yes it can, its only the speed of the data that gets burned onto the cd that changes, the physical structure of the data is always the same.

Another possibility is the "low-speed" CD-ROM is not multi-session compatible, and the CD-R was written with multiple sessions or sessions left open.

High Speed recording at 12x and up, actually compresses the cd data track much closer together, thus squeezing 700 MB of data onto the CD media.

The original standard for CD data density, provided for 640MB of data.

Older, low speed cdrom drives, are unable to read the index and data track on a cd recorded at high speed/high density. Due to the data track being far denser than the optics and spindle motor are able to follow.

It is physically impossible.

I have operated a CD Duplication Service for the University of buffalo...and supported cdrom applications and devices since 1994. I am fairly certain of my information.

(Just a comment)

BuffaloDan... You're confusing 650Mb and 700Mb disks. Writing speed is independent of the media used.
