Paper Abstract

For multi-media applications, a higher density rewritable optical disk with a reduced track pitch becomes extremely important. To narrow the track pitch, increasing the groove depth of the land/groove recording type optical disk has been proposed. Not only magnetooptical recording systems but also phase-change recording systems can be applied to the deeper groove technique which gives wider recording power margin in addition to the cross-erase suppression, so that the high density rewritable optical recording systems will be steadily realized without shorter wavelength laser diodes.
