Abstract
PURPOSE: To obtain a large signal with one read head, by selecting the refracive index of a thin film and the depth of a recess so as to impart the difference between light paths near to about 1/2 of the wavelength of the read light in recording information by irradiating a conductive film with a working beam to form recesses.
