Disc composition

Digital Versatile Discs (DVD)
DVD video, DVD-R or DVD-RW discs are recorded in units called
"titles," with each title being divided into one or more sub-divi-
sions called "chapters." Further, some, discs are furnished with
menus for navigating the disc, but menus may not be included
with all titles. In the case of commercial films, a single movie
normally corresponds to a single title. On so-called "karaoke"
discs, each song track composes a single title, although there
are some exceptions to this rule, so care is needed when using
search functions.

Compact Discs (CD)
In the case of compact discs, each disc is divided into units of
individual tracks (normally, each song is contained on a single
track). In addition, tracks may have sub-divisions called index
numbers.

Handling discs

I When holding discs, do not touch their signal surfaces. Hold
by the edges, or by one edge and the center hole.
I Do not affix gummed labels or tape to the disc surface. Also,
do not scratch or damage the label.
I Discs rotate at high speeds inside the player. Do not use dam-
aged, cracked or warped discs.
I Do not play a disc with a special shape
¶ Do not play a disc having other shape than a circular disc, such
as heart shaped disc. Otherwise malfunction may occur.
I Storing discs
¶ Discs are made of the same kinds of plastic used for conven-
tional analog audio records. Be careful not to allow discs to warp.
Always store discs in their cases vertically, avoiding locations
with high heat, humidity, or extremely low temperatures. Avoid
leaving discs in cars; the interior of a car in direct sunlight can
become extremely hot.
¶ Always read and abide by the precautionary notes listed on
disc labels.
I Cleaning discs
¶ Always keep your discs clean by wiping them gently with a
soft cloth from the inner edge toward the outer edge.
¶ When cleaning discs, the use of a commercial CD/DVD clean-
ing kit is recommended.
¶ If a disc becomes very dirty, dampen a soft cloth with water,
(be sure to wring it out well) and wipe the away dirt gently.
Remove any water drops with another soft, dry cloth.
¶ Do not use record cleaning sprays or anti-static agents on discs.
Never clean discs with benzene, thinner, or other volatile sol-
vents or damage to the disc surface may result.
