The FileWare disk was a higher performance alternative to the Apple II and Apple III-compatible disks. It was developed for many Apple computers of that time, but only one, the original Lisa, shipped with them. They are better known by their codename, "Twiggy".
Differences
The differences between the FileWare disks and standard 5 1/4" disks were:
- Instead of one head, there are 2 heads.
- The drives were different that the top and bottom heads are on opposite sides of the spindle, and each is opposed by a pressure pad. Since there is only one actuator to move the heads, when one head is near the spindle, the other is near the outer rim of the disk.
Reliability
The disks and drives proved unreliable, and by 1984, the Lisa's 2 FileWare drives were replaced by a single 3 1/2" drive manufactured by Sony. NOTE: The Macintosh prototypes had FileWare drives too, but it was replaced too.
