- Using the Drive and Disks section.
- · Added to the List of Amiga MO Users section.
- · Added SFS mount files, and reorganised mount files in DOSDrivers drawer
- into subdirectories.
- · Added FFS & SFS mount files for 600MB 5¼" disks.

- · Various other changes.
-
-
- Here are some extracts from the FAQ.
-
-
- Introduction
- ------------
- The Amiga Magneto-Optical Drive FAQ contains information about using magneto-
- optical (MO) disk drives with the Amiga. It is freely distributable.
-
- I hope the availability of this document will encourage more Amiga users to
- consider optical storage, instead of fragile magnetic media like Zip, Jaz and
- SyQuest.
-
-
- What are Magneto-Optical Disk Drives?
- -------------------------------------
- Magneto-optical ("MO") disk drives are versatile removable storage devices,
- which use very robust and inexpensive media. You can use an MO disk just like a
- large floppy disk, or like a hard disk.
-
- Sony's increasing popular "MiniDisc" system uses a type of magneto-optical
- disk.
-
- Magneto-Optical storage has many advantages over other types of removable media:
-
- · Media life is at least 30 years, which greatly exceeds the life of magnetic
- media like floppy disks, Zip and Jaz disks. Some manufacturers quote media
- life of 50 or even 100 years. Data can be rewritten at least a million
- times, and read at least 10 million times; some manufacturers quote figures
- ten times this. This figure also exceeds that for magnetic media.
-
- · There is no physical contact between disk surface and drive head, so there
- is no possibility of data loss through a head crash.
-
- · MO drives are backwardly compatible, which means that if you upgrade your
- drive in the future, you will be able to read and write all your existing
- disks on the new drive.
-
- · MO disks are not susceptible to magnetic fields.
-
- · If, for example, you spill a cup of coffee on an MO disk, you can clean the
- disk surface and continue to use the disk. Cleaning kits are available for
- both MO drives and disks. Disk cleaning kits are very cheap.
-
- · MO disks are simple in construction, unlike some other kinds of removable
- media which may contain moving parts. This is another reason why MO offers
- greater reliability than magnetic media.
-
- · MO disks are available in several different capacities, which vary in
- price. Cost per megabyte is lower than all other kinds of random access
- removable media.
-
- · Unlike Zip, Jaz, SyQuest etc., MO drives and disks are not proprietary, and
- they are made by many companies. The disks are covered by various
- international standards. So you will not be stuck if your drive
- manufacturer goes bust, as happened recently to SyQuest.
-
- · Compared to other forms of optical storage, there are no restrictions on
- writing and rewriting data to MO disks, unlike CD-R or CD-RW. Also unlike
- CD-R & CD-RW, since the disk itself is protected by a plastic casing, there
- is no danger of data corruption due to the disk getting scratched.
-
- · MO drives normally automatically verify written data to guarantee data
- integrity. There is no such verification with CD-R and CD-RW, so to be
- assured that the data has been written properly when using these, you would
- need to manually compare all copied files.
-
- · Magneto-optical technology is well-proven. I believe the first 128MB 3½" MO
- drives were available in 1992. 640MB drives have been available since 1996.
- Originally MO was largely restricted to professional use due to high drive
- cost, but over the past couple of years this situation has changed.
-
- · MO disks are convenient, compact and easy to use. 3½" MO disks are the same
- size as two floppy disks stacked on top of each other. They have a
- write-protect tab which works just like a floppy disk's.
