Claims

[Scope of utility model registration request]

A spindle mechanism having a rotary shaft that is rotationally driven, a medium rotated by the spindle mechanism, an actuator mechanism having a rotary shaft to which a magnetic head for recording and reproducing information on the medium is fixed, and an actuator mechanism that rotates the rotary shaft. 5. A magnetic disk device comprising a voice coil motor to be moved, and a cover removably fixed to a frame, the spindle mechanism, the medium, and the actuator mechanism being housed in the cover and shielded from outside air. The rotating shaft is cantilever-supported by the frame, the rotating shaft is supported at both ends by the frame and a top arm fixed to the frame, and the voice coil motor is supported by the rotating shaft. 1. A magnetic disk drive, characterized in that the voice coil motor and the rotation shaft are provided with a separable coupling portion that is installed coaxially with the rotation shaft.
