with new data. To read a CD, you need a CD-ROM player. All CD-ROMs conform to a Known by its abbreviation, CD, a compact disc is a polycarbonate with one or more metal layers capable of storing digital information. The most prevalent types of compact discs are those used by the music industry to store digital recordings and CD-ROMs used to store computer data. Both of these types of compact disc are read-only, which means that once the data has been recorded onto them, they can only be read, or played. Another type of compact disc, called CD-Rs and CD_RWs, can have their data erased and overwritten by new data. Currently, erasable optical storage is too slow to be used as a computer's main storage facility, but as the speed improves and the cost comes down, optical storage devices are becoming a popular alternative to tape systems as a backup method

CD-ROMs are particularly well-suited to information that requires large storage capacity. This includes color large software applications, graphics, sound, and especially video .|SCSI CDROM CDRW Recordable Drives|

Here you will find basic info on CD-R Technology |SCSI CDROM CDRW Recordable Drives|

CDR Basics Are you considering purchasing a CD recorder or rewritable but are confused about the difference? CD recording technology changes quickly, and it's easy to get confused.A CD-Recorder (also called CD-R drive, CD burner or CD writer) can record (write, burn) to one blank CD-Recordable disk at a time. The disk can be used once only, although with the proper settings in supported software, you can add to the disk in more than one recording session until it is full. This is called "multisession" recording. The disk cannot be erased and used again, however. CD-Rewritable drives (CD-RW) make it possible to erase what you have previously recorded and re-record again over the top of it. How many times you can do this depends on the specifications of the disks being used. Some disks claim that you can erase and rewrite up to 1,000 times! However, you must use rewritable media (CD-RW) which is different than standard CD recording media (CD-R). |SCSI CDROM CDRW Recordable Drives|

Okay, so you purchase a burner, but before you worry about media, you have to hook it up. If you are using a Windows system with a Pentium processor and purchase an IDE-compatible recorder, you will probably connect it to your IDE (Intelligent Drive Electronics) interface which is the same interface to which your hard disk is connected. Most systems will have two interfaces and can therefore support two devices. There are some external CD writers that can be hooked up to your parallel port (normally used for printers). If you purchase one of these CD drives, see the manufacturer's instructions for installation. |SCSI CDROM CDRW Recordable Drives|

SCSI: The Standard for CDR/W Many high speed drives are SCSI-based. SCSI stands for Small Computers System Interface. To use these drives, you will need to install a SCSI adapter (also called a card) inside your computer. With a SCSI adapter you can also hook up other SCSI type devices like extra hard drives, scanners, Zip or Jaz drives. SCSI devices are usually faster than IDE devices.If you are using a Macintosh, hook your drive up to your external SCSI port (although some Power Macs and other models may support an internal drive - see your manufacturer). The iMac has a USB port - not a SCSI port. At the time of writing this, there are no CD recorders available with a USB port. One of the problems is that the sustained data transfer rate of the USB port on the iMac is not fast enough for a 4X recorder. This produces buffer underrun and results in "coasters" - CDs that are useless!Both CD-R and CD-RW disks will hold up to 650 Mb of data or 74 minutes of audio, although we now have CD-R disks that will hold up to 700+ Mb of data and 80 minutes of audio. The length of time it takes to record (write) a disk depends on how much data or how many minutes of audio you have and the speed of your CD recorder or rewritable. If, for example, you have a full 650 Mb of data or 74 minutes of audio, at single speed it would take 74 minutes to record. A 2X recorder (recording at double speed), it would take 37 minutes to record. If you have a 4X recorder (recording at quadruple speed), it would take 18.5 minutes. |SCSI CDROM CDRW Recordable Drives|

Some recording software (also called pre-mastering software) have a feature that allows you to verify the data you have written against your source file (disk from which you are recording), and that will take a little longer.
