Notes: The outer packaging of the 5-disc set will be opened (the disc packages are unopened). A must-have for retro PC users and MO drive users! We are offering a set of 10 230MB MO discs made by Teijin (TEIJIN). Capacity: 230MB Quantity: 10 discs (5-disc pack x 2) Condition: The discs are new, but the original outer packaging of the 5-disc pack will be opened, and only the discs will be sent. This is recommended for those who do not care about the outer packaging and just want to use the discs themselves. The discs themselves are new and unused, and have been carefully stored in a dark place for a long time. Features: Unused items are very rare because production and sales have ended. How about using them for data backup, MO drive operation check, or collection? [Product Overview] Manufacturer: Teijin (TEIJIN) Capacity: 230MB Standard: 3.5-inch MO disc MO discs were once used as the "successor" or "large-capacity version" of floppy disks, but the data recording method and capacity are significantly different.
