Two years later, the double-sided drive brought 800 KB disks into light, followed by the 1.4M SuperDrive in 1988.* The 2.8 MB extended density disks were never brought to the Mac (nor were they popular on IBMs). The first disks were single-sided and held roughly 400 KB of data. When the Mac came out in 1984, the floppy disk was the only type of storage medium available.

Scott Baret wrote and drew the original work in 1995 at the age of eight and began revising it a year ago.

As for what kind of software you need to do the translation … oops, sorry, gotta pick up the cat at the chiropractor. But maybe what you wanted to know was: can I _read_ a Mac disk in a PC? No, not unless you’ve got special software, since the formatting is different. So, can you use a Mac disk in a PC? Sure. On a Mac, you get a prompt warning you that the disk isn’t formatted correctly, and asking whether you wish to do so.) (On an IBM-compatible, this is as simple as typing – at a DOS prompt – format a: and hitting enter. If you take a blank 3.5″ floppy disk – even one formatted for IBM-compatibles or for Macs – and slap it in your 3.5″ disk drive, it’ll work in either one, provided you format it yourself. Physically PC and Mac disks are the same. It’s important to keep in mind here that a floppy disk – of any stripe – is merely a recording medium. If there is no difference, can they be used on the other computer? Justin Last
Dear Straight Dope: What is the difference between the 3.5 inch disks used in Macintosh computers and their clones and the 3.5 inch disks used in IBM’s and their clones.
