A beam of light used to record and retrieve data on optical disks is known as __________________.
The correct option is A Polarized light
A beam of light used to record and retrieve data on
optical disks is known as laser.
Examples of this media are compact disk read-only
memory (CD-ROM), digital versatile disk read-only memory (DVD-ROM), digital
versatile disk random access memory (DVD-RAM), write-once read-many (WORM)
cartridges, erasable optical cartridges, and Removable Mass Storage (RMS) media
which are removable disk (RDX) and ...
Optical storage, electronic storage medium that
uses low-power laser beams to record and retrieve digital (binary) data. In
optical-storage technology, a laser beam encodes digital data onto an optical,
or laser, disk in the form of tiny pits arranged in concentric tracks on the
disk’s surface. A low-power laser scanner is used to “read” these pits, with
variations in the intensity of reflected light from the pits being converted
into electric signals. This technology is used in the compact disc, which
records sound; in the CD-ROM
