Abstract
A rotary magnetic head apparatus is provided which can be formed into a small size even if a plurality of reproduction heads are provided. The rotary magnetic head apparatus includes a rotary drum having a rotor of a transmission apparatus and a plurality of reproduction heads, a fixed drum having a stator of the transmission apparatus and a plurality of reproduction heads, a reproduction signal selection device for selecting a reproduction signal of an information recording medium, which signal is obtained by each of the reproduction heads and for arranging the reproduction signal in sequence, a rotor reproduction signal wiring section which is disposed in the rotor and to which is supplied the reproduction signal of each of the reproduction heads, which reproduction signal is sent from the reproduction signal selection device, and a stator reproduction signal wiring section, which is disposed in the stator, for receiving the reproduction signal from the rotor reproduction signal wiring section without contact.
