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： Methods and systems are provided for dubbing a digital video signal on a record medium wherein the digital video signal includes variable-length codes arranged in a fixed-length word format. The variable-length codes are separated from the fixed-length word format data. Error codes indicating errors in the separated variable-length codes are provided. The separated variable-length codes together with the error codes are formed into new data blocks having a fixed-length word format and the new data blocks are recorded on a record medium.

摘要： In a digital video tape recording and/or reproducing apparatus including a pair of rotary magnetic heads having a predetermined head width and gaps with mutually different azimuth angles which helically scan a magnetic tape as the tape is advanced in order to reproduce digital video signals that have been previously azimuth-recorded in oblique tracks on the tape, there is a tape transport that can transport the tape either at a standard speed or at a non-standard speed. If the tracks recorded on the video tape have a track width equal to the head width, then the tape is transported for reproduction at the standard speed, whereas, if the track width is different from the head width, the tape is transported at the non-standard speed. For example, if the track width is twice the head width, then the tape is transported at twice the standard speed. On the other hand, in another embodiment, when the track width is half of the head width, the tape is transported at a non-standard speed that is one-half the standard speed.

摘要： A digital signal processing apparatus adapted for use in a digital video tape recorder or the like. The apparatus includes a digital multiplexer for combing an input digital information signal and an input digital pilot signal with each other on a predetermined time basis so as to produce a composite recording signal; and a variable gain amplifier supplied with the composite recording signal of the digital multiplexer for amplifying at least one of the digital information signal and the digital pilot signal in the composite recording signal to respective different levels. With a relatively simple circuit configuration and a control action which operates in a relatively straight-forward manner, a relatively high operational reliability is achieved.

摘要： Apparatus for regenerating a coded digital signal, comprising an interference cancellation equalizer for cancelling an interference component from an input digital signal and a decoder. The equalizer includes a compensator for high frequency compensating the input digital signal, an extractor for extracting intercode interference from the compensated digital signal, and a subtracter for subtracting the extracted intercode interference from the input digital signal to produce a waveform equalized signal. The decoder recovers the original digital signal as a function of the correlation or samples of the waveform equalized signal.

摘要： Data reproducing apparatus for reproducing data that is recorded with a selected one of at least two different recording densities such that the played back data may exhibit different frequency characteristics, depending upon the recording density. The played back data is supplied to a selected one of plural equalizer circuits whose respective equalizing characteristics match the frequency characteristics of the played back data, thereby reducing the bit error rate of the played back data, regardless of the particular recording density with which that data had been recorded.

摘要： In a digital data reproducing apparatus for demodulating digital data recorded on a magnetic medium with either a first or second record modulation mode, such mode is detected by identifying the frequency of a recovered clock signal derived from the digital data by a clock recovery circuit, and an appropriate demodulation circuit for the recording mode is then selected to demodulate the reproduced digital data.
