Abstract
Phase-change optical disks showed available cross talk characteristics even the signals are recorded on tracks with 0.8 μ m pitch using land and groove recording method.(1) In this paper, the results of a feasibility study of high track density recording for rewritable disk system are reported. The influence of adjacent tracks overwriting upon cross talk and jitter were measured for various track pitches using a 680nm laser diode and optics of NA 0.6.
