摘要： A focusing bias adjusting apparatus in an optical recording medium playing apparatus, in which a focusing bias adjustment is executed to remove an offset component in a focusing error signal based on each output signal of a split type photodetector in an optical pickup and, thereafter, a tilt adjustment is executed to an optical system so as to maximize a read signal serving as a sum signal of the output signals of the photodetector in order to compensate a tilt angle which is defined by a normal at the irradiating position of a laser beam from the optical pickup on the recording surface of an optical recording medium and the optical axial direction of the laser beam. When the tilt adjusting operation of the optical system of the optical pickup is performed after completion of the focusing bias adjustment, the focusing bias adjustment is executed again.

摘要： A focusing controller executes an appropriate focus jump even in a multilayer disk having layers of characteristics greatly different from each other. The focusing controller has an optical pickup including an objective lens for converging the light beam and a detector for receiving reflected light from the multilayer recording medium; an error signal generator for generating a focus error signal of the irradiated light beam from a detecting signal of the detector; an actuator for operating the objective lens; and a controller for controlling a focusing position of the light beam by operating the actuator based on the focus error signal. The controller calculates intensities of the reflected lights of two layers based on the detecting signal of the detector, and thus controls the timings of acceleration and deceleration signals of a focus jump between these two layers.

摘要： Disclosed is a focus control apparatus of the present invention capable of successfully performing an accurate focus jump operation without an erroneous operation of a focus actuator. The apparatus irradiates a light beam onto a recording medium, and generates a focus actuator drive signal for moving an optimized light convergence point of the light beam from one recording surface to the other, based on a focus error signal generated based on a returned light from the recording medium. The focus control apparatus comprises a detector for detecting that the focus error signal crosses a predetermined level as a specified level crossing; instruction means for generating a focus jump instruction; a drive signal generating means for generating the drive signal in response to the focus jump instruction and receiving a detection output from the detection circuit to recognize a timing of a specified level crossing of the focus error signal upon receipt of the detection output, thereby extinguishing the drive signal at the timing of the specified level crossing detection timing; and inhibiting means for inhibiting the recognition of the specified level crossing by the drive signal generating section for a predetermined period in response to the focus jump instruction.

摘要： A processor determines whether a prescribed period of time has elapsed or not. When the processor has determined that the prescribed period of time has elapsed, the processor determines whether a mode 0 is set or not. When it is determined that the mode 0 is set, a wireless packet including remote controller button data, remote controller acceleration data and remote controller DPD data is generated. Then, the generated wireless packet is transmitted to a game device. When the processor has determined that a mode 1 is set, a wireless packet including remote controller information including the remote controller button data and the remote controller acceleration data and biological information including previous pulse wave data, present pulse wave data and light reception level data, instead of the remote controller DPD data, is generated.
