摘要： A multichannel recorder, such as for color video, reduces the width of recording heads that record low frequencies, and interchanges the order of one such head with a high frequency head. This both reduces crosstalk and keeps interchannel time displacement low.

The video tape recorder of the invention comprises a recording system and a playback system. The recording system includes a recording processing unit for converting the plurality of video signals into recordable signals, respectively; first and second rotary head pairs which are oppositely arranged with respect to a cylinder. Each head has a track width narrower than a recording track pitch and have gap azimuth angles in an opposite relation. Each head records the signals onto the tape and reads out the signals from the tape. The recording system further includes a unit for recording a control signal synchronous with a vertical sync signal included in one video signal onto a control track. The playback system includes a playback processing unit for reconstructing reproduced signals from the rotary head pairs into video signals and a servo unit for reproducing the control signal to control the rotary head pair and the tape run.

摘要： A video signal recording/reproducing apparatus with two groups of rotary heads which respectively include one main head and two auxiliary heads is set forth. The apparatus includes a head switching device for switching one of the two auxiliary heads into operation according to input video signals and a tape speed switching device for switching the running speed of a video tape according to the input video signals. The apparatus permits the video signal recording/reproducing of both video signals having a wide band and a narrow band. The apparatus also defines an effective tape wrap angle wherein the position of head switching is removed from a screen so that the division of images within the screen is avoidable and so that noise bars produced in the boarders of these images do not appear even in the case of special reproduction. The apparatus further permits recording of video signals on a video tape while approximately conforming a line number in the center of the main tracks to that in the center of the effective lines of the TV image. Accordingly, noise bars produced by head switching and image parts with less information amount can be removed by separating and locating them out of the upper and lower ends of the screen.

摘要： A magnetic recording and reproducing apparatus capable of recording video, audio and other information on a magnetic tape by, for example, the helical scanning method. A rotary head is rotated at an m-fold speed to record intermittent tracks on the magnetic tape so that real-time simultaneous monitoring is performed. By high-speed dubbing due to high-density intermittent recording and by increasing the number of repetition of track scanning, the information is recorded and reproduced simultaneously with a plurality of channels. Any tracking error is detected to form a continuous and uniform track pattern. With this intermittent comb-shaped recording, reciprocating recording and reproducing can be realized.

摘要： In one aspect of the present disclosure, the degree of side erasure occurring in neighboring tracks is controlled by controlling the skew angle of the tape head, relative to the longitudinal direction of motion of the tape past the head as a track is written. In one embodiment, the tape head is rotated relative to the longitudinal direction of tape travel, and the trailing edge of the tape head which forms an acute angle with the edge of a track being written, is used for writing tracks at a desired track pitch. Other aspects and advantages may be provided, depending upon the particular application.

摘要： A magnetic recording/reproducing device for recording/reproducing information signals for one recording unit over a plurality of recording tracks by helically scanning a magnetic tape with rotary heads. The information signals for one recording unit are recorded on the plurality of recording tracks on the magnetic tape, and guard bands are formed simultaneously between the one recording units. The recording density is substantially improved. Erase heads overwrite the information signals on the magnetic tape and the plurality of recording tracks for one recording unit on the magnetic tape are erased en block, which prevents over-erasing unerased portions during editing.
