The CD-ROM or DVD drive in the Clamshell iBook is disguised to an extent that you can hardly believe that a standard drive lies underneath the cage which holds it in its place. You can dismantle the drive and use even a DVD burner as long as you make sure that it is set to master or cable select.
All parts are either screwed and / or glued together. You need a philips screwdriver, a good scraper and a spatula. Removing the white spacer pad needs your special attention.
The picture shows the attachments (without bezel), which must be dismantled.
6 screws - 4 on the side, 2 on the ribbon cable
2 Metal fleece pieces
1 spacer spring
1 flat ribbon cable
1 flat white spacer pad (remove carefully with scraper)
The cage and the flat cable are slightly glued to the drive, use a spatula.
