摘要： An optical pickup device includes an optical system which forms a main spot and a set of sub-spots on an optical disk by a beam of light passing the optical system. A photodetector unit outputs first signals in response to a reflection beam from the main spot, and outputs second signals in response to reflection beams from the sub-spots. A tracking error detector includes a first detection circuit designed to output a first tracking error signal for a first track pitch, and a second detection circuit designed to output a second tracking error signal for a second track pitch different from the first track pitch. A switch selectively connects one of the first detection circuit and the second detection circuit to an output of the tracking error detector in response to a track pitch of the optical disk, so that one of the first and second tracking error signals appropriate for the track pitch of the optical disk is output.

摘要： A polarizing beam splitter for separating an upstream beam from a downstream beam according to the polarization of an incident beam is provided between first and second light sources emitting laser beams at respective wavelength and an objective lens. A phase plate for providing a phase difference to a beam incident on the polarizing beam splitter is provided between the polarizing beam splitter and the light sources. A portion of the laser beam incident on the polarizing beam splitter is reflected by the polarizing beam splitter and caused to be incident on a photo-detecting unit, so as to prevent an unnecessary portion of the laser beam is incident on the photo-detecting unit. According to the invention, the laser beam is used efficiently and the cost of fabricating an optical disk apparatus is reduced by eliminating a need for a gain controlling circuit in the photo-detecting unit.

摘要： In a synchronization system adopted in a synchronous-multisystem control apparatus comprising a plurality of systems operating synchronously with each other at a fixed control period, the synchronous-multisystem control apparatus can be operated in a single-system mode in the event of failures occurring simultaneously in some of the systems.The synchronous-multisystem control apparatus employs a plurality of control circuits each provided for one of the systems. Any particular one of the control circuits comprises: a period-signal generating circuit for generating a period signal indicating a start point of a control period; a synchronization-reference selecting circuit for outputting a synchronization-reference signal by referring to period signals generated by the systems; and a control-period correcting circuit for correcting a control period of the particular system by forming a judgment on a synchronization shift of the period signal generated by the particular system from the synchronization-reference signal and keeping the control period as it is in case the synchronization-reference signal is not generated.
