- 論文の詳細を見る
The effects of placing a shading band in the collection path of a magneto-optical data storage device are presented. The shading band consists of an opaque region in the center of the collection aperture, which reduces the low-frequency response of the system without affecting the high-frequency response. This partially equalizes the system transfer function. Dynamic measurements indicate that the noise is also reduced in the low-frequency region, thus not significantly affecting the narrow-band carrier-to-noise ratio (CNR). The integrated signal-to-noise ratio (SNR) shows slight improvement in the high-frequency region.
