• 論文の詳細を見る

• The effect of the side-wall-annealing process on the domain wall mobility of a track-wobbled DWDD disc was investigated. Using a red laser and NA of 0.60, we obtained sufficiently low bit error rate and wide recording power tolerance on a one-side-wobbled land/groove substrate. Furthermore, wide tolerance of groove duty for characteristics of both MO and address was obtained. Track-wobble has no influence on the domain wall mobility and the side-wall-annealing technique is useful even for a track-wobbled high density DWDD disc.
