New 3.5′′ Magneto-Optical Disk System: 1.3 GB GIGAMO –Technology, Design Concept and Reliability–

Abstract
We have developed and commercialized a new-generation 3.5′′ magneto-optical (MO) disk system, the GIGAMO, which marks the world's first utilization of magnetically induced super resolution (MSR) to realize 1.3 GB capacity and the high performance of up to 5.9 MB/s data transfer rate. The system design and the format are optimized, especially for the purpose of achieving complete downward compatibility with former 3.5′′ MO families from 128 MB to 640 MB media. The improvement of media characteristics and intelligent firmware development of the drive system enable us to ensure usage at various temperature and repeated write/read cycles.
