Abstract:
An information reproduction apparatus comprising:an extraction device for extracting a reproduced signal that reflects data recorded on an information recording medium; anda reproduction device for generating a slice level signal based on a predetermined signal included in the reproduced signal extracted by said extraction device, generating a binary signal obtained by binarizing the reproduced signal based on the slice level signal, and reproducing the data recorded on said information recording medium based on the binary signal, wherein said extraction device comprises:a reproduced signal generation device for generating the reproduced signal, which reflects data recorded on an information recording medium having a header field containing address data, and a recording field containing recording data, from said information recording medium, andsaid reproduction device comprises:a slice level signal generation device for generating the slice level signal based on a predetermined signal included in a reproduced signal of said header field in the reproduced a signal generated by said reproduced signal generation device;a binary signal generation device for generating the binary signal by binarizing the reproduced signal generated by said reproduced signal generation device based on the slice level signal generated by said slice level signal generation device; anda data reproduction device for reproducing data recorded on said information recording medium based on the binary signal generated by said binary signal generation device.
