Sadly, you can't erase CD-R's. Once the data has been burned on the CD-R disc, it essentially becomes a CD-ROM; It all comes down to how data or music is written to a CD-R vs. a CD-RW.
When your CD burner writes to a CD-R disc, the laser physically etches the data into the disc by exposing dots and dashes on a material somewhat reminiscent of photographic film.
When your CD burner writes to a CD-RW disc, your laser becomes less intense and creates dimples in a layer of dyes with in the disc. The reason some older CD players wont play CD-RWs is that the dimples don't reflect the laser as strongly as etches. The reason you can erase CD-RWs is that you can smooth the liquid layer over again and create dimples again, up to 1500 times.
Since the data burned onto a CD-R is bespoke to the actual disc, the only way to destroy the data is to destroy the actual disc.
The best way to destroy a CD-R disc is to place the CD, label-side up, on the pavement or gravel, put your foot on top of the disc and scrape the CD Backwards with your foot. This effectavely destroys the data layer and therefore, the data stored on it.
WARNING: Never, ever bend a CD to destroy it. I one time bent a skipping MP3 CD in the car once as it was bugging me, it shattered into a million pieces of sharp flying polycarbonate! I arived home with my hands bleeding and a car full of CD dust. For 2 weeks after, running the AC would result in a sprinkle of CD dust coming out the vents!
