求の範囲第１項に記載の回転磁気ヘッドの駆動装置。[Claims for Utility Model Registration] ■ In a drive device that drives a rotating magnetic head by a power source provided outside the guide cylinder, a driving rotating part that is directly connected to external power and rotationally driven, and a magnetic head. A driven rotating part that supports and is freely rotatable is disposed coaxially and close to each other, and the driving rotating part engages only when the driving rotating part rotates in one predetermined direction with respect to the driven rotating part. What is claimed is: 1. A drive device for a rotating magnetic head, characterized in that a one-way clutch is interposed which causes both rotating parts to integrally rotate and disengages when the driving rotating part rotates in the opposite direction. ■ A one-way clutch has a cam surface whose distance from the center gradually increases on one of the facing surfaces of both rotating parts, and a cylindrical surface facing the cam surface on the other rotating part. A wedge-shaped space is formed between the cam surface and the cylindrical surface, and a rolling element is interposed in the wedge-shaped space, and only when the driving rotating part rotates relative to the driven rotating part in one direction, The driving device for a rotating magnetic head according to claim 1, wherein the rolling element is wedged between the cam surface and its opposing surface, and the two rotating elements are rotated as one unit.
