Approximately how fast do disks, CDs DVDs etc. spin? Most CDs and DVDs use CLV (Constant Linear Velocity). The RPM changes so that the Data Transfer Rate can remain the same. DVDs spin at 1530 rpm when reading at the innermost (starting) edge, and slow down to 630 rpm when reading the outermost edge (end) CDs also start at the innermost edge.

What Happens When a CD Spins Too Fast? How Fast Was the CD Spinning? They break several CDs, but let me look at the second CD they shattered recorded at 61,960 frames per second. I tried to use the higher speed video, but I was getting repeating frames—not sure why. The guys claim the critical spin rate for a CD is 23,000 rpm.

Build Your Skills: A comparison between DVD and CD-ROM As you learned in my All About CD-R and CD-RW Daily Drill Down, CD-ROM data is stored in patterns of pitted and unpitted (“land”) areas on a disc. DVD data is stored the same way, except the pits are much smaller and closer together. That’s why CD-ROMs top out at about 650-700 MB of data, while DVDs can hold multiple gigabytes of data. Since the pits are more tightly written on a DVD disc, the mechanism in the drive for reading them also has to be finer and more precise.

Difference Between DVD-R and CD-R Difference Between DVD-R and CD-R. DVD-R and CD-R are two devices used to store data. While DVD-R stands for Digital Versatile Discs-Recordable, CD-R stands for Compact Disc-Recordable. The basic difference between the two lies in the amount of data they can store. While a CD is able to store only 700 MB data, a DVD-R can hold up to 4.7 GB of data.

Difference Between DVD-R and DVD-RW A spindle of 50 DVD-R costs same as a spindle of 15 DVD-RW which implies that DVD-RW are nearly three times the price of DVD-R. Difference between DVD-R and DVD-RW. • DVD-R and DVD-RW are two formats of digital video discs available in the market. Both allow the user to record and store media files. • However, DVD-R stands for readable DVD which means one cannot remove the information once stored on it.

Upgrading & Repairing PCs: Optical Storage Transfer speed is measured two ways. The one most commonly quoted with optical drives is the x speed, which is defined as a multiple of the particular standard base rate. For example, CD drives transfer at 153.6KBps according to the original standard. Drives that transfer twice that are 2x, 40 times that are 40x, and so on.

How DVDs Work Single-sided, single-layer DVDs can store about seven times more data than CDs. A large part of this increase comes from the pits and tracks being smaller on DVDs. 1  CD = 1600 nanometers. 2  DVD = 740 nanometers. 3  CD = 830 nanometers. 4  DVD = 400 nanometers. 5  CD = 830 nanometers.

Difference Between CD and DVD A standard CD can hold 700MB of data, around 80minutes of CD quality audio, or up to 60minutes of video. The later standard called the Digital Versatile Disc or DVD is still an optical media much like the CD but with much greater capacities, starting at 4.7GB at the low end to as high as 17GB.

Difference Between CDROM and DVD Difference Between CDROM and DVD. DVDs and CDROMs are both optical storage devices that have a lot of use; the most prominent of which is the distribution of content like movies, music, software, and such. The biggest difference between a CDROM and a DVD is their capacity. A CDROM typically holds 700MB of data per disc while a DVD can hold 4.7GB on a single layer. Dual layer and double-sided DVD discs push this to a maximum of 17GB. This is also the main reason why the CDROM was superseded by the DVD. Another advantage of a DVD is its much faster data transfer speeds.

Why It Do That?: Spinning A CD So Fast It Explodes A major difference between the high speed motor and the CD-ROM drive is that the drive has a means of balancing the CD whereas the motor does not - this adds extra external forces due to the imbalance. These forces can be in the form of harmonic vibrations which can cause the CD to explode.

Understanding CD Burner Speeds The last number (24 in the above example) indicates the speed at which the drive will read data from a compact disc. So in the above example, the CD drive will read data from a compact disc at 24 times 150 KB/second. CD-R compact discs are discs that can be recorded on only once.

How fast does a CD spin? It depends on which track you are listening to. Since CD's are read from the inside out, as disc spins significantly faster on the first few tracks, around 460 RPM (Rotations per minute). Towards the end of the disc, it doesn't have to spin as fast to read the same ammount of information, and would spin around 200 RPM. 12 people found this useful.

CD/DVD comparison chart +RW and-RW: Rewritable discs that can be burned multiple times (up to 1,000 times for DVDs), allowing you to continually add more data. +RW is superior in quality to-RW. DVD-RAM: An optical, high-speed, rewritable disc that can store video with or without using a DVD burner. It's more robust than a traditional DVD, better protects data integrity, and can be rerecorded up to 100,000 times. DVD-RAM comes in two versions: a specially coated disc or a disc cartridge.

What is the difference between DVD and CD.....? CDs are primarily for music. The difference between stamped dvds and cd's (the kind you buy as music cd's and video dvd's) is simply the baud pitch i.e. the physical dimensions of a single pit or peak and thus, owing to the identical surface areas, the potential storage capacity.

-ROM, -R, +R, +RW? Understanding the optical drive alphabet soup CD-: Compact Disc. These hold about 700MB of data. A CD drive can only read or write CDs. DVD-: Digital Video Disc or Digital Versatile Disc. They usually hold about 4.7GB. DVD drives can also handle CDs. BD-: Blu-ray Disc. This has to be the worst tech acronym since FLOPS. I mean, shouldn't there be an R in there somewhere? Fortunately, they're often called Blu-ray drives and discs. They usually hold 25GB. The drives are CD and DVD compatible. The acronym after the hyphen tells you what you can do with that type of disc or that type of drive. -ROM: Read

CD, DVD or SD: what's best for backups? The long-term reliability of optical discs is still unknown, so there are no certain answers. All my backups are on write-once CD-R discs, which I reckon is the best bet for data you want to last 10 or more years. Their main limitation is that a CD will only store about 700MB of data. That was fine when I started, but it is becoming less viable every year.

How Long Do CDs, DVDs, and Tapes Last? Its not uncommon to find a DVD player that can only read CDs because the DVD laser died and the CD laser is still going strong. Cheap DVD players typically only last 6-24 months, while the better-made units can go on for 5 or more years. The solution here is to try a better or newer player or drive.

What is the difference between a cd drive and dvd drive The oldest drives handle CDs but not DVDs. Newer drives that handle DVDs are almost always backward compatible and work with CDs as well. In addition to drives that read CDs and/or DVDs, there are drives that can burn (write data to) special blank CD and/or DVD discs.

How Many Minutes Are on a Blank CD? According to the Optical Storage Technology Association, the standard size for a CD is either 8 or 12 centimeters. The latter is much more popular with consumers because it can hold more data, typically 650 or 700 megabytes. These two sizes can store 74 minutes and 80 minutes respectively. On the other hand, an 8 centimeter CD has a size of 185 megabytes and can hold just 21 minutes of audio.
