58 Everything You Ever Wanted to Know About DVD<br />

Metallica: Cunning Stunts, and Sarah McLachlan: Mirrorball. Some movies,<br />

such as Detroit Rock City, Ghostbusters Special Edition, Mallrats, Suicide<br />

Kings, Terminator 2 Special Edition, and Tomorrow Never Dies Special Edition<br />

use multiple angles in supplements. Some discs, especially those from<br />

Buena Vista, use the angle feature to show credits in the selected language<br />

(usually with the angle button locked out).<br />

You can get an incomplete list of multiangle discs by doing an extended<br />

search at DVD File or a power search at DVD Express. To weed out the<br />

adult titles at DVD Express, select all entries in the category list (click top<br />

entry and Shift-click bottom entry) and then deselect Adult (Ctrl-click).<br />

Is It Okay to Put Labels or Magnetic Strips on DVDs?<br />

Labels and adhesive strips are dangerous because they can unbalance the<br />

disc and cause errors, or even damage a player, especially if they peel off<br />

while the disc is spinning. Pressure-sensitive adhesives break down over<br />

time, so it’s possible for labels to come loose after a few years. Libraries<br />

and DVD rental outlets often want to label discs or attach magnetic strips<br />

for security, but it’s best not to use them at all. If you must, use a ringshaped<br />

“donut” label that goes around the center of the disc. As long as the<br />

circular label doesn’t interfere with the player clamping onto the hub, it<br />

should be okay. If you have to use a noncircular sticker, place it as close to<br />

the center as possible to minimize any unbalancing. Placing a second<br />

sticker straight across from the center will also help.<br />

Writing with a marker in the clear (not reflective) area at the hub is better<br />

than using a sticker, although not much room to write is provided. Write only<br />

in the area inside a 44-millimeter diameter. Writing anywhere else on the<br />

disc is risky, because the ink could possibly eat away the protective coating<br />

and damage the data layer underneath.<br />

In most cases, a better alternative for security is a case that can only be<br />

opened with special equipment at the register or checkout counter. Barcodes,<br />

stickers, and security strips can be placed on the case without<br />

endangering discs (or players). This is especially good for double-sided<br />

discs, which have no space for stickers.<br />

Full-size round labels designed to go on recordable CDs and DVDs can<br />

be used, but they have been known to cause problems. As DVD-ROM<br />

drives get faster and faster, destabilization of the disc by a label may cause<br />

read errors. A better (but more expensive) solution is to use an inkjet disc<br />

printer (IMT, Odixion, Primera, Rimage, or Trace Affex) with printablesurface<br />

discs.
