Blank CDs over 80 minutes

Postby PrezCRG on Wed Jan 15, 2003 9:30 pm

I am trying to figure out the technological relevance of 90 minute and 99 minute blank CD-R discs. I don't know where to find them for sale, and once I do, I am skeptical that a CD player would even be able to read 99 minutes worth of music on such a disc. I just bought the Yamaha CRW-F1, among many other reasons/features, because it recognizes and records on the longer blank CD media. I know this can be helpful when employing Yamaha's Audio Master technology or in saving space for its DiscT@2 graphics on the backside of a disc. Where exactly does the current burner technology stand on these 90 and 99 minute CD-Rs, and how do you think they will integrate this longer blank media into their burner systems? Do many burners and/or their software even recognize any CDs over 80 minutes/700 mb yet?

I would certainly love to be able to make 99 minute music CDs or comparable data discs.

Thanks for your insight -- this subject has been bugging me for a while.

You can buy 99 min. CD-R's here:
http://www.yesbuy.net/9099mincdrsi.html


Apparently the site stopped selling 90 min. CD-R's. That is where I bought my 99 min. CD's and everything works great with them. I don't know about compatibility with the F1 or any set top CD Players.

I wouldn't use 90 and 99 min. CDRs unless it is absolutely necessary.

Christian:
Check your private messages. You've got 2 from me on this subject.

They are safe to use, regardless of what the creator of Fuerio did to screw his drive.

I remember reading that he killed a drive trying to push it to its limit by writing a 99 minute cd-r in a drive that clearly did not support it.

That is simply carelessness, unless he sacrificed it for our knowledge. Which he did. Learn from his 'mistake'. If the drive does not support the media, don't try and force it to. All it may need may be a firmware upgrade. Then it may never have been designed to handle the new discs either.

I'm not aware of the F1 supporting the 99 minute discs.

I checked here: http://www.yamaha.ca/computer/pdf/crwf1_2.pdf

but then it could be like LG and just not tell people about it.

Yamaha USA says it does support 99 minute discs!

The problem is not breaking a burner.
The problem is compatibility between those discs and readers. Those discs are out of specification... They are not real CDs.

So, if you're going to use those discs only for you and know that your players accept them, it's OK.
But don't expect that you lend them to someone and work without problems...

I'm more interested in compatibility than in extracting a few more minutes from a disc. In fact, I've never needed to use a 90min. disc.

1) Compatibility between systems- newer hardware can usually handle the data discs. Older cd drives ( & DVD drives) may have a problem with data discs.

99+ minute audio discs play fine in any music cd player that I've tested them in. Tom's hardware had the same results with their 2 tests on 99 minute discs.

Some computer drives still did not like the 100 minute audio discs, but that's more due to the time code problem, than playback ability. Discs with over 100 minutes have a screwed up display screen, but they still play in a music cd player, including my Sony Discman in my car.

Bottom Line: Sharing Data? Use a 74min or 80min disc. It's cheaper too.
Making a Data back up for yourself? They're fine. The extra 170mb can come in handy if you make DivX movies etc.

Making a huge audio disc? They're fine on all audio cd players and many computer drives, but may have trouble tracking on a computer on the outer part of the disc.

As for the 99 minute cd-r not being a 'real' cd. They are. Time will prove this.

3 years ago, 80 minute cd-r's were not a 'real' disc and my HP drive did not support them. HP's line was "if it's not in the Red Book, we don't support it". Now, TDK is making 90 minute cd-r's. On a side note, TDK were the 1st company to market 80 minute discs, even though they were not standardized (or real). My, how times have changed since my 2x2x24x HP 7570i.

If anyone's interested, there's a lot of information over @ www.cdrfaq.org on the history of cd drives and media.


FYI: I put my webpage back up for anyone who may be interested in a 100+ minute audio cd.
