The recording capacity of GIGAMO media was enlarged from 1.3 GB to 2.3 GB for 3.5 inch Magneto-Optical (MO) disks while maintaining downward compatibility. For the new GIGAMO technology, a land and groove recording method was applied in addition to magnetically induced super resolution (MSR) media. Furthermore, a novel address format suitable for the land and groove recording method was adopted. The specifications of the new GIGAMO media were examined to satisfy requirements for practical use with respect to margins. Durability of more than 106 rewritings and an enough lifetime were confirmed.
