From CD Freaks.com:

1.4 gb on a cd-r, that's nice and all, but unless a "normal" cd/dvdreader can make use of it (read the disc) it's of pretty limited use i think.... at least in the short term, untill all ppl have a hd-burn read capaple cd/dvd B)

It is possible due to the fact, that the pits have some kind of tolerance they must fit into; Hiqh Quality Audio Recording (or what was the name) from Yamaha was based on bigger pits (but still in tolerance) and this technology is based on smaller pits (but still in tolerance).

well, sounds like i'll be getting one of those hd-burn capable burners as my next cd-r/dvd recorder then ...

... i wonder if dvds have similat tolerance that can be exploited the same way

This has already been discussed last year: http://www.hydrogenaudio.org/forums/index....=ST&f=20&t=3620

There is no tolerance regarding speed in the official standard. Red book implies CLV from 1.2 to 1.4 m/s.
1.2 m/s gives 74 minutes per CD according to the old standard, extended to 80 min in a revision of Red or Orange book.
1.4 m/s (as used by Yamaha Audio Master) gives 63 and 69 minutes under the same conditions.

If this method goes below (at a given pit/land rate), it just works because the current technology physically allows it, as it allows to read audio at 30x while Red Book implies 1x.

I can't understand how it would stand the comparison with recordable DVD. Inferior capacity, inferior compatibility, weaker quality standard.

Market saturation with cheap blanks?

I think Plextor also announced a new drive that will burn 1GB to a CD.

And in related news, some people have taken to calling french fries "Freedom Fries."

With the price of DVD writers and media dropping, who wants to take a huge risk and burn excessive amounts of data to CD's?

It would be nice in a crunch and to play around with at least. This would probably not be the safest for long term, who knows, but anytime one can get more megabytes for their money its a good thing.

http://www.digital-sanyo.com/BURN-Proof/HD...BURN/index.html for more info. These discs can be read in DVD drives with modified firmware.

As stated in their FAQ, HD-Burn will only work for Data CDs not Audio CDs.

If this technology could catch on I think it would be really cool. CDRs are much cheaper than DVDRs and this would be cool to put DVD backups in XviD with better quality than just 700 MB CDs. It would also be nice to backup four Audio CDs with lossless files on one of these discs.

To me it seems the same problem you have with 99' CD's, since the TOC can not cope with larger capacities.

However if the drive supports reading HD-Burn, all the DVD-Players with such a PC drive should be able t read it (hopefully), same as with 99' CD.

But there are a more questions not asked here so far,why not smaller pit's = DVD-sized where used. The best collection of info & Questions I know so far is Sanyo introduces 1.4GB CD-R burner/DVD Burner @doom9.org

I just hope the drives will be available in EUR soon too.

A CD player can't read DVD sized pits. They are too small. A red laser is needed.

Yes, but DVD-drives should be able to read everything up to the size as small as DVD-pits and HD-Burn Pits are a bit larger then DVD-Pits

@ snn47 (& others) - HD-Burn probably does not use DVD-sized pits because the engineers at Sanyo probably found that they were too small to be used on CDRs. I'm sure that when designing this technology the engineers at Sanyo made numerous tests to find the smallest pit size that can be used on CDs while ensuring that they could still be reliably written and read by the majority of DVD players. Remember that there are physical differneces between DVDRs and CDRs that allow smaller pit lenths to be used on DVDRs (this is part of the reason why they are more expensive).

@ Pio2001 - Remember that HD-Burn uses CDRs it is only designed to be written and read by DVD players thus it will always be read by a red laser.

I din't know this, sorry
