16x dvd drives

SuperDrive is a term that has been used by Apple Computer to refer to two different storage drives: in the late 1980s to a high-density floppy disk drive; and later to a combined CD/DVD reader/writer.

Floppy disk drive

The term was first used by Apple Computer in 1988 to refer to their 1. 44 MB floppy drive. This replaced the older 800 KB floppy drive that had been standard in the Macintosh up to then, but remained compatible in that it could continue to read and write both 800K (double-sided) and 400K (single-sided) floppy disks, as well as the then-new high-density floppies. This drive was also capable of reading and writing MS-DOS formatted disks with appropriate software, unlike the 400K and 800K drives. This was made possible as the SuperDrive now utilitized the same MFM (Modified Frequency Modulation) encoding scheme used by the IBM PC, yet still retained backwards compatibility with Apple's GCR (Group Code Recording) encoding format, so it could continue to read Macintosh MFS, HFS and Apple II ProDOS formats on 400/800K disks.

The SuperDrive was known primarily as an internalized floppy drive that was a built in part of the Macintosh computer; however, an external version of the drive was manufactured that came in a stylized plastic case. DVD Drives for Less.
