Should CDs and DVDs be stored at a specific temperature?
Discs used frequently should be stored at a temperature similar to that of the environment in which they are to be used. This minimizes stress from frequent temperature changes. Given the absence to date of relevant testing, the precise effects of storing CDs and DVDs in freezing temperatures are not yet known.
What is the best temperature for a CD player?
As I know, the good temperature for almost all things is between 0-40 Celsius. Ofcourse extreme temperatures will harm your cd. When the temperature increased the plastic the cd is made from will lose its shape and that will lead to the degradation of the magnetic layer that the data is stored
Do extreme temperatures harm your CD's?
Ofcourse extreme temperatures will harm your cd. It is the cold weather outside that makes your CD's skip. This is what happens if you leave the CD's outside in your car in extreme temperature regardless if the weather is extremely hot or extremely cold. Cold and heat are equally harmful to CD's.
How do you store a CD in the Cold?
Well, CDs storage instructions are to store them in a cool dry place. If it is too hot, the thin film where the data is kept may just seperate from the plastic disc, thus damaging it. I do not know about extreme cold though. Cos where I am, there is no such whether.
Can CDs be stored in a hot garage?
Electronics, Old VHS Tapes, Old DVDs/CDs, etc. Electronics and anything having to do with them should not be stored in a place where heat and humidity are not controlled. Changes in temperature and moisture can cause electronics to stop working, data to be lost, and pieces to become warped beyond use.
Can CDs be damaged by heat?
HEAT (yes HEAT Will damage CD/DVD media)3. Moisture*CD/DVD media is like a sandwich, 2 clear, plastic disks, recordable layer, and adhesive adjoining them.
Can CDs be stored in cold?
Freezing and thawing may create harmful stresses in the disc because of differing expansion rates of the layers, but it is unclear how much this stress might affect the disc. There may even be a benefit to uninterrupted freezing of a disc for an extended period.
At what temperature do CDs melt?
Polycarbonate, the plastic in CDs, is stable between ~ -40˚F to 280˚F. The acrylic layer on top has a similar stable temperature range. Since temperature inside of a car is within this range, there's no real possibility of deforming the disc.
How do you store CDs long term?
Store CDs in dark storage. Ultraviolet light, including sunlight, can cause the polycarbonate substrate or the scratch-resistant layer to darken, leading to player misreading and mistracking. Store CDs in an air-conditioned space because polycarbonate substrates can absorb moisture and react to heat.
Where do you store CDs in your car?
For the Car: My best friend in high school kept all of her CDs in a binder or two stashed somewhere on the car floor. Don't be like my friend. If you need a CD organization system for the car, stick to those handy folios that attach to your window visor, easily within reach.
Can you leave CDs in your car?
If stored in in a hot car, CDs can warp and jewel cases can melt together. There go your road trip tunes!
Do CDs lose quality over time?
Well-cared-for CDs can last many decades — even centuries. But storing a disc in a hot car or playing it often can eventually lead to "CD rot." "By increasing the relative humidity and temperature, you're increasing the rate of chemical reaction occurring," she says.
Why are old CDs considered hazardous?
Over time, CDs can release Bisphenol A (BPA), which can cause health implications in humans. Burning CDs releases toxic fumes into the air we breathe, and they require a special recycling process that isn't accepted in single-stream recycling bins.
Why are my CDs so hot?
As Bruce points out, they are not particularly flammable and would need to get extraordinarily hot to catch fire, and will in fact melt before they burn (which will cause them to jam your drive). However, it is odd that your CDs get so warm as to raise concern. The friction of the air against the surface should not cause them to warm up much, and the laser (regardless of the debatable points raised by others) is both weak and lights up only one tiny point at a time, so the only explanation for the discs getting this warm is that other components in the drive/PC are getting even hotter and some of the dispersed heat is warming up the CD. So personally, I'd be more worried about the drive than about the CDs.
Why does my DVD drive get hot?
Sorry, but the laser will not cause the dvd/cd drive to get hot. It is no different than a laser pointer; it will not get hot. Air friction from the disc spinning produces a little heat, but most of the heat is from the moving parts of the drive spinning very fast and bad air circulation within the drive. The poor air circulation is the worst part of the cd/dvd drive for computers as it traps the heat.
