CD-R - Is it possible to add files after a first burn?

Answer 1

Yes, on newer update xp and vista operating systems you can even erase them. I do it all the time erasing cd-r instead of buying cd-rws.
hell ill even make a video of me doing it, if that is needed.\

(another note)

ahotman & spaced are on the right track, but honestly you can go out and buy a 50 pack of cd-rs for 10 dollars and if you need to re-write them It works perfectly. I never personally had ANY compatibility issues erasing a cd-r up to 5 times, but I never had to erase it more than 5. I do it all the time works fine, just get windows xp sp2 update or windows vista and everything should be fine.

I have gone a year burning and erasing on just 50 cds after i figured out i was wasting money on cd-rws that do the same thing.

(Simply)The reason why the new op system updates and vista can erase cd-rs is because they really just over write them with "blank data" which is pretty much what a cd-rw do.

I hope this helps.

Answer 2

CD-R can be added to as many time as you like up until the capacity of the disc but only if you have left the disc open to multi session. In your software there will be an option for this. If you chose to close the CD after burning, then despite how much space is left on the disc you will not be able to add more files or music tracks to it.

This is the same with CD-RWs although they can of course be formatted and used again unlike CD-R which are one write only.

Hope this helps.

-----It's also worth pointing out that you will not be able to play audio tracks on a standard CD player until the CD has been closed which would mean no more tracks can be added. This also goes for Re-Writable discs. They still need to be closed before playing on a CD player.----

Although CD audio tracks can be played on the computers drive even before the disc is closed and if it's just files, it makes no difference as they will only be accessed by the computer drive not a CD player..

Answer 3

Yes , you can. Its a simple trick , it works on any CD-R.

First if you burned the CD with Nero then add the files using windows own burner. if you used windows own built in burner to write the CD, then use Nero to add the files later. Some CD-RW drives can view both previous and later sessions at once. If it does not, then use ISO buster to read the files of the CD.

Answer 4

Unfortunately not. The data is added to CD-Rs and CD+Rs (Compact Disc Recordable) in a simple way: the surface of the CD is engraved with pits and bumps, like small, precise scratches in the surface. This contains the information for the computer to read. The pits refer to the binary 'zero' and the bumps to the binary 'one'. As the disc is read, it produces a huge string of zeros and ones, which the computer interprets into commands. Once this has been performed (the data being added to the disc), it cannot be changed. The metal used for the disc will have crystallised and will be impossible to change, hence the ability to only use them once.
In CD-RWs and CD+RWs (Compact Disc ReWritable), the material used for the disc is different. The means of adding data is the same, however, once the metal (most often AgInSbTe) has crystallised, it is possible for it to decrystallise and have data rewritten. This is done by adding an infra-red laser beam, employed to selectively heat to melt the crystallised recording layer into an amorphous state, or to anneal it at a lower temperature back to its crystalline state. The different reflectance of the resulting areas make them appear like the pits and bumps of a pre-recorded CD.

Answer 5

I would say that it is possible to add further files to it as long as you have space and you have Multi Sessioned it as well. If you have not choosen the Multi Session then you are stuck with what you have.

I have done Multi Sessions on CD-R's and i have had no problems with them further down the line when wanting to use them or add files to it at a later date. Most software allows you to do this and in some cases ask you if you want to Multi Session the CD before recording.

Hope this answers your question

Answer 6

Yes--at least with XP if the disk has been formated as a data storge disk and there is free space.

Simply right click the icon fo the file you wish to save and the drop down menu will appear. Choose "send to" and then click on the drive which is your CD burner. You will be prompted on the lower property bar that there are files waiting to be saved to that specific drive.

You can also drag and drop the aforementiond icon to the drive icon in the "my computer" dialogue box and follow the final steps--which will propt you to burn the file(s) to the CD.

Answer 7

You can if you record the CD as a multi-session disc. This in effect lets you add files to the disc later. This then gives a 'tree' structure to the cd (similar to folders on a hard disc)

Answer 8

Disc At Once - the whole CD-R is written in one session with no gaps and the disc is "closed" meaning no more data can be added and the CD-R effectively becomes a standard read-only CD. With no gaps between the tracks the Disc At Once format is useful for "live" audio recordings.
Track At Once - data is written to the CD-R one track at a time but the CD is left "open" for further recording at a later stage. It also allows data and audio to reside on the same CD-R.
Packet Writing - used to record data to a CD-R in packets allowing extra information to be appended to a disc at a later time or information on the disc can be made "invisible". In this way CD-R can emulate CD-RW however each time information on the disc is altered more data has to be written to the disc. There can be compatibility issues with this format and some CD drives.

Answer 9

CD-R means 'cd rightable' and so you can only use it once. CD-RW means 'cd re-rightable so you can use it again and again. Sorry it is not possible to add files after the first burn of a CD-R. You will need to use CD-RW

Answer 10

if you select a mulitisession option at the time of burning and there is space left n the cd-r then it is possible....but the best thng is to buy a cd-r w which can be used as many times as u like..
