    摘要: A light emitting element drive circuit which has high operation speed, low current consumption and provides an optical output signal with minimum distortion. An inverted input signal is applied to a second transistor which drives a differentiating circuit. The differentiating circuit drives a third transistor which provides a current path for discharging the light emitting element. The light emitting element discharges when the input signal falls. The input of the differentiating circuit and the input of the light emitting element drive circuit are isolated to prevent "back gating" distortion of the optical signal.

    摘要: A device for driving and controlling an optical head by forming a spot of a light beam on an optical disk having a plurality of tracks and detecting light from the spot reflected on the optical disk by a pair of optical detectors disposed in the head. This device has: a head actuator for moving a movable portion of the optical head in the radial direction of the disk; a speed detector for detecting the track-crossing speed of the spot from outputs from the optical detectors; a reference speed generator for generating, while accessing to a target track, a reference moving speed signal in accordance with the distance to the target track obtained from the outputs from the optical detectors, the movable head portion being moved on the basis of the reference moving speed signal so that the speed of the movable portion decreases at a position near the target track before the light beam spot reaches this track; a speed error detector for obtaining the difference between outputs from the reference speed generator and the speed detector; and a magnification change circuit adapted for amplifying the outputs from the reference speed generator and the speed detector by a predetermined multiplying factor when the distance between the light beam spot and the target track, or the crossing speed of the spot, becomes smaller than a predetermined value, the magnification change circuit also being adapted for outputting the difference obtained by the speed error detector after multiplying it by the reciprocal of the multiplying factor. The head actuator is driven on the basis of the output from the error detector so as to control the speed of the movable head portion.

    摘要: It is expected to provide an optical communication module that can avoid the reduction in the performance of light communication when an edge emitting type photoelectric device is mounted. The optical communication module is configured to include: a basement where a convex first and second lenses are integrally formed on the upper and lower surfaces, respectively; and a laser diode aligned with the first lens on the upper surface to emit light in the direction toward the first lens. It is configured that the first lens refracts the light emitted from the laser diode to become substantially parallel to the upper surface of the basement and the refracted light is reflected toward the direction of second lens.
