发明名称 Floppy disks with enlarged partition-holes.
摘要 <p>Improved flexible disk pack magnetic storage systems and associated elements are illustrated as adapted for end-wise pneumatic partitioning and indicate, among other features, the use of &lt;&lt;rim means&gt;&gt; in the gap between adjacent flexible disks and surrounding holes therein, to better isolate the axial pressurized air streams through such holes from &lt;&lt;non-selected&gt;&gt; gaps and also to provide a reference surface for registration of the disks in the course of compressing the stack together; this &lt;&lt;rim means&gt;&gt; including &lt;&lt;annulets&gt;&gt; surrounding the holes not communicating pneumatically with a given gap and &lt;&lt;semi-annulets&gt;&gt; partly surrounding other holes which are in pneumatic communication with the gap -- and wherein such holes are circular except for the &lt;&lt;in-communication&gt;&gt; holes or orifices which are preferably enlarged by a &lt;&lt;crescentic cut-out&gt;&gt; opposite the respective &lt;&lt;semi-annulet&gt;&gt;</p>
