Abstract
A magnetic tape cartridge having at least one tape pack contains liners which form guide channels for the outer turns of the pack and/or for magnetic tape being wound or unwound and also include resilient sections for locating the tape pack and/or the winding hub in the central plane of the cartridge. The magnetic tape cartridge of the invention can be used with particular advantage as a compact cassette beacause of its outstanding reliability in operation.
Claims6
A magnetic tape cartridge with at least one tape-winding hub and with a pair of liners arranged symmetrically with respect to the mid-plane of the cartridge and interposed between the pack of wound tape and the upper and lower cartridge walls, respectively;
- said liners having end portions formed with an inclination towards said mid-plane so as to angle towards each other, in a direction radially outwardly of said hub, from a radially inner zone where they are at a substantial distance from the tape pack to and beyond a radially outer zone at which outer zone they engage the outer turns of the tape pack and so as to provide between them a guide channel for said outer turns, said channer at its bottom being delimited by the tape pack itself;
- and said liners having, spaced from said end portions in a direction opposite to said first-mentioned direction, other portions including resilient zones which engage the central area of the hub and tape pack combination to locate said combination in said mid-plane of the cartridge.
