185.0. "Marking CDs?" by LEROUF::HEIN () Fri Sep 20 1985 15:15

Hi,

	Whatabout... labeling your disks, for two reasons:

	- because CDs are not very vulnerable I am quite willing
	  to borrow and/or lend CDs among friends. Although I do
	  trust my friends it wouldn't hurt the remind them that
	  a particular disk is mine!

	- I live in an area where crime rate is reputably high.
	  Although luckely no burglar visited my place yet, most
	  people convince me that this is unavoidable in the long
	  run. Thieves here, tend to have special interest in any
	  HiFi equipment, incuding records.

	The "operating" instructions of CDs explicitly recommend
	you not to use any marker on the disk. I can see how a
	stickup able would not be a good idea. (though perhaps
	a circular label, or a 'countre' label on the other side,
	could possibly avoid un-balance). I would think that some
	un-erasable marker pens are harmless.

	Experience anyone? Specific markers to use (or avoid)?

	I would avoid using anything. Remember that the pits are just below the label; adding a mark might cause problems reading the data if the pen solvent penetrates the lacquer at all. Steve

	Perhaps writing on the very inside of the disk might be ok. Thats where the manufacturer stamps numbers.

	..and you could do that on the "thick" side.

	What about labeling with a UV dye of the type laundrys sometimes use to identify clothes? The thief couldn't see it, but with a UV light, you could identify them as yours.

	re .4 It's probably of greater benefit to mark them so a thief can see the marks. That might discourage him from taking the disks, though I doubt it. Once the disks are gone, there's very little chance you'd ever see them again to shine lights on. Best choice is get apartment insurance and be prepared to file a claim.

	I've marked several of mine in the center where there aren't any data tracks using "permanent" markers. Definitely don't mark over or any where near the data tracks. /ralph-littleton,ma/

	...also remember that CDs play inside out. Unless the disk has a full 60-70 minutes of program, you could mark the OUTSIDE edge, over the unused tracks. You can usually see a difference in the mirroring once the data stops. Anything past that point should be safe.
185.8		NULL::KINMONTH	`Mon Oct 28 1985 20:16`	4
	I doubt that any thief is going to care if you mark them or not. For lending to friends, however, marking is not a bad idea. In this case it's enough just to mark the jewel box with your name. No need to fool with the disc....
