Magnetic head drum for recorder - has inductive signal transmission with built in supply generator

摘要

The video recorder head has a fixed drum (1) that has a transmitter (3) for signals. The windings (2) are coupled to the video processing circuitry. Mounted on the drum are stator windings (4) of the drive motor. The rotating drum (6) has two or more magnetic heads (K1,K2) and connects to the spindle (7). The drum carries the rotating elements (8) of the signal transmitter and this connects with active components (10). The rotor carries permanent magnets (14) as part of the drive motor. The voltage for the circuit is provided by a generator (17) built into the end of the unit. ADVANTAGE - Non contact signal transmission and built in power generation.
