Magneto-optical disks are a type of optical disk for data storage available in 5.25-inch and 3.5-inch formats. The 5.25-inch version entered the market in 1985; the 3.5-inch version has been around since 1991. Magneto-optical disks were considered to be very reliable because their reading equipment always checks that the data is written without any errors during the writing process. This however resulted in them being very slow to write on. The 5.25-inch disks had a capacity of 256 MB up to 9.2 GB, distributed over both sides of the disk. The 3.5-inch disks had a capacity of 128 MB up to 1.3 GB, and could only be written on one side.
