Abstract

The 4.7 GB digital versatile disc-recordable (DVD-R) disc format has been developed to introduce very useful recordable feature in the digital versatile disc (DVD) family. We developed disc media and the write pulse control method. 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 value of less than 6% using write pulse strategy with the adaptive edge shift control technology. The physical characteristics of the recorded signals satisfy all the requirements of single-layered DVD-ROM disc.
