As the other said.. NO! I was at the Genius Bar last week and a lady brought in her macbook with a stuck mini-cd. The Genius held it with the superdrive down and gently knocked on the top until the mini-cd was showing enough to remove it. Heard him said, you don't want to do this as this drive is made for full size cd/dvd's.
Generally, slot-loading drives should only be used with full-sized discs unless the manufacturer specifically says another particular size is ok (like with the Wii)
