Tips on Your DVD CareDVD's quickly exploded onto the market and people everywhere were scurrying to replace
their VHS tapes with DVDs. They do not come without their problems, though. The following
lists some tips for keeping your DVDs in good working order and describes some common
problems that you may find in your DVD collection.
These tips are designed to help you keep you DVDs in top condition. Following these tips will
not guarantee your DVDs will last forever, but will prevent them from becoming damaged
1. Don't put them in direct sunlight, or let them sit in hot rooms. Both of these will cause the
Mylar film that the data is written on to delaminate, hastening the aging process.
2. Don't scratch them. Much like CD-ROMs, scratches (and even dust) can render a
DVD-ROM unreadable. It's even worse for DVD-RWs, which "erase" data by filling in some
of the holes in the Mylar, and overwrite existing files by filling and reburning the patterns of
holes in the Mylar layer.
3. Make sure they're in their cases when not in use. This is the number one cause of DVD
failure, especially in houses with children, who tend to leave their DVDs out on the floor,
spill soda on them, and in general act as children do.
4. Make backups. If you've got a DVD-R, make backups of your most important DVDs -like
your children's favorite movie - so that the original can be kept in a climate controlled room
in the dark, to make more duplicates of when the children destroy the disk by squabbling.
5. Burn to DVD-R for archival purposes, and long term archival purposes, rather than
DVD-RW. Because the media that's written to is thicker, DVD-Rs tend to age better than
6. Back it up to a secondary hard drive that's kept off site.
Of course, to get the most out of your DVD-R drive, you'll need to keep the drive mechanism
cleaned up and well dusted, and buying higher quality (archival quality) media is something
to consider - though the formats themselves haven't been round long enough to know if the
archival media gives a significant edge in long term readability.
Common problems you may experience with your DVDs are related both to use and
manufacturing. The protective film on the underside of the DVD can bubble up or start to
peel away. This problem can be due to manufacturing issues or from heat, stacking the
DVD or rubbing against the surface. When this occurs the DVD becomes useless as the
player can not read it. Any scratches will immediately make the DVD useless. Another big
problem comes from bending the DVD. DVDs are made in layers and bending them can
cause these layers to separate.
Most people invest much time and money into their collection and by following these
simple tips you can avoid common problems that would make your DVD collection useless.
