摘要： A reproducing apparatus reproduces information signals recorded multi-segmentally on oblique tracks on a tape. Track ID information recorded in the tracks is detected and compared with a reference frame to obtain a phase difference. The tape transportation is controlled in response to this phase difference to correct a reproduced phase so that it is made to coincide with a reference frame phase, as well as to perform tracking control using a tracking pilot signal recorded on the oblique track together with the information signal.

摘要： In an apparatus for multi-segment recording/reproducing of a compressed digital video signal, a reproduced position within a group unit of the video signal is detected by a reproduced position detector in its reproducing state. A relative position detector detects and stores a phase difference of the reproduced position and a position indicated by a reference signal synchronized with the input video signal. A delay time adjuster adjusts a delay time of the compressed video signal according to this phase difference. A head is changed over from its reproducing state to its recording state by a switch so as to record the compressed video signal delayed by the delay time adjuster on a recording medium.

摘要： An information reproducing apparatus for reproducing information recorded on slant information tracks includes magnetic heads mounted on a rotary cylinder. The magnetic heads scan a magnetic tape which has slant information tracks on which tracking pilot signals are formed. A tracking error detector detects the tracking error signal of the magnetic head scanning using the tracking pilot signal recorded on the slant information tracks. The tracking error detector then generates a tracking error signal indicating the amount of the track bending. A control signal generator generates a control signal in response to the tracking error signal for controlling the scanning position of the magnetic head. A tracking controller controls the slant track scanning position of the magnetic head.

摘要： A tape medium recording and/or reproducing apparatus suited for use in recording or reproducing information on or from a plurality of tracks on a tape medium. Each track has first and second regions defined therein in a direction conforming to the direction of scan. Each first region has a positioning signal recorded therein while a tracking pilot signal is recorded in selected ones of the first regions. The apparatus includes a positioning signal detector for detecting the positioning signal to provide a reproducing position signal, and a reproduction timing generator for generating a reproduction timing signal at a first timing determined by the reproducing position signal. A timing memory is provided to store the length of time from the timing, at which the rotational reference position of a cylinder has been detected, to the first timing. When no positioning signal can be detected, a timing protector generates a pseudo timing signal based on a previously detected timing stored in the timing memory and also for combining the pseudo timing signal with the reproduction timing signal to provide a protection timing signal. A tracking control section performs tracking control in reference to a level determined by the pilot signals sampled by the sample timing signal. The apparatus can perform insert-recording by determining the timing therefor based on the reproduction timing signal.

摘要： A tracking error detecting circuit in which tracking error detecting pilot signals having different frequencies are added to a main signal every track and recorded onto a magnetic recording medium, and upon reproduction, reproduction output levels of the pilot signals reproduced as crosstalks from both of adjacent tracks are compared, and a tracking error is detected. n signals having the same frequencies as those of the pilot signals and whose phases are different are generated and multiplied to the reproduction signal. Unnecessary components are eliminated by n LPFs (Lowpass filters). The amplitude values of the reproduced pilot signals are vector separated and detected. Further, the vector separated amplitude values are vector synthesized and detected. Therefore, by multiplying the signals having the same frequencies as those of the pilot signals, the synchronous detection is performed. The influence due to the undetected pilot phases is solved by detecting by performing the vector separation and synthesis. Therefore, the amplitude values can be certainly detected by the synchronous detection. The signal to noise ratio of the reproduction pilot signals can be determined by the LPFs (lowpass filters). Even in the case of a bad transmission signal to noise ratio of the reproduction pilot signals which could not be coped by the conventional construction, the amplitude values can be certainly detected.
