概要
- 論文の詳細を見る
The complementary allocated pit address (CAPA) signal in a digital versatile rewritable disc (DVD-RAM) is susceptible to an objective lens radial shift; the reduction of its signal amplitude occurs and the S/N ratio decreases. To alleviate this situation, we propose a new readout signal processing scheme, the center separate detection method (CSD) of discarding a large amount of the 0-th diffracted light beam from the disc. We confirmed the expected results by numerical simulation.
