装置。[Claims for Utility Model Registration] (1) In a magnetic recording/reproducing device comprising a rotating cylinder that has a plurality of rotating magnetic heads and rotates relative to a fixed part, the magnetic head is located on the side of the rotating cylinder. A first reflecting mirror and a first prism are provided at positions passing through the rotation center line of the electric-to-optical converter and the rotating cylinder, and the converted light is converted into different specific wavelengths.
A reflecting mirror and a first prism take out a single multiplexed beam that coincides with the center line of rotation, and a second prism and a second reflecting mirror provided on the fixed part side separate it into the original multiple beams, which are then fixed. A signal transmission device for a rotating head, characterized in that an optical-to-electrical converter provided on the side outputs an electrical signal. (2) In a magnetic recording/reproducing device comprising a plurality of rotating magnetic heads and a rotary cylinder that rotates relative to a fixed part, an electric wire is installed in the fixed part to convert a signal into light of a specific wavelength. The light converter and the first
A reflecting mirror and a first prism are provided, and the converted light is taken out as a single multiplexed light coincident with the rotation center line of the rotating cylinder by the first reflecting mirror and the first prism. A second prism and a second reflecting mirror provided on a rotating cylinder separate the light into a plurality of original lights, and an electrical signal is given to the magnetic head via an optical-to-electrical converter provided on the rotating cylinder. A signal transmission device for a rotating head.
