PCT No. PCT/GB88/00483 Sec. 371 Date Dec. 21, 1989 Sec. 102(e) Date Dec. 21, 1989 PCT Filed Jun. 23, 1988 PCT Pub. No. WO88/10496 PCT Pub. Date Dec. 29, 1988.A cleaning cassette for cleaning the heads of streamer tape drives has a wiper arm (14) carrying a foam wiping pad (40) at one end and pivoted in the casing (12) at the other. A pick-up wheel (60) engages the capstan of the drive and reciprocates the wiper arm, through gear wheels (62,26) and a crank arm (30), to cause arcuate movement of the pad across the head. The pad has a thicker central portion (44) and thinner wings (46), and a metal base strip (42) is compressed over the wings. Effective head cleaning is achieved in a simple and practical structure without excessive head wear.
