Cleaning tape with surface protrusions formed by particles of predetermined size/density and non-magnetic metal evaporated film of predetermined thickness

摘要

There is provided a cleaning tape capable of attaining sufficient cleaning effects while preventing electrostatic discharge damage to magnetoresistive heads or changes in reproduced output due to excessive head wear. The cleaning tape includes a non-magnetic substrate 1 , surface protrusions 6 formed on the non-magnetic substrate 1 with particles 2 having a particle diameter of 10 to 40 nm at a density of 300x10⁴ to 5000x10⁴ mm², a metal evaporated film 3 (preferably an electrically conductive layer such as an alloy layer containing Co as a primary component, an Al layer or the like) having a thickness of 10 to 200 nm and an inorganic protection film 4 having a thickness of 3 to 50 nm formed on the metal evaporated film 3.
