Abstract

Two new recording technologies, land and groove recording and mark edge recording, have been developed to achieve the largecapacity phase-change rewritable disk. As a result , high-density recording has been made possible at track pitch 0.74 pm and bit length 0.41 pmhit. These technologies can realize a broad margin for radial tilt and adjacent track erasing.
