To collect particulate matter in a head/disk assembly (HDA) in a controlled manner for further analysis, particle collectors in the form of double-coated tape are adhered at selected locations of the HDA enclosure interior surfaces. The collector size and shape are most conveniently selected as the size and shape of the sample holder of the device to be used for subsequent analysis. A typical tape for such use is a neoprene foam tape that withstands temperatures on the order of 250 degrees F for extended periods of time. An alternative material would be a metallic (such as silver) screen base material to which is applied a solvent base adhesive (such as a collodion) that retains adhesive qualities over an extended period.
