  • Publication number: 20070008842
    Abstract: According to an optical disk device of the present invention, in the drive operation, when a detection circuit detects an electric wave coming from an outside radio equipment, and a comparison circuit detects that the voltage of the electric wave is equal to or over a predetermined threshold level, in case it is determined that data is being reproduced from or data is being recorded to a record type medium, a CPU controls a laser drive circuit to temporarily turn off the output of laser from an optical PUH. On the other hand, in case it is determined that data is being reproduced from a read type medium, the CPU controls the laser drive circuit to enhance the power of laser of the optical PUH to improve the S/N ratio.
