Any thoughts? Hopefully CD-R isn't the last advance in storage
technology, but what to do while waiting for the cavalry to arrive? And
what was all that stuff about "blue laser"?
Its kinda about what my experience is over the past 12+ years of using them,
some of the higher quality ones are still good, the higher quality kodak
ones are great but seem to have a max read speed of about 4x, the cost per
cd was 3x or more (I don't recall exact price for sure, but seem to think
hival's were $120+ for a 100pk and the kodak's were like that for a 25 pack)
most of the lower quality ones are not. IME I dont see the problems refered
to in the article, the article seems to leave off that most newer cd's and
most/all dvd readers can adjust to variences fairly well, and the error
routines do a great job. Instead I see issues with the coating, I see the
newer CD's and DVD's as a fix, a 2 part plastic layer, which protects the
recording surface. But being new, means who knows? older 1 part cd's would
flake but you still can read the media 1 more time, especially when using a
newer high quality drive programed for a real low read speed, if the newer
ones pull apart its possible all the data will be gone forever.
kinda depends on how you define archival, the article even points to hard
drives. if the hard drive is for archival it shouldnt be used frequently,
putting ball bearings kinda as a lame excuse to suggest the use of something
else. Additionally many/most failures Ive seen over many years do not point
to mechanical issues, instead some other failure. I also do not like his
pointing to tape, Ive had many more problems with older tapes than I have
with older CDs' and hard drives that were stored.
somewhere on the net, is an article about one of the musiums stopping the
use of CD's as an archival medium just for this reason, I tried searching
but have not found it in a short period of time, it was a major one though.
But what do I know I don't work for IBM :D
Instead I do data recovery, backup and archival on a regular basis, and
continue to do the CD thing which I started many years ago with recorders
that were so slow it seemed like I could type faster :D there are some
things that for survival sake need more than 1 copy, on more than 1 type of
media.
but thats just my opinion