Can a hard drive get hot?
The answer is, don't worry. If you were foolish enough to load a severely distorted or a very heavily damaged or dirty disk, or maybe if the computer was in a factory getting all kinds of abrasive dirt into the drive, I guess things could get hot but you'd notice other problems (like it not playing your movie!) long before the heat was an issue.
Can you burn an optical disc in a fire?
With normal use, an optical disc should never come close to reaching the temperatures required to start a fire. You pretty much need to toss it in a fire, put it on a stove, etc in order to do it. Most players will only get the temp barely over 100 degrees F which is not even close to what is required to cause it to burn.
Do lasers put off heat?
lasers do put off heat which is the final form of any type of energy. The lasers used in optical media is so low power, the amount of heat it puts off is insignificant unless there are some problems? When the temperature increase the plastic the cd is made from will lose its shape will lead to the degradation of the magnetic layer that the data is stored
Why should a disc be stored at a low temperature?
If stored at a very low temperature relative to the user environment, the disc should be gradually acclimated to the environment in which it will be used to reduce stress and moisture condensation. A significant, abrupt temperature change will cause greater stress than a gradual change. Leaving the disc in its packaging will allow gradual acclimation to a changed environment. Discs used frequently should be stored at a temperature similar to that of the environment in which they are to be used. This minimizes stress from frequent temperature changes.
Why do you label a CD?
Marking and labeling a CD or DVD is an essential process in its creation. CDs and DVDs, or their containers, are labeled in some form or fashion so that they can be identified and organized. When labeling a CD with markers, the composition of the ink in the marker and the style or design of the marker should be considered.
How does light affect ROM discs?
Effect of Light on ROM Discs#N#Although the effect of light on ROM discs over time is not known, the effects of long-term exposure to light (e.g., UV, infrared, fluorescent) under ambient intensity, such as room lighting, are generally thought to be so minimal that light is not considered a factor in the lifetime of the ROM disc. Any effect of light on the disc would involve degradation of the polycarbonate substrate (plastic) and would become noticeable only after several decades of exposure to daily storage facility lighting or sunlight through windows. Degradation effects would likely be in the form of “clouding” or “coloring” of the polycarbonate. To our knowledge, there is no report on the potential impact of this kind of material change on the playability of the disc. Light effects on ROM discs, therefore, are considered negligible.
What is the error code for scratches on a CD?
These uncorrectable errors are called E32 in the Red Book for CD specifications, and PO Error in DVD specifications.
How long do RW discs last?
RW discs: RW discs, unlike the other types, can “wear-out.” CD-RW and DVD-RW discs should last for about 1,000 rewrites, and DVD-RAM discs, 100,000 times, before the rewriting capability is lost. The reading functionality of the disc should continue for a limited number of read times after each writing. While the maximum number of read times possible after writing is unknown, it may become fewer after each successive writing.
Why is it bad to peel a DVD label off?
DVDs are different; peeling a label off a DVD would not have the same adverse affect because the metal layer is not near the surface. Still, removing a label, or any portion thereof, from the surface of a disc can cause an imbalance in the spin of the disc in the disc drive, making the disc unreadable.
What causes a disc to be damaged?
The increased temperature generated by sunlight will accelerate the degradation or breakdown of the dye layer (recording layer) of the disc. The combination of high temperature and high relative humidity will further accelerate that degradation.
How to store CDs?
Well, CDs storage instructions are to store them in a cool dry place. If it is too hot, the thin film where the data is kept may just seperate from the plastic disc, thus damaging it. I do not know about extreme cold though. Cos where I am, there is no such whether. So cannot comment on it. If you really treasure your discs, it is better to keep them at home. Burn a copy of it on CDRs and play those instead. In the even the copies get damaged, you can always create new copies again to play them in your car.
Why does my CD stick to the packaging?
Sudden changes in temperature may cause condensation on the disc, this can cause it to stick to the packaging. Basically, extreme temperatures can make them warp. CD's are more vulnerable to bright light than other formats. The silver layer within the disc will decay, rendering the disc useless.
