Sharpies don't use ink, they deposit a thin layer of plastic. There's nothing left to "seep in" after they're dry.
I've done this for about ten years on cds. Believe me, it's safe.

If you're like me, sometimes you forget to label your CD-Rs, and after a while you end up with a big stack of discs and no idea what's on them.

I just number mine (since I can write it small in the middle), and then put the details on the case (instead of scribble I can't read). No problems so far. Mine are mostly music and backups (it would be a drag if those failed, but I'd live), not movies.

be careful with the fine point sharpies. never happened with DVD, but i have had a couple of CD's rendered unplayable by them. they have a firm tip and it can damage the layer beneath.

How hard are people pressing to 'scratch' the outside surface of a disk??
Are you telling me the data is RIGHT underneath a paper thin plastic coating? I thought the actual data is sandwiched in the middle??
Ive had scratched CDs play fine due to the refraction being against the grain, etc... are you saying that the BACK (top) of the CD is MORE fragile?

The writable surface of a CD is necessary to reflect the laser beam back to the reading head. A scratch on that surface takes away the reflectivity so it's actually much worse to scratch the top than it is the reading side.
I believe a DVDs reflective layer is deeper down in the disc.
