How to burn a CD-R disc
A CD-R holds 700 MB (about 80 minutes of audio) — write-once; the best choice for audio CDs and any disc that must play everywhere. Here's how to burn one from your browser with cdBurner, using the drive in your own PC.
Quick facts
- Capacity: 700 MB (about 80 minutes of audio)
- Type: CD-R
- Write-once; the best choice for audio CDs and any disc that must play everywhere.
Step by step
Connect the burn agent
Open onlinecdburner.com. The first time, install the tiny one-time helper so the page can reach your drive — after that it just works.
Insert a blank disc and pick your drive
Put a blank disc in your writer and select it. cdBurner shows the disc type and free space.
Add your files
Click Files or Folder and choose your files. A live gauge shows whether it fits.
Set options and burn
Pick a write speed, keep Finalize on for maximum compatibility, then click Burn disc.
