Optical Disk : What is it?
 Optical disks are removable devices used for storing and retrieving data. They consist of a recordable grooved film trapped between layers of polycarbonate plasctic. They are used for storing digital files such as documents, photos, music, and videos. They are read by compatible optical drives using laser beams, which analyze the grooves on the film and convert them into viewable data. Some discs can also be written and rewritten on using disc burners or recorders. |
Kinds of Optical Disks include the following:
CD-read only memory (CD-ROM) optical disks CD-ROM disks are permanently recorded with data that cannot be deleted or overwritten. Their examples include basic CDs for storing music, DVD-ROM for storing movies, and DVD-Video for storing digital videos. WORM optical disks WORM optical disks are blank, flat devices that look like floppy disks. They function like CD-ROM disks once data has been recorded. They are also called write-once, read many and micro-optical (MO) disks. Erasable optical disks Erasable optical disks allow users to write, delete, and overwrite data using CD-RW or DVD-RW drives. They are also called rewritable optical disks in CD and DVD format. |
| Capacity and compatibility: Choose optical disks with a large storage capacity if you store large amounts of data. However, larger capacities may not be compatible with standalone CD and DVD players. Standard discs with a capacity of 700 MB for CDs and 4.7 GB for DVDs usually have the highest compatibility. |
