Abstract
A diagnostic recording, readable by a computer system for enabling a user without special knowledge, software, or equipment to check, isolate and identify hardware malfunctions within the system, has a track with magnetic signals recorded thereon that is centered within a normal track space. A pair of void spaces of equal width remain within the normal track space on opposite sides of the track and extend parallel thereto. The track and the adjacent void spaces have special widths for diagnostic purposes.
