Abstract
A magnetic cassette storage enclosure is described in the following specification, configured as a book-like pair of overlying covers that are hinged along a side analogous to a binding. One of the covers has a pivotal tray-like insert connected thereto that can be laid between the enclosure formed between the two covers. The tray-like insert has shelves or ledges formed in staggered relationship on the tray-like insert. The staggered shelves or ledges have a protuberance which locks a magnetic cassette into the tray while tabs receive the cassette spindle openings to prevent them from moving. The protuberances are spaced above the shelves or ledges. They are formed of a resilient material which can be flexed so as to frictionally engage the magnetic cassettes when inserted between the protuberances and the respective ledges in their staggered relationship. The second cover which is not connected to the tray-like insert has an outer sidewall therearound which forms an internal cavity or enclosure for the entire insert to maintain the magnetic cassettes in a dust-free environment. The insides of the top and bottom covers enclose the tray when they are laid in overlying relationship …
