The erasable optical disk with highrecordingdensity, high stability, high data transfer rate, high carrier-noise ratio and low error rate arc the main points in the research and development.
Readback voltage of perpendicular recording for high track density with ring-type head is theoretically calculated, and rcadback noise is analysed.
本文从理论上对高道密度垂直磁记录环形头读出电压进行了计算,并对道间串扰进行了分析。
