Abstract
A cleaning tape has a base tape made of a synthetic resin and a cleaning layer formed on a surface of this base tape. The cleaning layer has a binding agent and a large number of spherical particles dispersed in the binding agent in a single particle layer. Such a cleaning tape is capable of removing very small unwanted protrusions and particles on the surface of a target object such as a magnetic hard disk without forming scratches.
