Disc Elements--eliminating
the misundertanding towards the disk.
Misunderstanding1:disk lifespan could be hundrs of
years an long as it is protected propeily.
Disk life span depending on three pactors.
(1)Disks itself is physical and chemical features. Disk consists
of polyplastic, a layer of alumium film. Too high or too low
surrounding tempreture can speed up plastic aged rate film comtacting
with air will age fradually, Further more, disk base are readably
only can not be rewritten. Damage can not be repaired and signed,
which are very different from the magnetic disk.
(2)Everyday protection.Disk is freguenilly used in mutll-media
eippication, In comect way of using and producting probably
shorten the lifespan of disk .Disk box , CD cleaner brush, disk
cleaner and disk drive provide us with convenience of using
and protecting.
(3)Replacing the old with new.The great development and changes
had happened in computer industing . Declination is approaching
when a kind of technigwe is at the peak. The most popular coftware
upgrated a new edition in the past years. But to us disheatedment,
The longer distance the disk driver transters the poorer sight
the disk is.
The readable disk in the past time can not be read now. It should
force the wares to lind a miracle that first put it into damaged
disk, then into the nomal disk, so it is an ideal situation
to expect the disk how hundreds of life span.It can be called
the got of longeoity when the disk lasts for 10 years.
Misunderstanding 2:The time the disks using in disk
dineve is too long, the more the time is ,the easier it can
break the disks that twist quickly, The disk head in the disk
drive sets off the laser and shots on the disks by reflection
light to inapect the data out by the changing of the reflection
light, In this process ,the disk head doesn’t touch directly
with disk, without breaking disks, It is the dirty and deformed
disks that will infwence the laser to focus and the fixed position
precision even break the disk head mecharicaly.
Misunderstanding 3: Plartic urface can be proteiled
well,which can ensure using disks normally. Many people all
know the fact that the laser prenaters from the plastin while
wring. The scrape finger print or dirt on the plastical aurface
may influenle rending data, but infact, data are stored in aluminium
film, The preserving coat is very thin, evena slight friction
may destroy it leading to fatal breaking to aluminium film .
However, the scrape in the plastic surface can bi conpenrated
by conrecting wrong data, Strictly speaking, aluminium film
layer and presering coat are more important than plastic, so
they read more careful preservation. By the way, Never label
on the preserving coat, Convencecince is temporary, when lable
loses sticking and sticks up , Aluminium film will be sticked
up. The chenrishable data in the disks will be taken away simutanilusly.
Misunderstanding 4: The disks out edge are the most
important area , so lots of information stored there , The way
of storing disks is different from software’s , the most important
part of software is the 0 and 1 magnetil way of its out edge,
while disks data are recorded with twist order from inside to
outside, The experienced people may know the scrape par to disks’
out edge may make several pictures not show normally, while
the scrape from in edge of the file form’s beginning or ending
may kill the whole disk.
Misunderstanding 5: The disks with dirt (if it will
not inflvence reading disk) can contincce using, If you find
some dirt on the disks you should use flannelette silk or dear
skin to clean. Otherwise, the dirt will stick to the disk head,
and inflvence reading data, You’d better pay attention to two
points while cleaning. First, you should make sure your action
is very slight, in case of bringing new scrape, you should clean
from inside to outside, along radial which will reduce the damage
to disks.
Misunderstanding 6: Dirt on the disks can be cleaned
by paper and alcohol. Paper is too hard to disks. The scrape
it brings is harder to clean than the stubben dirt. Alcohol
and other organic solvent and make plastic surface as a result
the laser cait focus, even more, it will permeate the plastic,
making aluminiun film parade in the air and aluminium film damage
takes place, which will damage the disk data completely, The
right way to clean stubben dirt is, clip the absorbent cotton
into the water (distillation is better), clean the dirt place
constantly along rodial. You also read slingtly doing it, oil
dirt can be cleaned with absorbert dipping into neutral cleaner,
the same way as above, then dry the disk with a dry absorbent
cotlor. At last, put it in the cool place and makes it dry.
Pay attention not to leaving water drops on it, otherwise decorative
pattern will turn up when it is dry. And don't put it under
sunlight for a long time in case of receiving heat and deforming.
