• If you are currently using one capacity of magneto optical disk - it is best to order the same size.
**unless you are certain that your drive can handle a larger capacity.
• "Magneto Optical Disks" are commonly referred to as "MOD", "MO disks", and "Optical Disks"
• Both "disk" and "disc" are common spellings when referring to optical media.
• "Capacity" refers to the amount of data that may be stored on a disk.
• There are two sizes: 3.5 inch and 5.25 inch.
• 5.25 inch magneto optical disks can be either WORM (write once read many) or RW (rewritable)
• They are manufactured to ISO specifications - in other words, if a 2.6gb Sony disk works in your system so will disks from other manufacturers like, MaxOptix, Medical Grade, & Philips, that match the same specs.
• It is important to make sure that the disk you are purchasing has the same bytes per sector as the one you are currently using.
• Pioneer is the only magneto optical drive manufacturer that utilizes a proprietary format. If you have a Pioneer drive you will need to purchase Pioneer brand products.
• The capacity of disk that you can use is determined by the drive.
• For example: If you have a 230mb 3.5inch drive you cannot use a larger capacity disk; only disks that are 230mb or smaller (128mb) will work with your drive. The same is true with the 5.25 inch disk. If you have a 5.2gb MO drive you will not be able to use the larger 9.1 gb magneto optical disk.
• Drives are backward compatible. For instance a TMT7-9100 MaxOptix MO drive can read data from discs that are 600mb up through 9.1gb; and can write data onto magneto optical disks that are 2.3 gb through 9.1 gb.
• 2.3GB is the most common capacity; and comes in both 3.5" and 5.25" physical sizes.
• When replacing a legacy drive it is considered best practice to match both the drive and firmware
