Technique for the Examination of Contact Area of Magnetic Tapes
When a sample of magnetic recording material is pressed against the hypotenuse of a right-angle prism, total internal reflection is destroyed where intimate contact occurs. This effect has been utilized in a unique instrument for observing, measuring and photographing the extent and distribution of the contact area obtained between samples of magnetic recording materials and an idealized flat surface.
