Abstract

Recording heads fabricated by sandwiching a thin slice of ferrite between two glass sides are shown in the figures. In each case, the ferrite consists of a C-shaped leg 1 and a plain rectangular leg 2 assembled to define a transducing gap 3. The ferrite is sufficiently thin to permit white light interference fringes, generated as a measure of the flying height over a record medium, to be observed through the glass.
