Now that the DVD-R and the CD-R have been differentiated, it will be easier for you to choose which one you will be using for your projects and other file-saving activities. Have fun creating your very own music videos and mini-movies. Start saving today! DVD-R can carry 4 gigabytes up to 4. This is equivalent to 73 to 99 minutes of sound recorded.
Difference Between Similar Terms and Objects. MLA 8 Magno, Eva. Name required. The "music" and "data" CD-Rs are nearly identical with one very important difference. If you are using a stand alone CD recorder that is intended for copying music it will only function if you use the "music" blanks. These consumer machines check for a flag on the disc telling them that it is ok to record on the media. Part of the extra price of the "music" CD-Rs go to the record companies to compensate them for lost revenues.
Burners that are built into computers don't look for the flag. My knowledge of cd-r vs cd-r audio is exactly the same as mrlowry's. I do not believe there is any more difference other than that. Your comment regarding stand alone recorders is essentially true.
I had a stand alone Philips unit that was very fussy about which discs it would accept for recording. Most often the offending disc would record but then not finalize which wasted your time and money.
I never tried them but from what I read on the internet this deck had no problems with re-writable discs. But the cost of RW's was usually higher than most "Audio" labelled discs, which led you to simply buy the "Audio" labelled discs. I am also curious to know if the stand-alone units writes "disk-at-once" or "session-at-once". Depending on the situation, then maybe those special audio CDRs just have some sort of special blank session open on them or something like that I'm not sure why I'm so curious about this.
I've successfully burned audio cds using my old HP 8x2x32 burner, using them as both audio and data cds. It may be a different scenario now, though, since this was over a year ago.
They also have a code stamped into the CD header area where things like CD size are held. The set top recorder checks for this, and won't burn without it. It's real simple, just don't buy the audio CDs, they are worthless! I only use Kodak Gold and or Silver disks burned by Plextors and they play in everything.
Use the saved cash to buy an extra spindle of "data" cd-r's. Thus buying these discs is helping to support evil evil evil.
The special quality these have is the ability to be recorded in standalone CD recorders ie home stereo gear, made by Philips etc.
Don't waste your money on Audio discs. I was under the impression that "audio CDRs" use a better kind of dye than the ultra-cheap "data CDRs", as you are all well aware I'm sure, the cheap CDRs you get get at places like Fry's suck real bad for regular music. There is definately a difference, because data CDs simply won't work in stand-alone CD recorders.
It's kind of like when you buy Porsche--you get the leather seats "free. They aren't too bad, I wouldn't buy them again but they work just fine in my Lite-on 24x. It doesn't say anywhere what they are rated at but I have been burning them at 12x alright.
Not true. Audio CD-Rs are as useless as tits on a bull! They can play a data disc burned with audio from a PC no problem. My roommate used to work for Maxell and all we had in the house were Audio discs because that's what he got for free I've burned 's of AUDIO cdr's on my PC will no more coasters than usual. Because of this COnsumer Grade Standalone players will not recognize the disc as useable to burn.
Galaga is correct. I meant to note that audio blanks are completely unnecessary if you're recording from a computer, but I had to retype my post and forgot that bit. In order to ensure that they can play in all CD devices music CDs are thinner and lighter. What is a "printable CD-R"? What is a "re-writable CD-RW"? Which CD case or holder is best?
That's the list. Now here are the details A CD-R is a blank "compact disc - recordable". They were never recorded. Instead they were mechanically stamped or pressed, like the old-fashioned vinyl LP albums. Store-bought pre-recorded CD-ROMs use tiny pits or holes arranged in the tracks of the disc to encode the music, video or game software that you play. In a similar way, your CD-R burner uses laser-light bursts during your recording sessions to create tiny bubbles in the tracks around the CD-R.
The burner's laser blinks rapidly on and off, heating tiny areas of the bottom of the disc which expand into bubbles that closely resemble the stamped pits of a CD-ROM. A few CD players may have difficulty reading CD-R discs, but playback problems are usually caused by scratches, poorly applied or too-heavy off-center CD labels, and discs that have been exposed to heat or UV light -- discussed below.
You have probably heard of several types of CD-ROM discs, including those that contain music, software, video, photos, and games. CD players are made to be able to read or decode each of these CD-ROM formats so you can easily use the disc, without knowing much about its contents. CD creation software lets you select the final format of the disc you're creating. After you make a few optional decisions, the actual recording of a CD-R is usually quite simple.
