Abstract
A magnetically suspended CD-ROM drive is proposed, which is characterized by using electromagnetic attraction/repulsion force to move a disc-holding support tray for loading or ejecting a compact disc into or out of the CD-ROM drive. Without employing a gear mechanism of a conventional CD-ROM drive for mechanically operating the support tray, this magnetically suspended CD-ROM drive is beneficial as not having to install additional equipment such as a read/write head moving device, thereby making fabrication processes and equipment maintenance more cost-effective to implement.
