Patent number: 5224081Abstract: A search operation control apparatus in an optical disc reader searches a desired position on an optical disc which is controllably rotated at a constant linear velocity and has its information pits arranged in a segmental spiral, in response to a search command which includes information of the desired position. The apparatus has an optical pickup, an optical-pickup moving controller, and an optical-disc driving controller. The optical-pickup moving controller controllably moves the optical pickup from a current position to a desired position at high speed when it receives a search command. The optical-disc driving controller controllably drives the optical disc during an acceleration/deceleration control timing, and a free-run or constant-run time. During the high-speed translation of the optical pickup, spindle servocontrol to the optical disc is not executed, but the acceleration/deceleration control process and the free-run or constant-run control process are executed.Type: GrantFiled: July 30, 1991Date of Patent: June 29, 1993Assignee: Funai Electric Co., Ltd.Inventors: Masaru Muraoka, Yutaka Naka, Eiji Miyazaki

Patent number: 5222054Abstract: A seeking operation control apparatus in an optical disc reader reads track information stored in an optical disc with an optical pickup which is movable in the radial direction in order to seek a desired track. It includes a calculator for calculating track values, a jump driver, a jump controller, and a reading controller. The calculator calculates the number of tracks in the distance between the track onto which the optical pickup is positioned and a desired track based upon track information obtained by the optical pickup. The jump driver induces the optical pickup to jump one or more predetermined tracks. The jump controller controls the jump driver whereby it performs the track jump operation repeatedly as required to make the optical pickup jump the track value calculated by the calculator. The reading controller directs the optical pickup to read track information after the jump control operation is completed.Type: GrantFiled: September 17, 1991Date of Patent: June 22, 1993Assignee: Funai Electric Co., Ltd.Inventors: Masaru Muraoka, Syozo Takegawa
