-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 consistenly stable performance, thanks to the adoption of Sony´s own Wide Margin Recording Film, which can accomodate 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-Change. 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 slide. Also, Sony´s original antistatic hard coat treatment cuts down on static electricity and protects the disk surface from scratches and dust.
