Techniques for reading DVD-RAM disc with DVD-ROM drives

Katsuhiko Izumi; Kunikazu Ohnishi; Masayuki Inoue; Takeshi Shimano; Yasuyuki Sugi

We have developed techniques to read DVD-RAM discs with DVD-ROM drives. The key techniques are the reduction of feedthrough in the focusing error signal, the reduction of the push-pull signal offset, and the half tracking jump function.
