Inventor: HAMAGUCHI TSUYOSHI
IPC: G11B7/09
Filed: 2006-07-12
Abstract: Provided is a detecting circuit which can correctly detect a land prepit signal. A threshold value voltage generating circuit (10) detects an amplitude (V) of a wobble signal (SigWBL) included in a push-pull signal (SigPP), and generates a threshold value voltage (Vth) based on the detected amplitude (V) of the wobble signal (SigWBL). A first filter (12) removes a high frequency component of the push-pull signal (SigPP), and extracts the wobble signal (SigWBL). A peak hold circuit (14) holds a peak value of the wobble signal (SigWBL) extracted by the first filter (12). A second filter (16) extracts a direct current signal (Sig2), which is a direct current component of the push-pull signal (SigPP). An amplifier (18) amplifies a difference (V) between an output of the peak hold circuit (14) and an output of the second filter (16), namely, an amplitude of the wobble signal (SigWBL).
