A compact disc is a type of optical disc. "Optical disc" is an umbrella term for any type of storage media which uses optical technology (as opposed to magnetic) for data storage. This includes but is not limited to DVDs, CDs, H-DVD, blu-ray, laser discs CDRW's, and DVDRW's
two types - magnetic in the form of magnetic tape,magnetic disc and optical in the form of compact disc.
No. Floppies are magnetic storage. Cd-rom, dvd, and laserdisc are examples of optical.
To read CD-ROM's, the technology in a CD-ROM drive is an optical disc drive (ODD). It typically utilizes light to retrieve information on a disc.
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".
A DVD is an optical storage device, hence the lens used to read the disc. It cannot be overwritten. A video cassette, on the other hand, is a magnetic storage device. It can be rerecorded over.
A magnetic disk - has a metal coating that stores the data by being written with a small magnet (similar to audio & video tape). An optical disk uses a laser to 'etch' the data onto the surface of a metal-coated glass disk (similar to a CD).
The optical disc was invented in the 1950's and 1960's. The first patents for this technology were registered to David Paul Gregg in 1961 and 1969. The Music Corporation of America bought the rights to these patents.
optical storage technology
If you burn infected files onto an optical disc then those files remain infected and would remain on the optical disc permanently.
The Compact Disc is a spin-off of Laserdisc technology. Sony first publicly demonstrated an optical digital audio disc in September 1976.
CD and DVD disks are used by optical disc drives.
A VCR (videocassette recorder) is an electromechanical device for recording and playing back full-motion audio-visual programming on cassettes containing magnetic tape whereas a DVD player is is an optical disc technology.

No tablet has an optical disc drive.
types of optical disc drive are: cd,dvd,blueray,cdr,cdrw,dvdrw,mp3,mp4
Compact Disc, an optical disc to store digital information
are smooth and leve areas on an optical disk
optical storage writes and retrieves data using a laser or similar. Magnetic storage uses a coating on a disc or tape to hold data, by manuplating the tiny ferrous elements on the surface it can store information. A CD is optical storage. It has a series of lands and pits (ups and downs) - as the laser passes over these it converts them into 1s and 0s.
An optical disc drive is primarily an input device. However, if it is writeable, it can be an output device for external storage.
DVD+R is a recordable optical disc. The first dual layer DVD+R that was created was in the year 2003. The disc was demonstrated that double layer technology could be used with a DVD+R disc to nearly double the capacity per disc.
Digital Versatile Disc or Digital Video Disc, is an optical disc storage media format, and was founded in 1995.
