Abstract
A device for providing rotary electric coupling for a recorder/reader of magnetic tape including at least one magnetic head (21, 22) which is rotated at the periphery of an equatorial slot in a cylindrical drum over which the helically wound tape is caused to run. Said device is intended to transmit electrical signals representative of information recorded on or read from said tape, between a rotor-forming rotating portion connected to the head and a stator-forming stationary portion connected to electronic means respectively for emitting and/or receiving said information. The device further includes a two-plate capacitor (29, 42) for each of its heads (21, 22), said capacitor plates being disposed facing each other in pairs and one plate in each pair being fixed to the rotor and the other to the stator.
