摘要： A digital signal recording and reproducing apparatus are disclosed which can record digital data of the advanced television (ATV) system or some other digital data onto a recording medium without the necessity of displacing recording areas for sub codes of the recording medium and can thus make effective use of the recording capacity of the recording medium. When an ordinary television signal is to be recorded, the length of the Inter Block Gap IBG and amble areas between an audio signal recording area and a video signal recording area is set to an integral number of times the length of a synchronizing block of a digital audio signal and a digital video signal. When data of the ATV system or like data are to be recorded, the data are recorded continuously from the audio signal recording area to the video signal recording area.

摘要： Methods and apparatus are provided for recording video signals in a plurality of tracks on a recording medium. In certain embodiments, first and second video signal intervals include respective first and second common sub-area signals representing at least one common sub-area of a video screen. The common sub-area signals of the first and second video signal intervals are recorded at respectively different locations within the plurality of tracks. In certain embodiments, component color video signals including luminance signals and first and second color difference signals are divided into a plurality of discrete cosine transformation (DCT) blocks and blocks representing common respective subdivisions of a video screen are assembled into corresponding macro blocks. Adjacent macro blocks are assembled into super macro blocks which, in turn, are arranged in a shuffled sequence relative to the positions of their subdivisions on the video screen for recording in the shuffled sequence. In certain embodiments, digital video signals representing a video screen are recorded in a plurality of tracks on a recording medium after dividing the digital video signals into a plurality of macro blocks assembled into sub-area groups of the video screen. The sub-area groups are shuffled by forming a sequence of track units each including a plurality of the sub-area groups one each from a respective horizontal division of the video screen. Each track unit is recorded in a respective one of a plurality tracks on the recording medium.

摘要： Video and audio data are recorded onto video and audio signal recording areas of a track of a record medium, these areas being included either in one of several segments in the track or the track being comprised of only a single segment of video and audio signal recording areas. Audio data that is supplied at substantially the same time as the video data is compressed and recorded in a first audio sector of the audio signal recording area. Then, depending upon whether a first or second audio signal recording mode is selected, either compressed audio data which is derived from the audio data supplied at substantially the same time as the video data or independent compressed audio data is provided. The derived or independent compressed audio data is recorded in a second audio sector of the audio signal recording area.

摘要： Methods and apparatus are provided for recording and reproducing digital information signals including image and audio portions in successive tracks on a magnetic tape. An ID signal is produced for one of an image portion and an audio portion of a corresponding digital information signal to be recorded. The ID signal indicates whether the portion is to be after-recorded in a respective track. The ID signal is combined with the portion to form a recording signal. Previously recorded digital information signals are reproduced from the track and an ID signal thereof is obtained. The recording of the portion in the track is controlled based on the reproduced ID signal.

摘要： A digital video tape recorder includes a rotary drum that has a leading head and a trailing head mounted thereon for recording video signals in respective slant tracks scanned on the tape while the tape is advanced. Each of the tracks includes, in sequence in the scanning direction of the respective head, a first auxiliary recording area, a second auxiliary recording area and a video signal recording area. The heads are displaced with respect to each other on the drum in the scanning direction by a distance that is less than the distance in the scanning direction between an ending edge of the first auxiliary recording area of the track formed by the trailing head and a starting edge of the video recording area of the track formed by the leading head. Because of the arrangement of the heads, after-recording of audio signals in the first auxiliary recording area by the trailing head is completed before the leading head begins reproduction of video signals. This prevents cross-talk from the audio recording signal that would disrupt the reproduced video signal. A satisfactory picture can therefore be reproduced during after-recording of audio signals.

摘要： An automatic head scan tracking system for a video tape player includes a bi-morph leaf mounting a magnetic head on a drum rotatable for scanning the head across a magnetic tape having video signals recorded thereon in successive parallel tracks, the bi-morph leaf mounting the head for movement by a deflection signal applied thereto in either direction transverse to the direction of scan of the head across the tape, a generator of a sawtooth signal having a predetermined slope which, when applied to the bi-morph leaf, deflects the latter to cause the direction of the head scan across the tape to coincide with the direction of the recorded track, a circuit for producing timing signals indicating the rotational position of the magnetic head with respect to the beginning of a scan of the tape, and a circuit responsive to the timing signals and associated with the sawtooth signal generator for adjusting the starting point of the predetermined slope of the sawtooth signal so as to occur sufficiently in advance of the beginning of a scan of the tape by the magnetic head for dissipating any transient vibrations of the bi-morph leaf prior to the commencement of the scan.

摘要： A method and apparatus for correcting tracking errors of a transducer which scans successive, parallel, adjacent record tracks of a record medium so as to reproduce information signals therefrom. The information signals, which may comprise video signals, are recorded in the parallel record tracks, and predetermined signals also are recorded at predetermined locations in the information signals. When the information and predetermined signals are played back, at least one cross-talk predetermined signal which is recorded in at least one adjacent track also is played back. The cross-talk predetermined signal is detected and a control signal is produced in response to the level of the detected cross-talk predetermined signal. The position of the transducer with respect to the track being scanned thereby is adjusted in accordance with the control signal. In one embodiment, the control signal is recorded at a predetermined location in each horizontal blanking interval of the video signals; and the horizontal blanking intervals which are recorded in one track are displaced with respect to the horizontal blanking intervals which are recorded in the adjacent track. This displacement of the horizontal blanking intervals, and thus the predetermined signals, in adjacent tracks facilitates the detection of the cross-talk predetermined signals which, for example, may comprise pilot signals.

摘要： The mechanical lash adjuster is arranged between a cam and one end of the stem of a valve urged by a valve spring. The lash adjuster comprises an unrotatable housing having a thread, a plunger subjected to the force of the cam and formed with a thread in engagement with the thread of the housing, and a plunger spring urging the plunger against the action of the valve spring. The lead and flank angles of the engaging threads are set such that the engagement threads can slidably rotate under a given shaft load applied to the plunger unless the frictional torque TB, generated by the friction between the slidable frictional surface F2 of the plunger and a shaft load transmission member to act on the plunger, exceeds the thrust torque TF imparted by the shaft load to the plunger.
