摘要： A rotary-head PCM data recorder in which PCM signals of m in number, a synchronizing signal, control signals related to the PCM signals, and a parity signal for error detection and correction are formed into data blocks, and data blocks of n in number are recorded on one track of a magnetic tape. Among the control signals, bits of signals common to n data blocks (i.e., information needed once for each track) are formed in distributed data allocated in a group of consecutive blocks or tracks, and multiple block distributive control data are recorded on one track multiple number of times, or multiple track distributive control data are recorded along n block strings a multiple number of times. In reproduction, block or track distributive data are composed to reproduce the control signals. The recorder thus arranged reduces the bit number needed for the control signals and compensates dropout of reproduced data due to scratches on the tape and the like.

摘要： A digital signal recording/reproducing apparatus capable of recording and reproducing digital signals having differences in respect to sampling frequency thereof and the number of quantization bits per sample by means of a common circuit arrangement includes means for varying revolution speed of rotating heads for recording and reproduction or traveling speed of a recording medium as a function of different sampling frequencies. A signal processing circuit for processing the digital signals so as to be suited for the recording on the recording medium is controlled by a clock signal of which frequency is changed in dependence on the different sampling frequencies. The signal processing circuit is arranged so that PCM data contained in a frame is constituted by a number of bits which is equal to a common multiple of the different quantization bit numbers and added with a common frame synchronizing signal and common error detection and correction codes to thereby prepare the PCM signal of the frame arrangement. The digital signals which differ in the sampling frequency and the quantization bit numbers can be recorded by same recording and reproducing apparatus with an improved efficiency with a same wavelength and in a same signal format.

摘要： In a rotary head type digital information signal recording and reproducing apparatus having plural rotary heads mounted on a rotary drum so as to be capable of recording and reproducing signals on parallel, oblique tracks on a magnetic tape, a tracking signal is recorded on at least one portion of each track which is not overlapped with a portion of each track where a digital information signal is recorded to avoid interference between the tracking signal and information signal. The tape travel speed and the rotary drum rotation speed are changed depending upon the transmission rate for a digital information signal to be recorded and reproduced to make the wavelength of a recorded signal frequency constant irrespective of the signal transmission rate. Tracking control is enhanced without increasing the error rate.

摘要： A method for fabricating a rear core for the magnetic circuit of a Hall effect magnetic head is disclosed. The bottom size of the rear core protrusion is made substantially equal to the size of a Hall element. A gap is provided between the Hall element and the rear core. In order to minimize the gap, the rear core block is provided with supports for fabrication, whereby the gap between the Hall element and the bottom protrusion of the rear core is positioned accurately. The supports are removed at the end of fabrication. The bottom protrusion of the rear core prevented pressure from being applied to the Hall element, thus improving the sensitivity of the Hall effect magnetic head without increasing noises.

摘要： An apparatus and method for recording on and reproducing from a magnetic tape a digital signal by rotating heads. A synchronizing signal, a control signal, and an error correction code are added to the digital signal, and the digital signal with those signals added is converted into a block form. At the recording time, a recording signal produced from a recording circuit is recorded on the recording medium by a first head of the rotating heads, and at the same time the recorded signal is reproduced by a second head of the rotating heads. In addition, there are provided a first recording mode in which two error correction codes are added, and a second recording mode in which three error correction codes are added. Thus, the recorded signal can be confirmed by the simultaneous playback made at the recording time so that the reliability in data can be assured.

摘要： A digital video tape recorder ("VTR") that selects data useful for generating images during trick playback operation and records the data in trick play tape segments arranged on a tape to form fast scan tracks and multi-speed playback tracks. Each fast scan track comprises trick play tape segments located on a diagonal, relative to the length of the tape, of the same angle as the angle at which the heads of a VTR are expected to pass over the tape during trick play operation at a specific speed and direction of operation. Each multi-speed playback track comprises a plurality of trick play tape segments arranged parallel to the length of the tape. Data which is used for at least one mode of trick play operation is recorded in each trick play tape segment. Each fast scan track and multi-speed track crosses multiple normal play tracks. During playback at a wide variety of speeds and directions, the heads pass over enough trick play segments of the multi-speed playback track to generate recognizable images during trick play operation. Data is recorded in each trick play segment in a manner that optimizes the amount of data that can be routinely recovered during trick playback operation despite tracking errors.

摘要： Methods of operating a digital video recording and playback device to identify trick play data, e.g., data that is intended for use during trick play modes of video playback device operation such as fast forward and reverse, by recording headers containing specific trick play information along with the trick play data are described. In one embodiment, the recording of headers which identify data as data intended for use during trick play as opposed to normal play operation is described. In addition to identifying data recorded data as normal play or trick play data headers associated with recorded data may identify the speed and direction of video tape recorder operation during which the specific data associated with the header is intended to be displayed at. When a data block includes data packets, a header may be used to identify various ones of the data packets as being for use during one mode of trick play operation, e.g., a first fast forward speed of operation, and other packets in the same data block as being for use during a second mode of trick play operation.
