开发了 DVD－ RAM驱动器。其容量与 DVD－ ROM(Video)相同 (4.7 GB)，记录和读出时的传输速率为 22.16 Mbps。该驱动器通过新开发的单镜集成化记录用光头、光道中心控制 /倾斜控制及加强的记录系统学习功能，实现了 4.7 GB的高密度记录所要求的功能，如高精度控制及兼容性、适应盘片各种变化的稳定的记录性能。而且，该驱动器还兼容 2.6 GB DVD－ RAM盘的记录 /读出、 DVD－ ROM和 CD－ ROM盘的读出。
Developed DVD-RAM drive. It has the same capacity as DVD-ROM (4.7 GB) and a transfer rate of 22.16 Mbps for recording and reading. The newly developed single-lens integrated recording head, track center control / tilt control and enhanced recording system learning function enable the 4.7 GB of high-density recording functions required such as high-precision control and compatibility, Adapt to the steady changes in the recording performance of the disc. Moreover, this drive is also compatible with recording / reading of 2.6 GB DVD-RAM discs, reading of DVD-ROMs and CD-ROM discs.
