Sony 5.25" Magneto Optical Media 5200MB 5.25" magneto optical disk

13.335 cm (5.25 ") Magneto Optical Media Huge Storage Capacity of 9.1GB, thanks to MSR Technology and Land & Groove Recording

Huge Maximum Storage Capacity of 9.1GB
With the adoption of MSR (Magnetically induced Super Resolution) technology and Land & Groove Recording, the 14X MO disk has a maximum storage capacity of 9.1GB -- in other words, 14 times (14X) the 650MB capacity of the first-generation MO disk.

High Reliable Suitable for a Variety of User Environments
The 14X MO disk offers consistently stable performance, thanks to the adoption of Sony's own Wide Margin Recording Film, which can accommodate fluctuations in the laser power of a variety of user environments, as well as a high-precision stamper and molding technology. It also offers at least one million erase/record cycles and a reading life estimated at more than 50 years, making it suitable for long-term data preservation.

Superior Durability For Use in Auto-Changers
The use of Sony's own cartridge design and mechanical parts gives the 14X MO disk as many as 100,000 load/unload cycles per side. Also, Sony's original antistatic hard coat treatment cuts down on static electricity and protects the disk surface from scratches.
