document: Development of a 3.5 inch magneto-optical disk with a capacity of 2.3 GB The recording capacity of GIGAMO media was enlarged from 1.3 GB to 2.3 GB for 3.5 inch magneto-optical -LRB- MO -RRB- 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 -LRB- MSR -RRB- 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 10/sup 6 / rewritings and an enough lifetime were confirmed
