Strategy Types

[Ejoc]

So I just tried out some new Philips CD-Rs, and I ran cdrdao on em to see their info, and they differ from all the other ones I've used:

Philips:

CD-RW                : no
Total Capacity       : 79:57:73 (359848 blocks, 702/807 MB)
CD-R medium          : CMC Magnetics Corporation
                       Short Strategy Type, e.g. Phthalocyanine
Recording Speed      : n/a
CD-R empty           : yes

PNY/Everything else:

CD-RW                : no
Total Capacity       : 79:57:74 (359849 blocks, 702/807 MB)
CD-R medium          : DIGITAL STORAGE TECHNOLOGY CO.,LTD
                       Long Strategy Type, e.g. Cyanine
Recording Speed      : n/a
CD-R empty           : yes

Besides being 1 block smaller, it uses a different strategy Type Phthalocyanine, does this make any difference? Has anyone experienced more/less coasters based on Phthalocyanine vs Cyanine.

Unfortunately, it seems that, although there are quite a few disk makers, there are only a few glass and nickle master makers.

They make the master die with all that data on them, and every reflective layer is stamped with it, but the small stampers use whatever dye they have on hand, or can get cheap, or whatever.

It's one reason so many brands all show the same information.

CDRDAO doesn't give ATIP? Try Nero Infotool, and you'll be even more flummoxed.

Cheers,

I can't speak for their RW's, but CMC manufactured CD-R's generally don't have a very good reputation. They have improved over the years, but I still can't get a good burn out of them at anything in excess of 8x - 6 if I want to read it back on my oldest, steam powered CD-ROM.

I have never had any go bad, but quite a few bad from the burn.

I havent watched the disc from start to finish, but I checked it out(watching different parts of the movie accross the disc) and it seems to be functioning just fine. This like all my others was burned at 24X

But the fact that the strategy type is different doesn't lead to more/less errors, it's usually other factors? Basicly I'd like to be able to pop a CD-R in and go "Hmm this one will probably give me trouble" or "Oh its got X this shouldnt have any problems."

Id just to be more knowledged about CD-R media.
