Blu rays That Aren't Perfectly Round... - Blu-ray Forum

Sky_Captain · 05-29-2008, 02:24 PM

Apologies for the fairly vague thread title, but anyone else had BDs that aren't actually smooth around the edge, that look like they have various indentations all the way around?

The first disc I saw like this was Lionsgate's WAR, the disc looked like a saw blade in a certain light. It played ok, but I eventually sold it and bought the UK disc, which had no such problem. In fact, it's only ever been U.S. discs I seen with this issue. Is this a blatant production line issue?

I opened my copy of Face/Off that came a couple of days ago, and it has the same issue,(never mind the fact that it has the usual silly Paramount problem of the actual cover not being cut straight. Mine doesn't even fit the case properly. Asses.). I've never seen this problem with any other optical disc format, so just what the hell is it? My copy of The Terminator has a minor version of it, so even Sony has been affected at one point.

Just to clarify, I have NEVER seen this on a disc from outside of the U.S. be it France, Hong Kong, Japan or Australia. Seems a bit sloppy for such a high end product and I've now seen enough of this oddity to actually ask a question regarding it.
Thanks.

That's freaky. Never noticed it on any of my 135 BD's but then, I haven't actually looked for it. It might just be as simple as the actual disc manufacturing plant's way of making them. If there's no issues with playback, I wouldn't sweat it at all.

NOT ONLY BD has it, DVD has rough edges and its nothing big deal.

I have a pile of DVD-Rs that have bumpy edges. They work great. I wouldn't worry about it unless the player makes noise while playing it.

I've seen lots of DVDs that look like this too. CD-Rs and DVD-Rs, +Rs etc. I think it is the glue or something.

Prolly just a manufacture's issue. But I have seen them on BD and DVD and never had any trouble with it. I doubt it will cause any problems either.

The Lion King · 05-29-2008, 03:59 PM

Several DVDs I've either owned or played have this problem too. Can't say I've come across it on a BD, though.

Sky_Captain · 05-29-2008, 04:27 PM

Yeah, it is a wierd one. As long as the discs play, I was worried initially that it would throw the drive off, if the disc wasn't perfectly round.

It's actually a form of scratch protection. If the disc is ever put down somewhere, the actual disc surface doesn't come in contact with anything. Read more here.

I've only seen it on single layer 25 gigabytes BDs.
