Is it possible while the disc in the cd-rom drive is read and another one disc in the cd-rewriter is recorded simultaneously? or there run sequencely, one after another? (after read finished then only write/record)

if run sequencely, so the cd-rom drive is no use anymore? extra? just one cd-rewriter well do, right? :confused:

Yup, you can use the CDROM as the reader and burner as writer to read and write at the same time. That's what they call burn "on-the-fly".

You can also use only the burner, but you'll need to make an image file on HD then burn from it.

Hi, van, you means there run sequencely? must the one read finished then only can write, correct? the image file was created automatically when i'm write?

and..., do the (write options) disc copy use more disc space compared to audio copy?

:beer: for u! thanks.

No, m8! Let me make it a bit clearer for you.

If you use 2 drives, the CDROM to read the source CD and the burner to write the target CD, you can read and write at the same time. You do not need to wait for the reading to complete before you can burn. Provided that the CDROM is fast enough to burn at your desired speed.

If you use only the burner, you can't read/write at the same time. You must first read the source CD and write to the HD (normally the image file of the source CD) then take the source CD out of the burner, insert a CDR into the burner and burn from the image file on HD.

Please tell a little more, what burnware are you using, so that people can easily help you. Maybe giving you a step by step instruction.

oh! i see. actually i'm not really remember what software that i used. it is my friend's burner. i think is Primo (provided by acer, the burner is acer 12x)

I do not use Primo so can't go into specific details. But all burnware have Disc Copy option for copying discs. Just insert the source disc in the CDROM and a blank CDR in the burner and do a Disc Copy. It's recommended to run a test burn for the 1st time to see if you can successfully burn at the speed that you set (sometimes the CDROM is too slow for that speed).

And all burnware will have the option for you to make an image of the source CD on the HD then burn to the target CD from that image. Because the HD is much faster than CDROM, this is a safer method but takes longer time.
