Abstract

Control of the writing current is possible with this equipment. The cassette, which is of the traditional type, consists of a rectangular plastics box in which tape is mounted on two spindle slots, accessible from the outside. A number of large and small windows in the cassette front edge, and a number of suitably positioned holes through the cassette allow the tape to be pressed against the various heads when the cassette is mounted in the recorder. The recorder itself has its three heads mounted on a movable plate, so that when the cassette has been placed in position, with its driving slots engaged with the driving spindles, the heads may be driven forward with a suitable pushbutton and brought into contact with the tape through the cassette windows.
