Abstract: A cassette system for any type of recording medium in strip or tape form, such as films and magnetic tapes, consists essentially of a housing whose external dimensions match those of a conventional type of cassette, and a protective holder for the recording medium which is wound into at least one roll. The housing and the holder are separate or separable members and can be fitted together. Both are provided with means for inserting the holder into the housing in the correct position, and for introducing the recording medium into the transport apparatus. The housing is provided with opening and closing means. The holder can be designed to be separable from the roll of recording medium. Preferably, the housing is a precision-made article and the holder a low-cost article.

Abstract: A tape cassette comprising at least one print-through echo-erasing device in the form of at least one appropriately shaped magnetic member made of permanent magnet material which is conveniently arranged on a tape guide element or near the apertures in the front wall of the cassette housing for the admission of scanning means. Such echo-erasing device can be used with advantage in any kind of magnetic tape cassette or cassette containing a recording medium having at least one magnetic track.

Abstract: A cassette arrangement for a recording medium in strip or tape form, particularly a magnetic tape, for use with a recording and/or playback apparatus having drive means and scanning means, comprising two separate components, viz. an approximately rectangular cassette housing and a protective reel-holder, at least said housing being of a construction permitting opening and closing thereof. The cassette housing has openings for admitting the drive means and scanning means and, in one of the openings which is located adjacent the front of the housing, guide means for the recording medium, and also having means for receiving, when the housing is open, said reel-holder in a predetermined position. The reel-holder accommodates the hub or hubs on which the recording medium is wound to form a reel or reels, in a location or locations such as to permit, in cooperation with the receiving means, introduction of the reel(s) into the open cassette housing in the correct position for operation.
