Abstract
912,477. Scanning magnetic tapes; television. NIPPON VICTOR KABUSHIKI KAISHA. Sept. 27, 1961 [Oct. 12, 1960], No. 34762/61. Class 40 (2). To avoid picture-flicker when playing-back oblique video-frequency tracks on a magnetic tape due to tape weave or swinging of drummounted heads along paths such as in Fig. 5B, wide, overlapping tracks 6<SP>1</SP> are recorded covering the entire tape while play-back is by a narrower head scanning a constant-width portion of the recorded tracks. Separate record and play-back heads may be mounted on a common drum. During high-speed editing by increasing the linear speed of the tape such that the play-back head scans tracks such as X<SP>11</SP>, Fig. 7, the fullyrecorded tape provides a continuous output signal while the head skips the tracks.
