摘要： A record disc producing apparatus, which can be used for searching a desired track location rapidly, includes a pick-up device (11) for reading data from the disc and movable in a radial direction with respect to the disc and a driver (16) for driving the pick-up device (11) radially with respect to the disc. The moving velocity of the pick-up device (11) is detected and used to produce a velocity signal corresponding to the moving velocity. A kick signal is generated to energize the driver (16). The kick signal is controlled so that the velocity signal approaches a predetermined value.

摘要： A small amplitude, low frequency, signal is added to the focus servo signal controlling the position of the objective lens of an optical disc storage system after focus acquisition has been achieved, so as to produce a slight defocusing effect of the light spot on the disc. The resulting variations in the back signal is utilized by a synchronous detection circuit scheme to extract magnitude and polarity information of the focus offset present. That information is fed back to the focus servo signal to null out the focus offset, thereby assuring continual accurate focusing of the laser beam even under conditions of changes in the mechanical alignment of the optics of the storage system and/or the d.c. stability of the electronics of the storage system.

摘要： A counter for counting marks, e.g. data tracks on a recording support. Counter pulses are sent to a forward-backward counter to count marks over which a scanner passes, e.g. the data tracks of an optical recording device scanned by a light beam. Depending on the direction of movement of the scanner, a directional logic determines the counting direction of the forward-backward counter. To avoid errors during track counting, attention must be paid to the phase relationship of the counting pulses and the output signal of the directional logic. In order to be able to count the number of marks or tracks scanned independently of the phase relationship of the counting pulses and the output signal of the directional logic (RL), the counting pulses (ZI) are taken to a first counter (Z1) when the scanner or the light beam crosses the marks or tracks in the desired direction; however, the counting pulses (ZI) are applied to the counter input (V) of a second counter (Z2) when the scanner crosses the marks in the undesired direction. To jump over m marks, the first counter (Z1) is set to a first predetermined value while the second (Z2) is set to a second predetermined value. When the counter readings coincide, the scanner or light beam is stopped. Counting devices for counting marks or data tracks which are mechanically or contactlessly scanned, e.g. in CD players, video disc players, DRAW disc players or magneto-optical recording and/or playback devices.

摘要： At the conclusion of a track seek operation, handoff to track following servo control is delayed for a short time period during which the drive microprocessor (30) determines if the head (10) has failed to stop at the target track by sensing the occurrence of a predetermined number of track crossing pulses, the detection of which causes iterative generation and application of braking current pulses to the head actuator motor (11). The amplitude and duration of each braking current pulse is chosen to cause forward motion of the head (10) to be retarded to a predetermined percent of its pre-existing velocity. The microprocessor routine includes provision for iteratively determining when the head (10) has slowed to a velocity which allows the track following servo (16) to acquire control of the head (10).

摘要： An apparatus for controlling the tracking of an optical pickup is equipped with a position sensor (21a) which detects the displacement of a tracking actuator. As a signal produced by the position sensor (21a) exceeds a predetermined value, a feeding mechanism (22) is intermittently driven to feed the optical pickup (20). While the feeding mechanism (22) is being driven, furthermore, the feedback control is effected so that the mechanism (22) is smoothly moved and the tracking servo consumes reduced amounts of electric power. This enables the drive motor to be constructed in a small size.

摘要： When helical or concentric pit lines (p) are formed on an optical disk original (3) by irradiating a laser beam to the original (3), the laser beam is applied along path which is in parallel with, or diagonally to, the bit lines (p). For example, the laser beam is applied in such a manner as to describe an arcuate path which is in touch with the innermost pit line {p (point B)} and the outermost pit line {p (point A)} in the optical disk original (3), and uses as its diameter the sum of the radius r of the innermost pit line and the radius R of the outermost pit line.
