Abstract

The magnetic tape web comprises a support strip made from a thermoplastics or metal and coated on one or both sides with a magnetic storage layer. The strip is preformed such that in its rest position it forms itself into a spiral roll, cold forming being used in the case of a metal strip, and heat-setting in the case of a thermoplastics strip. The cassette containing the tape web is formed by a container and a cover, with the container (41) provided with two chambers (43, 45) for containing respective sections of the tape web and with a curved guide channel (46) between the chambers (43, 45) the channel having one or more openings (47, 50) to allow tape drive means and magnetic transducer means to contact the tape.
