Abstract

The magnetic tape reel comprises a central core (2) and two side discs (4, 6) fitted to the latter. The core (2) has two coaxial rims (8, 10) joined together by a radial web, which has two coaxial annular edges on opposite sides in its central region. Each of the side discs (4, 6) has two coaxial annualr edges adjacent its centre on its inner face the outer edge resting against the outer rim (10) of the core (2) and the inner edge resting against one of the annular edges formed in the core (2). The second of the annular edges formed in the core (2). The second of the annular edges formed in the core (2) forms an annular blocking channel, together with the inner rim (8) of the core (2).
