Hellp, can my imac read mini dvd?

georgemg,

Welcome to Apple Discussions.

I am in doubt if I can insert these mini dvds inside the disc drive of my Imac, can they be eject?

No!

Read: Apple - Support - Discussions - Can I use mini dvd's in my new imac? for a discussion of why you should avoid using anything but standard-size disks.

Although you are posting in the category for the original iMac G3 with a CRT, it sounds like you have a newer iMac, with a slot-loading optical drive. Do not put any non-standard size disc in a slot-loader drive. It will get jammed inside.

However, there have been a few iMacs with tray-loading optical drives, such as the first iMac G3 models and the iMac G4. You can use non-standard discs, if the optical drive is a tray-loader.

Hellogeorgemg.
As the others have indicated, he small disks could be big problems.
The other 2 posts seem to hit it right on.
IU would like to offer one work around I used.

I had purchased an external Iomega burner for my 350 slot-load.
This burner is like a tray loader, that is it has a tray you drop the disk into.
This works with the small sizes. You could find a burner inexpensive on e-bay
and could help you with the camera usage...........Jim
