Description
In computing and optical disc recording technologies, an optical
disc is a flat, usually circular disc which encodes binary data
(bits) in the form of pits (binary value of 0 or off, due to lack
of reflection when read) and lands (binary value of 1 or on, due to
a reflection when read) on a special material (often
aluminium[citation needed]) on one of its flat surfaces. The
encoding material sits atop a thicker substrate (usually
polycarbonate) which makes up the bulk of the disc and forms a dust
defocusing layer. The encoding pattern follows a continuous, spiral
path covering the entire disc surface and extending from the
innermost track to the outermost track. The data is stored on the
disc with a laser or stamping machine, and can be accessed when the
data path is illuminated with a laser diode in an optical disc
drive which spins the disc at speeds of about 200 to 4000 RPM or
more, depending on the drive type, disc format, and the distance of
the read head from the center of the disc (inner tracks are read at
a faster disc speed). The pits or bumps distort the reflected laser
light, hence most optical discs (except the black discs of the
original PlayStation video game console) characteristically have an
iridescent appearance created by the grooves of the reflective
layer. The reverse side of an optical disc usually has a printed
label, generally made of paper but sometimes printed or stamped
onto the disc itself. This side of the disc contains the actual
data and is typically coated with a transparent material, usually
lacquer. Unlike the 3½-inch floppy disk, most optical discs do not
have an integrated protective casing and are therefore susceptible
to data transfer problems due to scratches, fingerprints, and other
environmental problems.
