Ask Max: Can you insert one of those small 3
As an owner of two iMacs purchased through PowerMax, I hope you don't mind a really simple question: can I insert and play a small (3" diameter) DVD--assuming it's formatted for Macs--into the right side slot, or will it lodge inside?
I am happy you asked before trying it. Mini sized CDs or DVD s should never be used in any slot-loading drive. This is true for Apple computers and car stereos. Really they are a terrible idea and should have never been produced. Currently only tray based drives will accept them, and the tray has to have a special indent to keep the small disc centered.
This idea came out of the initial high cost of creating a full sized CD. Now that cost is pennies so making it smaller does not reduce the cost appreciably. The best way to get data off those disc, is to find a tray loading drive and transfer the data to a USB thumb drive or full sized CD-R.
Many service techs has had to extract those little discs from a drive, at great expense.
