摘要： A control system for a helical scan video tape recorder having two scanning heads each of which employs a bimorph plate to dynamically control the tracking path of its respective head chip, produces separate dynamic control signals for each of its two heads by "wobbling" or "dithering" the heads with respect to their scanning paths and employing resulting amplitude variations in the reproduced signals to drive the mean paths of the head chips into coincidence with the recorded tracks being scanned. A transfer circuit transfers a portion of an offset voltage, representing a final control signal existing at the end of scanning of a recorded track by one of the heads to the control system controlling the other head. This tends to bias the second head in the same direction in which the first head is biased in order to avoid the two heads scanning different tracks during still or slow motion reproduction.

摘要： A magnetic head assembly for a video tape recorder includes a piezo-electric support, preferably constituted by a bi-morph leaf or leaves, supported at one end, for example, on a rotary portion of a tape guide drum, and a magnetic head mounted at the other end of the piezo-electric support, and the piezo-electric support has two pairs of first and second electrodes secured on opposed major surfaces, respectively, of the support and extending in the direction between the ends of the support, that is, in the lengthwise direction of the latter, with such pairs of electrodes being parallel and spaced from each other in the direction across the support. Thus, by applying suitable control voltages between the first and second electrodes of the two pairs thereof, the piezo-electric support can be made to flex or bend longitudinally and/or torsionally, for example, for correcting tracking erros and/or for varying the azimuth angle, respectively, of the mounted head.

摘要： A tracking-error correcting system for use in apparatus of the type wherein signal information is recorded in parallel tracks on a record medium. The correcting system is useful for correcting deviations between the scanning path of a transducer which scans the record medium and the parallel tracks. A ramp signal generator generates a periodic ramp signal of substantially constant amplitude and having a duration which is equal to at least a portion of the time required for the transducer to traverse its scanning path. The level of the ramp signal is changed for successive scans of the record medium. An adjustable transducer support is provided to support the transducer in scanning relation to the record medium and is operative to displace the transducer transversely with respect to a parallel track in response to a drive signal applied thereto so as to align the scanning path of the transducer coincidentally with the parallel track. The ramp signal of changing level is used to produce the drive signal. The level of the ramp signal no longer is changed when the scanning path of the transducer is detected to substantially coincide with a parallel track.

摘要： A hydraulic transmission (21) has an electric actuator (86) for changing its output/input rotation speed ratio. A controller (90) of the actuator memorizes a command current value to the actuator supposing that load is not applied on the hydraulic transmission, and calculates a value of load applied on the hydraulic transmission by calculating a difference between an actual command current value to the actuator and the memorized command current value. A command current value is compensated based on the value of load, and the actuator receives feedback to be controlled. A vehicle may have a differential mechanism (10), which combines rotation powers on input side and output side of the hydraulic transmission. A detector (82) detects rotation speed of a main speed change output shaft (27) serving as an output shaft of the differential mechanism. If the detected rotation speed differs from target rotation speed of the shaft (27) determined based on operation of a speed change operation tool, the actuator is forcedly controlled. This difference is supposed to be caused by load applied on the hydraulic transmission, whereby the load is calculated.

摘要： Rotary head recording and/or reproducing apparatus in which respective oblique tracks on a record medium are scanned, each track having an information signal area in which information data is recorded and a track following area in which a tracking control pilot signal is recorded. The track following area precedes the information signal area; and in the preferred embodiment, an additional track following area follows the information signal area. The pilot signal is recorded in only a portion of the track following area, the remainder of which has timing sync data recorded therein. In an after-recording mode the timing sync data is reproduced, detected and used as a reference to define an after-record area.

摘要： An apparatus and method for reproducing and after-recording digital signals in slant recording tracks sequentially arranged on a recording medium includes a recording subsystem for recording digital signals in each of the slant tracks and a reproducing subsystem for reproducing digital signals therefrom. The recording and reproducing subsystems include one or more recording and/or reproducing heads for scanning each of the tracks for recording and reproducing digital data therein. A tracking control subsystem controls tracking of the heads with respect to the tracks in a reproducing mode based upon tracking signals recorded both in first and second tracking signal recording areas of the tracks located at initial and final scan positions, respectively, of each track. In an after-recording mode, the tracking control subsystem utilizes tracking signals recorded in only one of the tracking signal recording areas while recording digital signals in a first sub information recording area proximal to the area from which the utilized tracking signals have been obtained.
