ELECTRONIC CIRCUIT FOR DECODING READ-OUT SIGNAL FROM OPTICAL STORAGE MEDIUM, ELECTRONIC APPARATUS FOR READING OPTICAL STORAGE MEDIUM, METHOD FOR READING OPTICAL STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide an optical storage medium, an electronic circuit and electronic apparatus improved for especially reading a blue-ray disk, a suitable method, and a computer program thereof. PSOLUTION: This electronic circuit comprises a limit equalizer for amplifying the high-frequency read-out signal components without substantially increasing the inter-symbol interference, and a Viterbi detector connected to the output side of the limit equalizer for supplying the decoded read-out signal.
