It spins a mylar disk over a read-write head using Bernoulli's principle. The disks appear similar to 3½ floppy disks, and are 13.6 cm wide and 14 cm long. They come in several capacities: 35 MB, 44 MB, 65 MB, 90 MB (late 1980s), 105 MB, 150 MB, and in 1994, 230 MB. There are three types of drives, grouped by the maximum readable capacity: 90 MB, 150 MB, and 230 MB. None of these drives can write to 44 MB disks. The disks have a switch to enable and disable write protection. This article was originally based on material from FOLDOC, used with permission. Update as needed. This article is from Wikipedia.
