摘要： It is desirable to greatly reduce the disturbance that arises in a focusing error signal by a astigmatic detection method and offset that arises in the tracking error signal by a push-pull method when reproducing various information storing disks, such as a DVD-RAM disk. It is also desirable to provide an optical disk apparatus which is able to reproduce a variety of high density optical disks, such as DVD-RAM and DVD-ROM disks, as well as conventional disks, such as CD, CD-ROM, CD-R disks, by using a simple optional head. For this purpose, an optical disk apparatus irradiates three optical beams produced by a diffraction grating on the specified position of an optical disk and detects reflected light using a specified optical detector divided into twelve parts.

A footrest system is provided with: a reclining device that rotates an upper end part side of a seatback in the direction of arrow A and holds it at a predetermined angle of rotation; and a slide device that slides a front seat in the direction of arrow B with respect to a vehicle body floor. When an occupant seated in a rear seat uses a footrest portion of the seatback, the reclining device is operated and the upper end part side of the seatback is inclined toward the vehicle front side. Further, the slide device is operated and a slide portion of a seat cushion is moved in a vehicle front-rear direction along a rail portion.
