Apparatus for installing a tape leader on a hub, including a resilient locking member which can be projected into an undercut slot in the hub to press in a portion of the tape leader and lock it therein. A punch moves the locking member towards the hub slot, while a pair of pivotally mounted compressors move along opposite sides of the locking member to compress it and guide it into the hub slot.

Leader to hub locking device

In a system of the type wherein a floppy magnetic disc enclosed in an envelope stores data on both sides, unless great care is taken in inserting the floppy disc into the using apparatus, which reads from or writes thereon, one can accidentally or erroneously erase or write over data. This invention provides a floppy disc with a hole which can align with one or the other of a pair of two holes through an envelope in which said disc rotates. An opaque moveable means can be positioned to block one or the other of these pair of holes. A photocell will produce enabling signals by sensing light passing through only one of the pair of holes when the floppy disc is positioned one way in the using apparatus and through the other of the pair of holes when the floppy disc is positioned another way in the using apparatus. Accordingly, only when the floppy disc is correctly positioned in the using apparatus can the transducer head be enabled to write or read.
