Device for recovering video information from magnetic tape

摘要

A device for recovering video information from magnetic tape, which comprises a magnetic head assembly arranged within a current-carrying casing in a manner allowing rotation of the magnetic heads with a hollow shaft. The magnetic heads are electrically coupled to the winding of a slip-ring rotor. A closed three-dimensional coupling turn couples the rotor winding to the winding of a slip-ring stator. The stator winding is electrically coupled to a reproduction amplifier through a step-up transformer and a first reproduction signal correcting circuit. The output of the reproduction amplifier is connected to a second reproduction signal correcting circuit inductively coupled to a short-circuited turn which is partly arranged within the current-carrying casing. The short-circuited turn has a lower inductance as compared to the closed three-dimensional coupling turn.
