Abstract
We have developed high-recording-density phase change optical disks ap plicable to the proposed Super Density Rewritable Disc (SD-RAM) specif ications using the land and groove method. From experiments we confirm ed that GeSbTe phase change optical disks employing this recording met hod have the following tolerances; +/-12/+/-9 mrad for radial tilt dur ing reading/writing; +/-11/+/-8 mrad for tangential tilt during readin g/writing; more than +/-0.07 mu m for offtrack free from cross track e rase.
