  • Patent number: 5289449
    Abstract: A circuit for controlling the optical pickup position in an optical disc reproducing apparatus is constructed such that when the power is applied, a user recognizes the position of the pickup which is used to pickup information from a disc with information recorded on both sides, by recognizing whether the pickup is facing the upward side or downward side of the disc. The circuit further controls the pickup to be positioned on the innermost circumference of the reproducing side in the reproducing stop or ending operation. Therefore, the time needed to recognize which the first reproducing side for successive reproducing is decreased, while reducing power consumption needed to move the pickup in the reproducing stop operation.

  • Patent number: 5235575
    Abstract: An apparatus and method for successive reproducing in an optical disc recording/reproducing system, can perform the conventional successive reproducing function plus a successive reproducing function capable of generating a reproducing signal while transferring the pickup. For this special successive reproduction, the apparatus has a memory which outputs reproducing information of a second reproducing side which has been previously stored during the time period required for both transferring the pickup and skipping portions of the disc to prevent repeated reproduction, and key input unit including separate control keys for selecting normal successive reproduction and special successive reproduction or a single mode selecting key, so that the user can selectively reproduce disc information as desired. In the special successive reproducing mode, reproduction continues with an uninterrupted supply of the reproducing signal.
