Abstract
PURPOSE:Not only to obtain a rotary magnetic head which is small-sized and has high accuracy, but also to simplify its assembling, and to realize its mass production, by forming a magnetic head itself in one body as a part of a rotary plate, and also making this magnetic head body directly provide with a rotation center position control function. CONSTITUTION:The first and second semi-circular core half bodies 11, 12 consisting of a magnetic substance plate make a pair by forming a semi-circle straight line part being its chord as a butt surface, are butted and junctioned at a prescribed interval G, and are formed in one body. This junction is executed by use of an adhesive material of a glass compound. On the core half bodies 11, 12, grooves 13, 14 and 15 for a winding are provided, windings 16, 17 are wound, and 2 magnetic head parts opposed at 180 deg. are formd. At a position being at an equal distance from both end head surfaces of the butt junction surface of the first and second core half bodies 11, 12, a rotation center position controlling groove 21 for press-contacting with a rotation center shaft 20 and controlling its rotation center position is provided. This position controlling groove 21 consists of a triangular groove 22 provided on the first core half body 11, and a semicircular groove 23 which is provided on the second core half body 12, makes the rotation shaft 20 insert through, and has secured its escape.
