CD-ROM
Short for Compact Disc-Read Only Memory, CD-ROM drives are CD players inside computers that can have speeds in the range from 1x and beyond, and have the capability of playing audio CDs and computer data CDs. Below is a picture of the front and back of a standard CD-ROM drive.Below are the different interfaces that allow a CD-ROM and other disc drives to connect to the computer.
CD-ROM transfer speeds
Below is the standard transfer rates and access times of the majority of CD-ROM drives. The below figures are averages you can expect to find on each speed of CD-ROM drive. These averages may be slower or faster than your CD-ROM drive and to where the CD-ROM is accessing the data from the CD-ROM. In general the higher this number is the faster the transfer rate or in the case of a disc burner the faster the write rate.
IDE
Short for Integrated Drive Electronics or IBM Disc Electronics, IDE is more commonly known standard interface for IBM compatible hard drives. IDE is different from the Small Computer Systems Interface and Enhanced Small Device Interface (ESDI) because its controllers are on each drive, meaning the drive can connect directly to the motherboard or controller. IDE and its updated successor, Enhanced IDE (EIDE), are the most common drive interfaces found in IBM compatible computers today. Below is a picture of the actual IDE connector on the back of a hard disk drive, a picture of what an IDE cable looks like, and the IDE channels it connects to on the motherboard.CD-ROM drives
Most software today ships on CD-ROM because CD-ROMs hold much more information than the standard floppy disk and are cheaper to manufacture. Software will never ship on Zip disks or LS120 disks because the media is too expensive and CD-ROMs are really cheap to make. Another use of a CD-ROM drive is to play music CDs on your computer or extract audio data to your PC.

CyberLink Corp. today released PowerDVD 11, the latest version of the award-winning media playback software for PCs. A universal player, is designed to be the only application you’ll need to view Blu-ray and DVD movies, videos, photos and listen to music.
PowerDVD 11 introduces a multitude of new features including support for playback and transfer of content from the iPhone, , iPod Touch and Android phones and slates to PC. In addition to smart device content, PowerDVD also facilitates the playback of remote media from sources such as DLNA servers and social networking sites like Facebook, Flickr and YouTube.
“While the PC remains central to the digital entertainment experience, portable devices and online content are playing increasingly important roles,” said Alice H. Chang, CEO of CyberLink. “PowerDVD 11 smoothes the flow between the PC, smart devices and online content so that users can get the most out of their digital entertainment anywhere.”
Media playback wouldn’t be complete without top quality audio, and PowerDVD 11 takes this to the next level with a premium 5.1-channel DTS audio experience across all three retail versions, as well as new Dolby Digital Plus support for MP4 files.
Samsung Electronics Co., Ltd., a worldwide leader in digital consumer electronics and information technology, today announced the internal DVD writer with fast Lead-In that considerably reduces disc recognition time during start-up. With SAMSUNG’s new DVD writers, consumers will get ultra quick load times, dramatically reducing the wait time from disc insert to usage in the Optical Disc Drives (ODDs).
DVD-ROM drives
DVD-ROM is a newer standard than CD-ROM, able to read 7 times as much data off of a typical DVD disk (4.7 GB) as opposed to the measly 650MB a CD-ROM drive can read, and also able to play DVD movies with the proper decoding software or hardware. With fast video cards and processors today, you typically don’t need any special DVD decoding hardware to play DVD movies. Microsoft ships a software DVD movie player with Windows XP that works fine.
DVD-ROM drives can read CD-ROM disks, so if you have a DVD-ROM drive, you don’t need an extra CD-ROM drive. Also, the x-factor for DVD drives refers to a higher transfer rate: 1x DVD-ROM drives transfer data at the rate of a 9x CD-ROM drive (150 KBytes/sec * 9 = 1.35 MBytes/second). Thus, a 5x DVD-ROM drive reads DVD data as fast as a 45x CD-ROM drive reads CD data. Most complete systems with DVD-ROM drives will ship with 12x or 16x DVD-ROM drives today. A slower drive isn’t out of the question, but with 16x and soon 20x drives available for cheap, why bother? DVD-ROM drives are dirt cheap today, so don’t even bother with plain CD-ROM drives unless you have no choice.
