ABSTRACT:
A scanning type magnetic tape recorder comprises a deck including a rotatable scanning assembly mounted and at least one transducer and at least one capstan mounted in spaced relation to one side of the scanning assembly. A rotary drive is connected to rotate the transducer and the capstan at correlated speeds. A cassette, having a supply hub and a take-up hub in spaced relation, contains a quantity of tape movable between the hubs, and a drive belt passing in contact with portions of the tape wound on both the hubs. The cassette having an opening at one end of a size to fit around said scanning assembly.
Guides in the cassette locate a length of the tape between the hubs, away from the belt and across the opening in position to form a turn around the scanning assembly in response to placement of the cassette on said deck. A first roller guides a length of the belt where separated from the tape to one side of said opening for driving by the one capstan.
In one embodiment the cassette has supply and take-up hubs mounted in side by side relation spaced from the opening, and in a second embodiment the supply and take-up hubs are mounted in longitudinally spaced relation with respect to each other and to the opening. The cassettes of each embodiment have one end of common dimensions compatible with the receiver on said deck.
