Abstract

The DVD-RAM, now a world standard among rewritable high-capacity optical disks, is expected to have wide applications in the PC and AV fields. However, when a recording and reproducing optical disk’s surface is soiled with fingerprints or dust, generally some writing error can be happened. As a solution to this problem, this paper presents the method for controlling recording laser power to improve recording reliability.