What happens to silver discs?
The silver layer within the disc will decay, rendering the disc useless. The most likely visible damage will be the small holes when you hold the disc up in the light. In extreme cases, the whole silver layer will flake away from the disc. The damage caused by light is irreversible... keep 'em in the dark!
Does temperature inside a car matter?
truely temperature inside the car only matters irrespective of outside ......temperatures.so i hope may be due to snow thats is entering during kmaki the parts get struck.thats all there is not much chemistry.......
Is it safe to keep CDs at room temperature?
I do not know which is more harmful...but it is recommended to keep them at room temperature. I have never had anything happen to my cds, so i do not know the effects of extreme temperatures..in less you count knowing what will happen if you microwave a cd counts.
Can a CD cover get damaged?
ok but if you place your cd into an extremely hot condition you can able to understand that that cover on that cd will getting damage..that golden cover on that cd will get some another color..but in the case of cold condition it will not affect the cd that much..
Does temperature affect CD?
Ofcourse extreme temperatures will harm your cd. When the temperature increased the plastic the cd is made from will lose its shape and that will lead to the degradation of the magnetic layer that the data is stored
What temperature does a CD deteriorate?
The CD plastic is poly-carbonate, and it stable in the -40˚F to 280˚F range.
Can you archive 80's discs in low humidity?
80's discs that suffered from bit rot from degradation of the reflective layer would probably fare better if archived in a low humidity, low temperature location. Also you don't want mold or mildew on your discs or inserts. Even glass camera lenses have been affected by mold growth.
How long do CDs last?
Well-cared-for CDs can last many decades — even centuries. But storing a disc in a hot car or playing it often can eventually lead to "CD rot.". Well-cared-for CDs can last many decades — even centuries. But storing a disc in a hot car or playing it often can eventually lead to "CD rot.".
Why is it so hard to preserve CDs?
And here's the thing about CDs: Youket says part of what makes it hard to preserve CDs is that they are not uniform. There were a lot of different standards of manufacturing, depending on the year and the factory.
How many CDs does the Library of Congress have?
But "there is no average, because there is no average disc.". The Library of Congress has around 400,000 CDs in its collections, ranging from congressional records to popular music, and the library regularly gets donations of CDs.
What is it called when you leave a CD exposed?
This is a variant of what's called "CD rot," Youket explains. In this case. it's what's called "bronzing." The outer coating of the CD erodes, leaving a silver layer exposed. And when you leave silver exposed, it tarnishes.
When did real estate records move to CD?
Real estate records and titles were also moved from microfilm to CD beginning in the 1990s all around the country, says Jim Harper, president of the Property Records Industry Association.
When did the compact disc become popular?
Back in the 1990s, historical societies, museums and symphonies across the country began transferring all kinds of information onto what was thought to be a very durable medium: the compact disc.
Do CDs come with drives?
Increasingly, CDs aren't being created at all. The record shops that sold them are going out of business, and new computers don't come with CD drives any more. Even so, many of us still have dozens or hundreds of CDs.
How to store discs from convection heat?
If there is something you are really concerned about, try a sealed container with a desiccant in it, make back-up copies, and test your copies periodically for read errors so you can make new copies when the old start to fail.
How long does a DVD last at 20C?
2 - The only threshold temperature is where the CD burns/melts. The rest is a increasing rate of decline as temperature increases that follows an exponential curve doubling for roughly every 10 C increase in temperature. If a DVD will last 30 years at 20 C, the same DVD can be expected to last about 15 years at 30C and so on. This is based on standard statistical aging curves. (Note that many components are rated at 85C; garden variety electrolytic caps for example, are often rated to last 1000 hours at 85 C, which mans that only a specified small percentage will fail by the time that exposure is reached. 1000 hours at 85C becomes something like 15 years at 20C.)
Can you heat a DVD?
Well, yeah, that's not ideal. You just have to risk it, I guess. Note that heat won't really affect pressed DVD ( no dye), just burned ones (dye). The magnetism won't make any difference; discs are not magnetic storage, they're optical.
