke (Did I mention that smoke is REALLY bad?) Spend about twice what the cheap ones cost and you'll get a unit that lasts twice as long.

    I have a Mitsubishi CD player that cost over $2500 in 1988, it STILL WORKS PERFECTLY! Not only that, but it reads CD-Rs just fine too! It sounds like crap 'cuz it's got first generation DACs, but the high quality laser diode and sealed mechanism have shown thier supperior resistence to the vageries of time. The 1x(!) CD drive for my SUN 3/110 (manf. date 1989!!!) also works perfectly, and that sucker probably went for almost $4000 new.

    Cleaning and re-alignment are both do-able and can correct the sorts of problems outlined here, but unless there's solid engineering and quality parts behind the lens it's not worth bothering.

    Another thing you get with a more expensive drive is better error correction, both HARDWARE and SOFTWARE. Many cheap drives have a set-screw for sled angle and tracking linearity, the best drives have self-adjusting mechanisms. Also, better drives will have wide-range variable power controllers for the laser instead of just a couple switched resistor pre-sets, this allows the drive to more accurately correct of the tranmissive and reflective changes in the surface of the disc. Even basic drives have pretty good "groove tracking" but being able to correct for optical variations is important too. Good error correction software is also important. A nice buffered oversampling drive should be ABLE to read through a pretty decent size scratch wihout issue. But drives with tinny buffers and poor re-read capability will choke on the smallest scuff.

    P.S. RE: celaning discs... Those little brushes don't pack enough force to alter alignment on most drives, unless they are cheap-crap or spin up to 52x. The lens itself is on a floating electromangenticaly aligned sub-frame, so it can get bashed arround by those brushes quite a lot without problems. The real issue with cleaning discs is that they just don't do a very good job. They are OK preventative maintenance, but once the lens gets dirty enough to start effecting the drive's ability to read discs, you'll probably need to go in there with an Alcohol dampened q-tip. Also, smoke residue (Did I mention this one is the worst?) is quite sticky and will not redily come off without a little alcohol.

    On some of the older drives, there were also trimmer-adjustments for various parameters in the support cicuitry that could become out of spec due to age and other factors, as well as being barely in-spec from the factory to start with. These trimmers (if they exist) should only be tweaked if you have the proper test equipment (*good* oscilloscope, DMM, frequency counter, signal generator at a minimum) and tech manuals with values and procedures specified, otherwise you'll have junk quickly.

    The bargain drives aren't really such a bargain, as the quality of components and initial alignment/adjustment and quality assurance are marginal at best. As has been the trend for some time now with most consumer electronics, it's easier and cheaper to just replace it rather than repair it.

    I noticed a few posts mentioning using compressed/canned air cleaning. This is about the best method, but use caution. The pressure of a compressed-air blast at close range to the optic head can damage it also. The actual optic lens assembly floats on extremely fragile, tiny springs, and is very easy to damage with a strong blast of air.

    Overall, the best ways to get maximum life out of your CD/DVD drives are to handle them like the fragile devices they are, don't use "cleaning discs", and by whatever method, try to keep dust/smoke/etc. away from the drives.
