Hey! CD Burners out there... should I use 700MB or 650MB CDR's?

[R2D2]

I need the disks to be compatible with all CD-ROM drives.

 

[blurredvisionx]

either size is compatiable with the same drives....use whichever you want

 

[brassmonkey7]

i've used just about all kinds....don't use CD-RWs though

 

[Quickfingerz]

I use TDK 650's for guaranteed relaibility and compatibility.

 

[Dan]

Either size is fine.

 

[Rand]

The size won't have any affect on compatibility.

If you do go with 700MB cdr's make sure that the software you are using will let you burn 700mb or it really won't matter.

question about cdr.
I burned some cdr of music for the car, but my car won't read them. They work fine in my computer, home stereo, even boom box but not the car CD player. Anyone with a guess as to why? Someone said I need to burn them at 1x speed. That's painful and I'm not sure I understand the reasoning.

HELP

TIA

The reflected signal recieved from a CDR is less than a CD, a CDRW is less again.

Burning at any speed will not help, you can try different media(dye color) but you may just need to get a car CD player capable of reading the weaker signals.

Whats a 650MB CD-R? 😛 All I use is 700MB now.....been using them for a long time with no problems what so ever.

I've found a very old CD-ROM drive, I think it's 2x that won't read to the end of a 700 MB CD-R - it makes worrying crunching and clicking noises when it tries.

I've also noted several stories about software companies distributing products on CD-R. They have all had many more returns due to 'incompatability' with 700 MB discs than 650 MB. The consensus from these companies is that Mitsui Silver SG 74 minutes are the best, with no returns.

 

[Gunbuster]

Incompatability mostly comes from "EA" type insane copy protection.

 

[freeflap]

thanks for the reply. I've seen "music" cdr's for sale. Are these actually any better or is it simply a marketing ploy?

Try burning at 2x speed. I had a problem with reading burned music CDs (by CD players not associated with a computer), then I read in a forum that music is easier read (via these other players) when burned at 2x. I tried it and it solved my problem. Good Luck.

The ONLY difference between 'audio use' CD-Rs and 'general use' CD-Rs, apart from the price, is what type of recorder is allowed to use them.

Audio CD-Rs are allowed to work on 'audio CD recorders' - these are typically standalone hi-fi recorders, that can be directly connected to a home audio system. These recorders are required to reject any blank that is not authorised for audio use.

Computer-based CD-R(W) drives can usually record on any disc, regardless of authorisation.

The allowable use flag is part of the ATIP code which is recorded as a 'wobble' in the spiral pre-groove which is stamped into the disc during manufacture - this means that it is impossible to change a 'general use' disc into an 'audio use' disc, and that as audio players cannot read the ATIP, there is no difference in readability.

As for recording speed - you need to experiment to find the optimum speed for your recorder and media combination; slower is not necessarily better.

Playing either size of cdr is not a problem in cd reading units, like cars or portables.

THey only thing you have to make sure is that recordign software and cd-recorder are able to record 80min/700meg cd's.

Hey, thanks for all the info. My burner should arrive tomorrow.

I had just read that some CD-ROMs might have problems reading the outermost tracks (between 650 and 700MB), not that I plan on recording that much Data.

Thanks,