See the manual for your CD creation software for more details. Once fully recorded or burned, a CD-R disc cannot be erased and used over. Therefore CD-Rs are sometimes called "write-once" discs. There are also erasable "re-writable CD-RW" discs. CD-RW discs are sometimes called "write-many-times" discs, and can be fully erased and re-written up to 1, times.
They are for data storage and editing uses in computers. We discuss CD-RWs in detail under question 12 below. Go to TOP 2 What do disc "write speeds" mean? CD-R discs are described by their recording capacity or runtime length. You can buy both minute and minute CD-R discs. Today most CD-Rs are sold in minute lengths, but you will see some brands that offer both 74 and 80 minute sizes.
The actual cost of making the discs is about the same. However, some of the very old CD burners do not recognize the minute CD-Rs, so the short minute discs are still offered by some makers. Both of the discs are the same physical dimensions or measurements - mm 12cm in outside diameter, with a 21mm center hole.
CD-Rs are also described by their write-speed certification. CD-Rs are tested and certified by their factories to be properly recordable at the rated speed.
Today's fastest write-speeds are usually 48X, but 52X rated discs are also available. The most popular write speed purchased in today's market is the 48X rated CD-R Today's fastest rated discs can burn at up to 52x speeds on 52x capable writers. In order to burn at a given speed, your CD burner, your computer and your software must be able to work at that speed, as a total CD recording system.
Whether or not you actually are able to achieve those speeds depend on many factors: The disc must be rated at that speed. Your computer needs to be able to handle data that fast through its connections, cables, motherboard and hard disc. Your CPU needs to be fast enough to do the work of translating the music or other signals you're recording into the encoding used to store the data onto the disc, and the CD creation software you're using needs to be able to handle the given speed.
Each part of your system needs to be able to do its part of the job. Today's mhz or faster CPUs, with fast hard drives and also with state-of-the-art internal motherboard hardware, are capable of easily handling any 32X or faster CD-R creation task. However, experienced users often choose to record their discs at a much slower speed.
This gives their system an extra "cushion" to avoid many burning errors that sometimes occur at the faster speeds. Since each different software, hardware and CD-R disc brand or type delivers a slightly different speed and recording-quality capability, a little experimentation will help you decide which speed to use. If you change your hardware, software, burner or other system components, or if you begin using a new type of CD-R disc, it's time to do a bit of experimentation again.
We want to publicly thank Bill for that technical reminder. That was the speed needed to PLAY a music CD in "real time", so you could hear the music as fast as it was actually being read, decoded into sound, and processed through your sound system.
However, the fact that 1X drive speed related to a 1-to-1 runtime for the disc is certainly NOT a coincidence. So, when it comes to burning, if you burn a disc at 2X speed, it takes half the runtime of your recording to get it down onto a disc, and if you're doing it at 4X, then it takes one fourth the time, and so on.
Basicly, faster X-ratings for discs mean that we can burn your discs at a proportional fraction of the disc's runtime. Remember, we're focusing here ONLY about burn time for discs, not about the basic data transfer rating of drives, or other theoretical considerations.
However, whether experienced users and experts like Mr. You may have noticed that most other blank CD-R discs have a colored bottom surface, usually a shade of light blue or green on the bottom. On the top, most CD-Rs usually have a blank shiny silver surface.
TruSilvers don't even have a slight hint of color on the bottom. They're completely colorless to the eye, so all you see from the bottom is the bright shiny silver top-reflector, just like a store-bought music or software CD. The TruSilver Diamond's colorless bottom layer contains special plastic material that absorbs laser light almost as well as the older light green or light blue materials used on other discs. And, once recorded by your burner, the disc will play in CD-ROM players just like your music or software CDs you bought in a music stores.
Of course they also work fine for storing data or software. PROs: They look much more attractive to most people and help you make a slick, professional impression on your customers, clients and friends. The colorless TruSilver bottoms are available with a wide range of top surfaces and colors, including inkjet printable surfaces and a wide variety of bright solid colored tops. See them at Even though new 40X write speed TruSilver CD-Rs are now entering the market, most TruSilvers generally burn at a slightly slower speed than the very fastest light green or blue bottomed discs.
When CD-R discs were first invented about 20 years ago, they were made with expensive gold reflector layers over a dark blue bottom layer that was super sensitive to laser light.
They needed this super sensitivity so that the slow computers, weakly powered lasers and unsophisticated logic circuitry in the drives and computers could produce a playable CD disc.
These dark-blue bottomed discs had a major flaw You had to protect your discs in dark, cool storage all the time.
