CLEANING CASSETTE

摘要

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.
