Abstract
PURPOSE:To perform fine slow motion by attaching 4 rotary magnetic heads and reproducing signals of one field plural times successively to obtain a slow motion image. CONSTITUTION:Video signals of one field are recorded successively as a recording trace inclined to the longitudinal direction of a magnetic tape by using the 1st and 2nd rotary magnetic heads A, B whose azimuth angles are different each other. In this case, the 3rd rotary magnetic head A' with the same azimuth angle as the head B is arranged near the head A and the 4th rotary magnetic head B' with the same azimuth angle as the head A is arranged near the head B. At the time of slow motion reproduction, the magnetic tape is driven intermittently in every 1 pitch of recording trace and the heads A, B, A', and B' are used selectively, performing fine slow motion reproduction.
