OT: about cheap DVD+R DLs
Hi,

> never knew they existed.
The actual info source is the search engine (Google in my case).
The CD rumor pages are of mixed usefuleness. Always check twice.
> How do you get from:
> RITEK/D01 To RITEK...D01?
Each program and each rumor page has own ways to produce an ID string
from the MMC media type data. Those MMC data vary from media type to media
type and often consist of more than one text component.
The text components have to be glued together to a single id text.
Thus we produce slightly different results.
I assume "RITEK...D01" is composed from "RITEK\0\0\0" and "D01"
out of reply fields of MMC command READ DISC STRUCTURE.
> Mounted Media: 10h, DVD-ROM
> Media ID: TYG11
The drive reports DVD-ROM but obviously it cannot be a real DVD-ROM
because those have no media id. This often happens when the media is
closed.
TYG is Taiyo Yuden Co. Ltd.
Google finds me
TY(TaiyoYuden) MIJ DVD-R DL 8x "TYG11"
"TYG11" seems to be the content of the first id component of DVD-R.
The second component is obviously empty.
(ECMA-279 describes a third component which seems to be used for
other purposes meanwhile.)
In dvd+rw-mediainfo 7.1 i only see "Media ID:" lines which print both
components, empty or not. So i wonder why it does not report
Media ID: TYG11/
DVD-R DL is incapable of multi-session. This explains why it is closed
now. On other drives it might appear as closed DVD-R DL rather than
as DVD-ROM.
Have a nice day :)
