ABSTRACT:
In a system in which a signal is read out of a medium for recording binary-coded information data, an information signal having no dc component is detected, and the information signal is compared with a slice signal to detect a series of binary-coded signals. The system includes a slice signal generating circuit for detecting an envelope of the information signal and generating a slice signal on the basis of the detected envelope signal such that the voltage level of the slice signal corresponds to a dc voltage level of the information signal when the information signal is being read and the voltage level thereof is higher than the noise level when the information signal is not being read.
