Abstract
A rotary magnetic disc device suitable for use in a magnetic recording/reproducing apparatus in an electronic still camera or the like. In the rotary magnetic disc device, there are provided three height positioning pins which are used to set a regulation plate at a predetermnined recording/reproducing position opposite to a magnetic head with a magnetic disc therebetween, and two of the height positioning pins are located in the neighborhood of an axis of rotation of a cover on which a regulation plate holder is resiliently supported, the positioning pins being located at a predetermined distance from each other. The improved arrangement of the positioning pins contributes to reduction of not only the size of the regulation plate holder but also an operation force necessary to operate the cover when closing it.
