Title: Optical medium reproducing device and method
Inventor: KANEKO SHINJI
IPC: G11B7/005
Filed: 2001-06-26
Abstract: PROBLEM TO BE SOLVED: To effectively reduce the noise in a receiver PD amplifier in a configu ration using a high frequency superposition method to drive a laser light source. SOLUTION: A bottom clip PD amplifier has a current voltage converter 100 to take out the current detected by a photo diode(PD) 1 and convert it into a voltage signal, a clip circuit 200 to clip the laser-off section of the output signal of this current voltage converter 100, and a buffer circuit 300 to output the signal from the clip circuit after converting the impedance. Transistors Q1 and Q2 clip the bottom of a PAM signal to obtain the second PAM signal. Since the amplifier noise is very small to the PAM signal, the bottom noise can be attenuated using a small clip level. Consequently, the amplifier noises can be improved several dBs or more with the same laser power.
