    摘要: A turntable is a table mounted to a shaft (4) of a spindle motor and the turntable supports a laminated disc thereon and drives the disc in rotation. The laminated disc includes a lower disc and an upper disc stacked on the lower disc, and is supported on a disc-supporting surface. When the disc is loaded on the turntable, a fitting member fits into the center hole of the laminated disc for centering the laminated disc with respect to the shaft. The fitting member fits the center hole of the lower disc when the laminated disc is supported on said disc-supporting surface. The turntable may include a tapered member which guides the laminated disc to the disc-supporting surface. The laminated disc includes lower and upper discs each having an edge which defines the center hole. The corners of the edges are cut away along a circumference of the center hole. The upper and lower discs are placed together so that the cut-away corner directly face each other.

    摘要: A rotary magnetic head device has a plurality of bobbins to which coils are respectively fixedly attached, and a plate spring fixedly attached to the bobbins. The plate spring has a plurality of front ends to which magnetic heads are respectively fixed. The magnetic heads are held in such a manner that, when a current is selectively supplied to one or more of the coils, the respective one or more of the magnetic heads independently move in the axial direction. A rotary magnetic head device has a head supporting base plate, and a head supporting table which is tilted by an angle with respect to the head supporting base plate. The tilt angle is adjusted by moving the head supporting table. In a rotary magnetic lead device, the position in the axial direction of a magnetic head is detected, and the level of a current to be supplied to a coil is adjusted on the basis of the detection result.
