LMSI produced 5.25" magneto-optical drives as well. Maxoptix, a spin-off of Maxtor Corp., was a major manufacturer of 130 mm or 5.25" magneto-optical drives. A current model is the T7-9100 drive, which has a maximum capacity of 9.1 GB and is downward read and write compatible with 5.2 GB, 4.8 GB, 4.1 GB, 2.6 GB, and 2.3 GB magneto-optical disks ...
MD Data is a type of magneto-optical medium derived from MiniDisc. [ 1 ] In developing and marketing it, Sony was trying to set the new standard for removable media to replace the 3½-inch diskette it had also helped create.

MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, and later, 80 minutes of digitized audio. Sony announced the MiniDisc in September 1992 and released it in November [2] of that year for sale in Japan and in December in Europe, North America, and other countries. [3]
Magneto-optical recording writes/reads optically. When writing, the magnetic medium is heated locally by a laser, which induces a rapid decrease of coercive field. Then, a small magnetic field can be used to switch the magnetisation. The reading process is based on magneto-optical Kerr effect. The magnetic medium are typically amorphous R-Fe-Co ...
Hi-MD is a magneto-optical disc-based data storage format. It was a further development of the MiniDisc. [1] With its release in later 2004, [2] came the ability to use newly developed, high-capacity 1 gigabyte Hi-MD discs, in the same dimensions as MiniDisc. [2] The last recorder and player was discontinued in 2011. [3]
However, not all optical drives provide this capability, and support for this feature can vary significantly between manufacturers and drive models. On drives lacking raw data access, users may rely on a less precise method: monitoring unexpected reductions in read speed, though this is a far less reliable indicator of disc health.
Magneto-optical drives use sector sizes of 512 and 1024 bytes on 5.25-inch drives and 512 and 2048 bytes on 3.5-inch drives. In CHS addressing the sector numbers always start at 1 , there is no sector 0 , [1] which can lead to confusion since logical sector addressing schemes typically start counting with 0, e.g., logical block addressing (LBA ...
