Problem is you need an M-Disc drive to read it for sure - what does that
mean? Well the disc is supposed to be compatible across all DVD readers BUT
I have found my older Lite-On IDE drives, which were considered very good
back in the day, have had problems reading the DVDs. So your mileage may
vary...
Thank you.
OK, that is alarming. The claim that the discs produced are fully
compatible is bogus. That was an essential requirement. Next aspect
would be whether they are completely incompatible with EVERYTHING other
than M-Disc, or just SOME types of drives, and if so, WHICH ones.
From what I've read, the difference in drive
between BDXL and BDXL M-Disc
is trivial enough that there is no reason that ALL
BDXL wouldn't go that
way, unless there are patent issues.
Also of note the original company has gone bankrupt
and their assets bought
out. The new owners are continuing to produce M-Disc media.
The drives are being made by LG, Pioneer, etc., so that part is OK.
The media is being manufactured by Verbatim, Memorex, ?
Does the demise of the original company, and hence the licenses, place the
ability of Verbatim, Memorex, etc. to make the media at risk?
(or only the legal rights to use the logo?)
Is the new owner more stable, and/or did Verbatim, Memorex, et al, at
least negotiate contract provisions for continuation of license after
demise of licensors?
Is anybody else doing any significant work towards long-life media?
We need ongoing supply, continuation of compatable hardware, and adequate
(non-"trade-secret") documentation - without Belafon, we've lost the
knowledge, and have to speculate, exactly what his hardware does.
