ABSTRACT:
Magnetic recording media called diskettes comprise a flexible magnetic disk which is enclosed in a jacket. The jacket has at least two openings therethrough. One of them is at the center on each side to enable the diskette to be engaged by a hub for rotating it, the other two are at opposite sides and comprise elliptic shaped openings which afford access for the reading head and for the pressure pad to opposite surfaces of a diskette. This invention provides doors which automatically cover the head and pressure pad access openings, except when a diskette is inserted into the reading mechanism at which time the door is automatically opened to enable the indicated access to the disk surfaces.
