摘要：

The read-out signal in an alloying disk, which has a large phase difference of the reflection coefficient between nonrecorded and recorded states, was analyzed by taking into account the effects of grooves. It was found that the read-out signal can be enhanced by interference between light reflected from a groove and recording media. A 60-dB CN (carrier-to-noise) ratio was obtained by applying this idea to the Sb2Se3/Bi alloying disk. NTSC (National Television System Committee) direct FM signal recording was confirmed by using this disk. It can be read by a modified Laser Disc player system.
