Optical disk drives are also known as cd roms for your computer. They allow you to store data and burn information on them from the disk drive slot on your computer.
We can burn a disk when it is an re-writable disk even though it has data in it.But when it is an ordinary disk i.e., if it is an only writable disk with data in it,we cannot burn the disk with another data.
an optical disk which stores data optically
use a laser to read and write data. Optical disks have very large storage capacity but they are not fast as hard disks. There are three basic types of optical disks: CD-ROM, WORM and erasable. DVD-ROM is higher- capacity disc
optical disk storage are read only so they cannot get infected. But if you burn files which are infected by viruses then the optical disks can spread the virus
(a)- it is a read-only storage medium. Data once recorded, cannot be erased, and hence the optical disk cannot be reused. (b)- thd data access speed for optical disk is slower than magnetic disks; (c)- optical disk require a more complicated drive mechanism that magnetic disk.
Buy an optical external disk drive.
you burn the data
Yes, optical disks use a laser beam to read and write data on the disk. The laser beam is focused onto the surface of the disk to detect and interpret the patterns of pits and lands that represent the data stored on the disk.
Applications where re-writeable optical laser disk would be preferred over hard disks for storage are: While storing the data in large amount, the optical disk are more preferred as, for storing the videos, photographs and various types of the images. This optical laser disk are used for transferring the information or data from one computer to another so we can easily modify or re-write the data at any time as, this disk are more convenient than hard disk. The optical laser disk are also helpful for distributing the software to the customers or users by using its large storing capacity features, as compared to hard disks.
No. A disk drive can use one of several methods of storing data, including magnetic, Flash, and optical.
The optical disk was invented in 1958 by David Paul Gregg. He created a system called the Laser Optical Storage System (LOSS) that used a laser beam to record data onto a transparent disc.
