Patent attributes
An optical disc apparatus includes: a read unit for outputting an RF signal, which is a read signal of data recorded in an optical disc, by irradiating a laser beam to the optical disc and detecting reflected light in a photo detector; an equalize unit for performing equalize adjustment on the RF signal, which is an output from the read unit; a playback unit for generating a playback signal from the RF signal having undergone the equalize adjustment by the equalize unit and outputting the playback signal; a parameter storage unit for storing initial values of parameters used for the equalize adjustment by the equalize unit; and a parameter detection unit for detecting a value of at least one parameter at which jitter of the RF signal having undergone the equalize adjustment by the equalize unit becomes optimal during playback of the optical disc.