CD-RW drives
Remember, DVD-ROM and CD-ROM drives are read-only; that is, you can’t copy or save files to them. If you want to write CD’s, you will want to step up to a CD-RW drive for about an extra US$20. CD-RW drives can read regular CD’s and can write 650 MB of data to CD-R media (aka “greenies” – and some allow storage of 700 or 800 MB) that cost under US$1 apiece. CD-RW drives will also re-write data to CD-RW media which is slightly more expensive.
CD-R and CD-RW media can be read by standard CD-ROM drives after it is written. Also, you can use CD-R and CD-RW media in most consumer CD players, allowing you to mix your own CDs, or even to encode a CD-R full of MP3 files for play on newer consumer CD players (check to see if your CD player supports this). It’s great for long periods of music playback. We highly recommend a CD-RW drive for the functionality.
CD-RW drives are rated in three different speed categories. The speeds are listed as something like “40x/10x/4-x” and the speeds stand for: CD-ROM read spead / CD-RW write speed / CD-R write speed. Stick with at least a 40/10/40 drive if you can. Older drives write to media more slowly. If you go with those, you’re getting old technology.
A weaker option that is now nothing more than a curiosity nowadays is the plain CD-R drive. This type of drive is like the CD-RW without the “W”. Thus, it can write to CD-R media, but it cannot rewrite to CD-RW media. The cost of CD-RW drives is very reasonable, so we don’t recommend CD-R anymore, and you probably won’t see it as a selection anywhere, but is listed here for reference.
Recommendations
As you can see, you have many, many options. Nowadays, CD-RW is a necessity for the home user for making music CDs and backing up data on very cheap media. We recommend a combination DVD+RW/+R/CD-RW drive. This drive is being sold by Dell, if not others, and combines many different standards into one drive, allowing you to read CD-ROMs, DVD-ROMs and write to CD-R, CD-RW, DVD+R and DVD+RW.
Another option is the DVD-RAM/-R/CD-RW drive being pushed by Gateway and others. The DVD-R part is compatible with all of those Apple SuperDrives and the media they use. If you’ve got friends or family with Macs, you may want to go this route
Corporate client PC recommendations
There are not a lot of corporate uses for DVD+RW and CD-RW drives. Not only that, but they make it really easy for your users to walk out of the office carrying a lot of corporate data. You could stick with the cheaper standard old CD-ROM drives or look toward the future and go with DVD-ROM drives that now cost about the same price. Microsoft is starting to ship software on DVD, and more companies will follow. Do you want to have to deal with the marketing department saying to you, “Hey, can you get access to this clip-art DVD? My CD-ROM drive won’t read it!” It’s up to you.
Either way you choose, you should definitely have some sort of drive that can at least read a CD-ROM as that can make it easier to repair machines if you are not doing network installs. If users need DVD+RW or CD-RW for certain reasons, consider it in special cases, at least for your IT department for utility reasons. Also, you may want to give them to trusted individuals that are technically savvy that need to deliver data to clients or archive files locally. Remember, though, this is a security risk to have the capability for users to write 4.7 GB of corporate data off of your network onto a DVD+RW disk. Take proper precautions if necessary for your environment
DVD-R/RW / DVD+RW/+R / DVD-RAM
There are 3 competing DVD writeable standards: DVD-RAM, DVD-R/RW and DVD+RW/+R. DVD-R drives (aka “SuperDrives”) are shipping now in Apple Macintoshes, but Apple used used to ship DVD-RAM drives. Now, Sony, Philips, HP and Dell are backing DVD+RW. The DVD-R drive is somewhat more compatible with consumer DVD players, but DVD+RW drives have a larger group of companies backing them. If you own a DVD player and want to make DVDs of home movies to play in that player, you will need to research and find out whether DVDs produced by your DVD+RW or DVD-R drive will play in that player.
