    • 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.
    • 一种光盘装置,包括:读取单元,用于通过向光盘照射激光并检测光检测器中的反射光,输出作为记录在光盘中的数据的读取信号的RF信号; 均衡单元,用于对作为读取单元的输出的RF信号进行均衡调整; 播放单元,用于从已经经过均衡单元的均衡调整的RF信号产生重放信号并输出​​回放信号; 参数存储单元,用于存储用于均衡单元的均衡调整的参数的初始值; 以及参数检测单元,用于检测至少一个参数的值,在所述至少一个参数中,在所述光盘的重放期间已经经过均衡单元的均衡调整的RF信号的抖动变得最佳。
