Popis:	Current status of high density recording on phase change optical disks is summarized. More than 4.1 Mbits/mm2 density of direct overwriting on phase change disks was achieved using red (680 nm) high power (35mW) LDs, large NA (0.6) optics, thin (t0.6 mm) substrates, mark-edge recording with write compensation, and land-groove recording technologies.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
