Paper Abstract

We propose a new wide-band laser noise cancel technique which is especially effective in Blu-ray Disc system because of its laser noise increasing compared with conventional optical disc systems. Laser noise cancellation method has already been available, but it is difficult to extend the noise suppression bandwidth for high-speed reading. So we examined the realization possibility of wide-band noise canceling and developed a new photo diode IC (PDIC) with noise cancel function based on our principle examinations. Big advantages in respect of the cost and space are expected to be obtained by adopting this technology.
