PURPOSE:To reduce the slide noise easily and surely by sticking a vibrationproof alloy to part of a hole for coil winding of a magnetic head chip of a rotary head. CONSTITUTION:In a rotary head 10, two magnetic head chips 12 and 12 are mounted on a cylindrical rotary cylinder 11. These magnetic head chips 12 and 12 consist of a single crystal ferrite, and coils 15 are wound through winding windows 12a in approximate centers, and these head chips are fixed to chip bases 13 and 13, and chip bases 13 and 13 are attached to the rotary cylinder 11 by screws 14 and 14. A vibrationproof alloy 16 is packed and stuck to one end near the tape sliding face of the winding window 12a for coil winding formed in the magnetic head chip 12. Thus, the slide noise is reduced easily and surely with the simple constitution. |
