PCT No. PCT/IE96/00062 Sec. 371 Date Jun. 16, 1998 Sec. 102(e) Date Jun. 16, 1998 PCT Filed Sep. 16, 1996 PCT Pub. No. WO97/10596 PCT Pub. Date Mar. 20, 1997A cleaning device (1) for cleaning components (4,5,6,7,9,10,11) of a video unit comprises a cassette housing (15) having a pair of spools (24) rotatably mounted therein. A cleaning tape (30) is wound onto the spools (24) and is transferred from one spool (24) to the other on rotation thereof. The cleaning tape (30) when in a cleaning position engages the components (4,5,5,7,9,10,11) of the video unit. The cleaning tape (30) defines a central longitudinal central axis (46) which defines a sinusoidal waveform so that as the cleaning tape is wound from one spool (24) to the other along the magnetic tape path, the cleaning tape (30) cycles progressively over the components (4,5,6,7,9,10,11) for cleaning the magnetic tape path area (40) of the component and margin areas (41,42) on opposite sides of the area (40). The cycling of the cleaning tape (30) may be achieved by mechanical means.
