Seek control system for optical storage apparatus |
摘要 |
A seek control system used in an optical storage apparatus to move an optical head, which at least reads information from an optical disk by applying light thereto, to a target position on the optical disk. The seek control system includes a positioner for moving the optical head for seek, and a one-dimensional optical position detector having a photo-sensitive surface disposed in the path of movement of the optical head to output a position signal corresponding to a light spot position on the photo-sensitive surface. The seek control system further includes a light-emitting device provided on either the optical head or the positioner to apply light to the one-dimensional optical position detector, and a controller for controlling the drive of the positioner on the basis of a position detection output of the one-dimensional optical position detector.
