To obtain high bit density on a phase change optical disc, it is essential to understand what are the dominant physical effects to record marks on PC media. Computer simulation is one of the most convenient methods to consider an appropriate physical model of such a mark forming process. The authors have studied computer simulation of phase change mark(More)
A rewritable digital versatile disk (DVD-RAM) has eight times more capacity than a CD-ROM disk, which makes it promising for use as a computer file memory device. Media compatibility is realized because a DVD-RAM uses the same write/read wavelength as the DVD-ROM, the same substrate thickness (the DVD-ROM disk uses a thin 0.6 mm-thick substrate so it can(More)
