CD-ROM Technology
CDs are now the main medium for distribution of software. ... Even with compression technology, this can amount to 15 or more disks. On the other hand, a single CD can hold about 650 MB of data and it costs less then a dollar to make. ...
CD-ROM drives come in many styles. ... The speed is denoted in terms of how much faster it is than a standard audio CD player. Therefore a 2X drive is twice the speed of your stereos CD player, and so on. Technology has advanced quite a bit. ... CD-ROM drives come in IDE, SCSI, or other proprietary interfaces, such as that of Creatives original multimedia kit. ...
CD-ROM drives are included in just about every PC on the market today. They are pretty simple at the end-user level, but there is a lot more to know about CD-ROM drives than most users care to know. ...
CD-ROM Media
CDs have become more broadly used than floppy diskettes. ... Stamping can be done quite fast, and CD printers have complex machines that can product many CDs at the same time. But, stamping is not the only thing that does into creating a usable CD-ROM. ... Next, a protective lacquer is coated onto the disc that will protect the reflective coating and help protect the CD from scratching. Finally, a label is printed onto the top side of the CD. ... "Pits" refer to the tiny holes that are burned into the CD using a laser. ... The drive uses a highly focuses laser light to read data off of the CD. The laser is directed at the data side of the CD. ...
Data is recorded to a CD disc as one solid spiral of data around the CD. ... Instead, a CD is separated into minutes, and a typical CD can hold up to 79 minutes. ...
CD-ROM Standards
During the development of the CD-ROM format, the standards have evolved into what we have now today - a very standard interface in which all CD-ROM manufacturer use the same standard. ... The resulting, agreed-on standard was named the High Sierra format, and this dictated the structure of files on a CD. ... All current CD-ROMs used the ISO 9660 format, and this means that software can be written to use all CD-ROM drives without special needs.
Some of the different standards for CD-ROM technology are bound in different color booklets, with all documentation. They are:
· Red Book - the standard dictating the CD Audio standard. ...
· Yellow Book - the standard which defines CD-ROM technology, the use of CDs for computer data.
