Abstract:
A rotary magnetic head apparatus which records a signal onto a tape-like information recording medium and reproduces a signal of a tape-like information recording medium, said rotary magnetic head apparatus comprising:a transmission apparatus for transmitting power and signals in a non-contact manner between a rotor and a stator; a rotary drum having the rotor of the transmission apparatus, a recording head and a number of reproduction heads; a fixed drum of the rotary magnetic head apparatus having the stator of the transmission apparatus; reproduction signal selection means for selecting a reproduction signal of the information recording medium, which reproduction signal is obtained by each reproduction head and for arranging the reproduction signal in sequence; a rotor reproduction signal wiring section which is disposed in the rotor and to which is input a reproduction signal of each reproduction head, which reproduction signal is sent, from the reproduction signal selection means; a rotor power-supply wiring section disposed in the rotor; a number of rotor recording signal wiring sections each only disposed between the rotor reproduction signal wiring section and the rotor power-supply wiring section; a stator reproduction signal wiring section, which is disposed in the stator, for receiving a reproduction signal in a non-contact manner from the rotor reproduction signal wiring section; a stator power-supply wiring section disposed in the stator; and a number of stator recording signal wiring sections each only disposed between the stator reproduction signal wiring section and the stator power-supply wiring section, wherein power is supplied from the stator power supply wiring section through the rotor power supply wiring section to the number of reproducing heads during a reproduction operation and power is not supplied from the stator power supply wiring section through the rotor power supply wiring section the number of reproducing heads during a recording operation when the recording head is recording a signal.
