The 4.7 GB digital versatile disc-recordable (DVD-R) disc format has been d
eveloped to introduce very useful recordable feature in the digital versati
le disc (DVD) family. We developed disc media and the write pulse control m
ethod. In our examination. recorded signal qualities of the DVD-R disc are
equivalent to those of the DVD-Read-Only disc (ROM). We realized a jitter v
alue of less than 6% using write pulse strategy with the adaptive edge shif
t control technology. The physical characteristics of the recorded signals
satisfy all the requirements of single-layered DVD-ROM disc.
