Abstract:
A rotary magnetic head apparatus which reproduces a signal of a plurality of recording tracks recorded on a tape-like information recording medium by using a plurality of reproduction heads without depending on the arrangement of the recording tracks in the information recording medium, said rotary magnetic head apparatus comprising:a transmission apparatus for transmitting power and signals between a rotor and a stator in a non-contact manner; 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; reproduction signal selection means for selecting a reproduction signal from each reproduction head and arranging the reproduction signal from each reproduction head in sequence; a rotor reproduction signal wiring section which is disposed in the rotor and to which a reproduction signal of each reproduction head is provided, which reproduction signal is transmitted from the reproduction signal selection means; and a stator reproduction signal wiring section, disposed in the stator, for receiving a reproduction signal in a non-contact manner from the rotor reproduction signal wiring section, wherein said rotary magnetic head apparatus is enabled to perform a reproduction operation utilizing a non-tracking procedure.
