Recording and reproducing method for dye-based recordable DVD medium and apparatus for the same
摘要:
To provide a recording and reproducing method for dye-based recordable DVD media, including: recording a mark of the shortest length on a dye-containing recording layer of a dye-based recordable DVD medium using single pulse whose front edge is energized; recording marks other than the shortest thereon using single pulse whose front and rear edges are energized for a given duration, the power of the front edge of pulse being equal to that of the front edge of pulse for the shortest mark, the power of the rear edge of pulse being equal to that of the rear edge of pulse for the shortest mark; and reproducing recorded information using a reproduction beam, wherein the irradiation intensity of cooling pulse provided after the rear edge of pulse upon mark recording is 0.1 mW or less for a given duration, and the recording linear velocity is 42 m/s or more.
