Blu Ray disks have a rot problem though that is becoming common on DVD's
I have 2 that have gone bad.

It doesn't look like traditional rot because the spots are all on the
plastic layer, even on the hub where there is no aluminum layer. Rot
(on laserdisc) was a failure in the aluminum, not the plastic.

p.s. Blu-Ray discs are harder to scratch because they have an anti-
scratch coating. This is needed because the data is recorded much
closer to the surface of the disc.


Which makes beta Ray more prone to damage and rot. A good scratch will kill
a Beta Ray whil a DVD will play just fine.

The Beta Ray movies I rent from BB are just as scratched the **** up as any
other disk. At least 1/2 I rent don't play.
Extra coating is good for kids I guess..still does not help much if at all.

nothing beats just plain old common sense. none of my DVD's/Games or
practically anything are scratched.

He's right. The data is very close to the top of the disk so they HAD to put
an extra coating on it. My kids wrecked 2 of my Blu discs. the scratch thing
marketing imo and just adds to the cost plus is of minimal help anyway. No
substitute for proper handling.

All this Next Gen stuff should be on cartridges or flash media ROMs or
something!

Has nothing to do with "rotting". The disks are not "prone" to rotting.

Rotting? Polycarbonate "rotting"? Never heard of this. There can be
damage due to UV exposure, though if this is a problem for a specific
device, there can be UV inhibitors used in the base polymer.

The disc itself should outlive the useful life of the technology.

Thats what they said about DVD and CD's and they are rotting all over the
place now.

Bitrot is another name for it. more common on burned Cd's DVD's but still
were not getting the "lifetime" of safe starage like they claimed. more like
6-15 years.

"Bit-rot", is not the same as "rot". The former implies usefulness of the
device that cannot be known until the device is placed in service, the
latter implies a physical condition that can be visualized.

I cannot say that I have seen this phenomenon of bit-rot myself, and I have
discs that are quite old that I still use, a few of them 15 years (I even
have some 5 1/4" floppies that work), though I wouldn't discount the
phenomenon.

2nd tier low cost vendors are very cost conscious, and may use other 2nd or
3rd tier vendors for the raw polymers to manufacture the media, as the resin
is the highest manufacturing cost. A few cents per pound can mean a much
higher gross margin when using millions of pounds, and could be a
contributing factor (I see this in other segments of the polymer industry
all the time).

disc rot is very rare and has everything to do with defective sealing
of the protective layer, I have about 50 LDs and about a thousand CDs
and DVDs, I have had exactly 1 disc rot in that time ( a poor pressing
of an eric burdon greatest hits.) I've had CD since 1983 and DVD since
inception.

Bottom line is that defects occur in anything manufactured, optical
media is much less likely to deteriorate over time than just about any
other media.

As far as burned CDs and DVDs, that's a different problem as the
technology relies on a dye, not physically pressed pits, the dyes are
subject to breakdown over time.
