A drive apparatus for a magnetic disc, particularly a flexible magnetic disc in an envelope, distinguished by a compact design which is achieved by so designing and arranging the linkage between the drive's closure member and disc clamping member that they take up as little room as possible. By designing the linkage in the form of a roller and lever arrangement and arranging them substantially on the central longitudinal axis of the housing of the drive apparatus in the upper portion of the housing, the maximum amount of space is available on either side of the linking means for printed circuit boards and electronic components. In a very advantageous embodiment, the closure member, linkage and clamping member and part of the housing are assembled as a single unit which is ready for fitting. The drive apparatus of the invention can be used for any kind of flexible or rigid magnetic disc. |
